By overriding getTile() and creating replay and image there, we can do
all preparations earlier and stop creating new tiles when we have maxed
out the frame time budget. It also allows us to get rid of the
drawTileImage override.
In OpenLayers 5, the following features are not supported anymore:
- Google Closure Compiler builds;
- custom builds.
The Google Closure Compiler is only kept for internal type checking.
To remove the following closure compiler warning:
```
Function module$node_modules$rbush$index.default: called with 1 argument(s). Function requires at least 2 argument(s) and at most 2.
```
`ol.tilegrid.WMTS.createFromCapabilitiesMatrixSet` fails when tileMatrix identifiers
are not prefixed by their tileMatrixSet identifier.
Original code by @filipheymans
In order to allow a user to select content within an element with the `.ol-selectable` class the `user-select` CSS property should be `text`.
The current value of `auto` results in a computed value of `none` due to the rule `.ol-viewport, .ol-unselectable` specifying `user-select: none`. According to the [the specification](https://www.w3.org/TR/css-ui-4/#valdef-user-select-auto):
> if the computed value of `user-select` on the parent of this element is `none`, the computed value is `none`
Tested manually on Chromium, Firefox and IE11.
The PDF was only generated AFTER requesting new tiles. When no new tiles where needed,
the callback never completed. Also fixed fitting the correct extent.
Fixes#7830.
This brings canvas polygon hit detection in parity with WebGL, where an
unfilled polygon will not be hit detected hovering inside the polygon.
Fixes#4846
This uses Closure Compiler to create a full build and run type checks.
Currently type errors are reported as warnings and the build is created
with SIMPLE optimizations until we have transitioned all types to path
types.
In rare cases, the previous font check returned false negatives when
checking against monospace only. By checking against another font, this
can be avoided.
See Issue #5881: setUrl was inherited from ol.source UrlTile, which creates a wrong tileUrlFunction: The official WMTS URL Template variables were no longer replaced.
Use the defined source projection despite it being equivalent to the rendering projection to enable using the specified alias code name instead of the code provided by the renderer's projection object. For example: The server only knows the name "EPSG:900913", which is an alias for the equivalent "EPSG:3857", that the renderer uses (by default).
This adds the pixelTolerance option parameter to the constructor of ol.interaction.Extent.
In this way the user can override the current default value of 10.
Also IMHO it doesn't make much sense to have issues of previous patch releases eg. 4.3.4 in here as these have their own release notes already, but I'll leave that for your debate
Previously, events weren't being propagated if the active draw
interaction had its `freehand` property set to true. This means that
you can't use your mouse wheel to zoom the map in freehand mode.
This change sets the default `pass` value to true and adds additional
logic to determine when it should be set to false (and stop event
propagation).
This commit also changes the TextReplay.drawText() signature, and moves
geometry calculation into drawText(). This improves performance where no
text needs to be rendered (TextStyle.getText() == ''), which is used often
in applications.
Having the coverage calculation code in the test files makes it hard to debug
tests, so it is better to only analyze coverage on Travis, and not locally.
There is a great deal of lines about Greenkeeper merges in the changelog, making it
hard to find real changes to the code.
This commit modifies the changelog task to exclude such lines.
This adds a unit test that tests weather the projection (spatial reference)
is being added inside the geometry object when writing features as
esriJson.
The WFS transaction failed if the srsDimension was not present on the
geometries.
Unit tests have been changed to accomodate the srsDimension attribute.
Contrary to Mapserver, Geoserver sets the srsDimension attribute on
the child of the geometry node, not on the points list.
This fix searches that node as well.
A small unit test was also added.
Changes to the layer were only propagated in some cases like addition/removal of a
layer to the group.
To make it consistent both with the rest of the group.js file and with the
layer.js file, the changes are now always notified.
Appears to have just been a typeo, using the minLon_, maxLon_ member variables rather than the function parameters provided.
This was creating very wide lines of parallel which were sometimes very slow in Chrome.
Until now, the features of transparent vector layers were rendered using
the layer opacity. This caused colors to mix together and the opacities
to stack up to an higher value than the expected layer opacity.
With this commit, the features are rendered at 100% opacity to an
intermediate canvas which ensures colors do not mix up even in the case
of features using an array of styles. The intermediate canvas is then
composed to the map canvas using the layer opacity.
Transparent layers are automatically detected, non-transparent layers
are not affected by the change.
As mentioned on issue 6992, EsriFormat was adding the spatial reference
outside the geometry, failing to insert data via the Arcgis rest API.
The spatial reference should be inside the geometry.
OriginalEvent 'mousemove' break default OL interaction move of map canvas. Using OL event 'pointermove' have same function and allow move of map canvas.
The previous x coordinate was one earth to the left which led to confusing results with everything.
This change makes sure the map is centered in a proper location (pretty much the same as before) WITHIN proper bounds.
This method does have value for users that want to switch between ol.Feature
and ol.render.Feature and still be able to use #getGeometry().getType() in a
style function to determine the feature geometry's type.
Some WFS servers like tinyOWS require the feature prefix to be in the
feature type for the feature to be found (eg `prefix:layer`).
The problem was, the prefix was always added to the feature type which
gave us a type name like `prefix:prefix:feature` or
`feature:prefix:feature`. The requests were then rejected by the WFS
server.
We now check if the feature type starts with the prefix. If it does, we
don't append it again. If it doesn't we do.
The code used to rely on the dimension. However, the dimension can only
be read from a GML3 document. This caused, for 3D geometries:
- An assertion error to be raised since the flatCoordinates list
contains more than 3 elements: "Assertion failed: flatCoordinates should
have a length of 3" The value of flatCoordinates for a 3D point was
something like `[2586394, 1232407, 0, 731, NaN, 0]`
- The value of the Z coordinates to be incorrect and always set to 0
This patch simplifies and correct the parsing of the coordinates:
- Don't parse groups of coords and the coordonates at the same time.
- Detect the dimension for the coordinates.
- If the Z coordinate exists, its value is used, otherwise, we use 0.
- Correct the presentation of test data to make it work with the new
parser.
- Add a test for a 3D point.
This enhance the procedure to find path of jsdoc binary by checking if the file exists.
It also use 2 possible paths to perform this check, one for npm and the other for yarn.
Close#6633
Previous typing was confusing the compiler. It could not figure out the
difference between the proj4 property and the constructor, which lead to
errors such as:

## Working with the build tool
As an OpenLayers developer you will use `make` to run build targets defined in the
`Makefile` located at the root of the repository. The `Makefile` includes
targets for running the linter, the compiler, the tests, etc.
The usage of `make` is as follows:
$ make <target>
where `<target>` is the name of the build target you want to execute. For
example:
$ make test
The main build targets are `serve`, `lint`, `build`, `test`, and `check`. The
latter is a meta-target that basically runs `lint`, `build`, and `test`.
The `serve` target starts a node-based web server, which we will refer to as the *dev server*. You'll need to start that server for running the examples and the tests in a browser. More information on that further down.
Other targets include `apidoc` and `ci`. The latter is the target used on Travis CI. See OpenLayers's [Travis configuration file](https://github.com/openlayers/openlayers/blob/master/.travis.yml).
## Running the `check` target
The `check` target is to be run before pushing code to GitHub and opening pull
requests. Branches that don't pass `check` won't pass the integration tests,
and have therefore no chance of being merged into `master`.
To run the `check` target:
$ make check
If you want to run the full suite of integration tests, see "Running the integration
tests" below.
## Running examples
To run the examples you first need to start the dev server:
$ make serve
$ npm run serve-examples
Then, just point your browser <http://localhost:3000/build/examples> in your browser. For example <http://localhost:3000/build/examples/side-by-side.html>.
Run examples against the `ol.js` standalone build:
The examples can also be run against the `ol.js` standalone build, just like
the examples [hosted](https://openlayers.org/en/master/examples/) on GitHub.
Start by executing the `host-examples` build target:
$ make host-examples
After running `host-examples` you can now open the examples index page in the browser: <http://localhost:3000/build/hosted/master/examples/>. (This assumes that you still have the dev server running.)
Append `?mode=raw` to make the example work in full debug mode. In raw mode the OpenLayers and Closure Library scripts are loaded individually by the Closure Library's `base.js` script (which the example page loads and executes before any other script).
Then, load <http://localhost:5000/> in your browser.
## Running tests
To run the tests in a browser start the dev server (`make serve`) and open <http://localhost:3000/test/index.html> in the browser.
To run the tests once:
To run the tests on the console (headless testing with PhantomJS) use the `test` target:
$ npm test
$ make test
To run the tests continuously during development:
See also the test-specific [README](../master/test/README.md).
## Running the integration tests
When you submit a pull request the [Travis continuous integration
server](https://travis-ci.org/) will run a full suite of tests, including
building all versions of the library and checking that all of the examples
work. You will receive an email with the results, and the status will be
displayed in the pull request.
To run the full suite of integration tests use the `ci` target:
$ make ci

### Use of the `goog` namespace in examples
Short story: the OpenLayers examples should not use the `goog` namespace, except
for `goog.require`.
Longer story: we want that the OpenLayers examples work in multiple modes, with the
standalone lib (which has implications of the symbols and properties we
export), and compiled together with the OpenLayers library.
Compiling the examples together with the library makes it mandatory to declare dependencies with `goog.require` statements.
[OpenLayers](https://openlayers.org/) is a high-performance, feature-packed library for creating interactive maps on the web. It can display map tiles, vector data and markers loaded from any source on any web page. OpenLayers has been developed to further the use of geographic information of all kinds. It is completely free, Open Source JavaScript, released under the 2-clause BSD License (also known as the FreeBSD).

#### Renamed `ol/source/TileUTFGrid` to `ol/source/UTFGrid`
The module name is now `ol/source/UTFGrid` (`ol.source.UTFGrid` in the full build).
#### Renaming of the `defaultDataProjection` in the options and property of the `ol/format/Feature` class and its subclasses
The `defaultDataProjection` option is now named `dataProjection`. The protected property available on the class is also renamed.
#### `transition` option of `ol/source/VectorTile` is ignored
The `transition` option to get an opacity transition to fade in tiles has been disabled for `ol/source/VectorTile`. Vector tiles are now always rendered without an opacity transition.
#### `ol/style/Fill` with `CanvasGradient` or `CanvasPattern`
The origin for gradients and patterns has changed from the top-left corner of the extent of the geometry being filled to 512 css pixel increments from map coordinate `[0, 0]`. This allows repeat patterns to be aligned properly with vector tiles. For seamless repeat patterns, width and height of the pattern image must be a factor of two (2, 4, 8, ..., 512).
#### Removal of the renderer option for maps
The `renderer` option has been removed from the `Map` constructor. The purpose of this change is to avoid bundling code in your application that you do not need. Previously, code for both the Canvas and WebGL renderers was included in all applications - even though most people only use one renderer. The `Map` constructor now gives you a Canvas (2D) based renderer. If you want to try the WebGL renderer, you can import the constructor from `ol/WebGLMap`.
Old code:
```js
importMapfrom'ol/Map';
constcanvasMap=newMap({
renderer:['canvas']
// other options...
});
constwebglMap=newMap({
renderer:['webgl']
// other options...
});
```
New code:
```js
importMapfrom'ol/Map';
importWebGLMapfrom'ol/WebGLMap';
constcanvasMap=newMap({
// options...
});
constwebglMap=newWebGLMap({
// options...
});
```
#### Removal of ol.FeatureStyleFunction
The signature of the vector style function passed to the feature has changed. The function now always takes the `feature` and the `resolution` as arguments, the `feature` is no longer bound to `this`.
Old code:
```js
feature.setStyle(function(resolution){
vartext=this.get('name');
...
});
```
New code:
```js
feature.setStyle(function(feature,resolution){
vartext=feature.get('name');
...
});
```
#### Changed behavior of the `Draw` interaction
For better drawing experience, two changes were made to the behavior of the Draw interaction:
1. On long press, the current vertex can be dragged to its desired position.
2. On touch move (e.g. when panning the map on a mobile device), no draw cursor is shown, and the geometry being drawn is not updated. But because of 1., the draw cursor will appear on long press. Mouse moves are not affected by this change.
#### Changes in proj4 integration
Because relying on a globally available proj4 is not practical with ES modules, we have made a change to the way we integrate proj4:
* The `setProj4()` function from the `ol/proj` module was removed.
* A new `ol/proj/proj4` module with a `register()` function was added. Regardless of whether the application imports `proj4` or uses a global `proj4`, this function needs to be called with the proj4 instance as argument whenever projection definitions were added to proj4's registry with (`proj4.defs`).
It is also recommended to no longer use a global `proj4`. Instead,
npm install proj4
and import it:
```js
importproj4from'proj4';
```
Applications can be updated by importing the `register` function from the `ol/proj/proj4` module
```js
import{register}from'ol/proj/proj4'
```
and calling it before using projections, and any time the proj4 registry was changed by `proj4.defs()` calls:
```js
register(proj4);
```
#### Removal of logos
The map and sources no longer accept a `logo` option. Instead, if you wish to append a logo to your map, add the desired markup directly in your HTML. In addition, you can use the `attributions` property of a source to display arbitrary markup per-source with the attribution control.
#### Replacement of `ol/Sphere` constructor with `ol/sphere` functions
The `ol/Sphere` constructor has been removed. If you were using the `getGeodesicArea` method, use the `getArea` function instead. If you were using the `haversineDistance` method, use the `getDistance` function instead.
The optional this (i.e. opt_this) arguments were removed from the following methods. Please use closures, the es6 arrow function or the bind method to achieve this effect (Bind is explained here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
#### `Map#forEachLayerAtPixel` parameters have changed
If you are using the layer filter, please note that you now have to pass in the layer filter via an `AtPixelOptions` object. If you are not using the layer filter the usage has not changed.
To bind a function to a this, please use the bind method of the function (See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
This change is due to the introduction of the `hitTolerance` parameter which can be passed in via this `AtPixelOptions` object, too.
### v4.6.0
#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`
To update your applications, simply replace `exceedLength` with `overflow`.
#### Deprecation of `ol.source.ImageVector`
Rendering vector sources as image is now directly supported by `ol.layer.Vector` with the new `renderMode: 'image'` configuration option. Change code like this:
```js
newol.layer.Image({
source:newol.source.ImageVector({
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
})
});
```
to:
```js
newol.layer.Vector({
renderMode:'image',
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
});
```
### v4.5.0
#### Removed GeoJSON crs workaround for GeoServer
Previous version of GeoServer returned invalid crs in GeoJSON output. The workaround in `ol.format.GeoJSON` used to read this crs code is now removed.
#### Deprecation of `ol.Attribution`
`ol.Attribution` is deprecated and will be removed in the next major version. Instead, you can construct a source with a string attribution or an array of strings. For dynamic attributions, you can provide a function that gets called with the current frame state.
Before:
```js
varsource=newol.source.XYZ({
attributions:[
newol.Attribution({html:'some attribution'})
]
});
```
After:
```js
varsource=newol.source.XYZ({
attributions:'some attribution'
});
```
In addition to passing a string or an array of strings for the `attributions` option, you can also pass a function that will get called with the current frame state.
```js
varsource=newol.source.XYZ({
attributions:function(frameState){
// inspect the frame state and return attributions
return'some attribution';// or ['multiple', 'attributions'] or null
}
});
```
### v4.4.0
#### Behavior change for polygon labels
Polygon labels are now only rendered when the label does not exceed the polygon at the label position. To get the old behavior, configure your `ol.style.Text` with `exceedLength: true`.
#### Minor change for custom `tileLoadFunction` with `ol.source.VectorTile`
It is no longer necessary to set the projection on the tile. Instead, the `readFeatures` method must be called with the tile's extent as `extent` option and the view's projection as `featureProjection`.
Before:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data));
tile.setProjection(format.readProjection(data));
// uncomment the line below for ol.format.MVT only
//tile.setExtent(format.getLastExtent());
});
```
After:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data,{
featureProjection:map.getView().getProjection(),
// uncomment the line below for ol.format.MVT only
//extent: tile.getExtent()
}));
);
```
#### Deprecation of `ol.DeviceOrientation`
`ol.DeviceOrientation` is deprecated and will be removed in the next major version.
The device-orientation example has been updated to use the (gyronorm.js)[https://github.com/dorukeker/gyronorm.js] library.
### v4.3.0
#### `ol.source.VectorTile` no longer requires a `tileGrid` option
By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22. If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
If you need to change the max zoom level, you can pass the source a `maxZoom` option. If you need to change the tile size, you can pass the source a `tileSize` option. If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
#### `ol.interaction.Modify` deletes with `alt` key only
To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex. If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option. For example, to allow deletion on a single click with no modifier keys, configure the interaction like this:
The motivation for this change is to make the modify, draw, and snap interactions all work well together. Previously, the use of these interactions with the default configuration would make it so you couldn't reliably add new vertices (click with no modifier) and delete existing vertices (click with no modifier).
#### `ol.source.VectorTile` no longer has a `tilePixelRatio` option
The `tilePixelRatio` option was only used for tiles in projections with `tile-pixels` as units. For tiles read with `ol.format.MVT` and the default tile loader, or tiles with the default pixel size of 4096 pixels, no changes are necessary. For the very rare cases that do not fall under these categories, a custom `tileLoadFunction` now needs to be configured on the `ol.source.VectorTile`. In addition to calling `tile.setFeatures()` and `tile.setProjection()`, it also needs to contain code like the following:
#### `ol.animate` now takes the shortest arc for rotation animation
Usually rotation animations should animate along the shortest arc. There are rare occasions where a spinning animation effect is desired. So if you previously had something like
```js
map.getView().animate({
rotation:2*Math.PI,
duration:2000
});
```
we recommend to split the animation into two parts and use different easing functions. The code below results in the same effect as the snippet above did with previous versions:
```js
map.getView().animate({
rotation:Math.PI,
easing:ol.easing.easeIn
},{
rotation:2*Math.PI,
easing:ol.easing.easeOut
});
```
### v4.2.0
#### Return values of two `ol.style.RegularShape` getters have changed
To provide a more consistent behaviour the following getters now return the same value that was given to constructor:
`ol.style.RegularShape#getPoints` does not return the double amount of points anymore if a radius2 is set.
`ol.style.RegularShape#getRadius2` will return `undefined` if no radius2 is set.
### v4.1.0
#### Adding duplicate layers to a map throws
Previously, you could do this:
```js
map.addLayer(layer);
map.addLayer(layer);
```
However, after adding a duplicate layer, things failed if you tried to remove that layer.
Now, `map.addLayer()` throws if you try adding a layer that has already been added to the map.
#### Simpler `constrainResolution` configuration
The `constrainResolution` configuration for `ol.interaction.PinchZoom` and `ol.interaction.MouseWheelZoom`
can now be set directly with an option in `ol.interaction.defaults`:
The v4.1.0 release includes features and fixes from 91 pull requests.
#### Interactive overview map
The extent rectangle on the overview map can now be dragged to control the view for the main map.
#### Setting min and max zoom for a view
You can now change the min or max zoom for a view after it has been created. This can be useful if you want to limit how far out users can zoom based on changes in viewport width (use `view.setMinZoom()` for this).
#### Adding duplicate layers to a map throws
Previously, you could do this:
```js
map.addLayer(layer);
map.addLayer(layer);
```
However, after adding a duplicate layer, things failed if you tried to remove that layer.
Now, `map.addLayer()` throws if you try adding a layer that has already been added to the map.

This is a patch release to fix several minor issues and two regressions in the [4.1.0 release](https://github.com/openlayers/openlayers/releases/tag/v4.1.0).
## Changes
* [#6711](https://github.com/openlayers/openlayers/pull/6711) - Correct path to cleancss ([@tschaub](https://github.com/tschaub))
The v4.2.0 release includes features and fixes from 87 pull requests.
#### New `movestart` event on `ol.Map`
The map now has a `movestart` event, as countarpart to the already existing `moveend` event.
#### New `moveTolerance` option in `ol.Map`
Some touch devices do not play well with OpenLayers's way of detecting clicks. To overcome this, a new `moveTolerance` option was introduced, so users can override the 1 pixel threshold above which a touch-release sequence won't be considered a click any more.
#### Support for multiple layers in `ol.format.TopoJSON`
With the new `layerName` and `layers` options, applications can extract the layer as additional attribute for vector features from `ol.format.TopoJSON`. This can especially be useful for styling vector tile layers.
#### New `tileJSON` option for `ol.source.TileJSON`
Like `ol.source.TileUTFGrid`, `ol.source.TileJSON` now also has a `tileJSON` option to configue it with inline TileJSON instead of a TileJSON URL.
#### New `ol.format.filter.during` filter
Although OpenLayers has no support for WFS v2.0, we added `ol.format.filter.during` for the `During` temporal operator.
#### Improved vector tile rendering at non-native resolutions
The vector tile renderer now uses an internal tile grid for all resolutions to cache pre-rendered tiles, even if the tile source does not have tiles for the viewed resolution. This improves rendering quality and performance.
#### New `insertVertexCondition` for `ol.interaction.Modify`
Applications can now control whether a vertex will be inserted into the modified geometry. This makes it easier to modify custom geometries.
#### New `callback` option for `ol.View#fit()`
To allow applications to perform custom actions when an animation associated with `ol.View#fit()` is completed, that method now has a new `callback` option.
#### New `ol.View#getInteracting()` getter
Like `ol.View#getAnimating()` returns `true` during a view animation, `ol.View#getInteracting()` returns `true` while users are interacting with the view.
#### New `hasZ` option for `ol.format.WFS#writeTransaction()`
When the new `hasZ` option is set to `true`, 3D coordinates will be preserved and encoded when writing a WFS transaction.
#### New `wrapX` option for `ol.source.Stamen`
Like other tile sources, `ol.source.Stamen` now also has a `wrapX` option, which allows applications to turn off wrapping the world in x direction.
#### Label support for `ol.Graticule`
The `ol.Graticule` component has several new options to add and control the output of labels. To turn on labelling, configure `ol.Graticule` with `showLabels: true`. The new options to control label formatting are `lonLabelFormatter`, `latLabelFormatter`, `lonLabelPosition` and `latLabelPosition`.
#### Return values of two `ol.style.RegularShape` getters have changed
To provide a more consistent behaviour the following getters now return the same value that was given to constructor:
`ol.style.RegularShape#getPoints` does not return the double amount of points anymore if a radius2 is set.
`ol.style.RegularShape#getRadius2` will return `undefined` if no radius2 is set.

The new `ol.Sphere.getArea()` and `ol.Sphere.getLength()` methods can be used to calculate spherical measures on geometries. This is the recommended over using the `geometry.getArea()` or `geometry.getLength()` methods.
Bad:
```js
geometry.getArea();
```
Good:
```js
ol.Sphere.getArea(geometry);
```
#### `ol.interaction.DragAndDrop` can be configured with a vector source
It is now possible to configure the drag and drop interaction with a vector source:
With this configuration, all features on the source are eligible for modification while the interaction is active.
#### `ol.interaction.Modify` deletes with `alt` key only
To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex. If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option. For example, to allow deletion on a single click with no modifier keys, configure the interaction like this:
The motivation for this change is to make the modify, draw, and snap interactions all work well together. Previously, the use of these interactions with the default configuration would make it so you couldn't reliably add new vertices (click with no modifier) and delete existing vertices (click with no modifier).
#### `ol.source.VectorTile` no longer requires a `tileGrid` option
By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22. If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
If you need to change the max zoom level, you can pass the source a `maxZoom` option. If you need to change the tile size, you can pass the source a `tileSize` option. If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
#### `ol.source.VectorTile` no longer has a `tilePixelRatio` option
The `tilePixelRatio` option was only used for tiles in projections with `tile-pixels` as units. For tiles read with `ol.format.MVT` and the default tile loader, or tiles with the default pixel size of 4096 pixels, no changes are necessary. For the very rare cases that do not fall under these categories, a custom `tileLoadFunction` now needs to be configured on the `ol.source.VectorTile`. In addition to calling `tile.setFeatures()` and `tile.setProjection()`, it also needs to contain code like the following:
#### `ol.animate` now takes the shortest arc for rotation animation
Usually rotation animations should animate along the shortest arc. There are rare occasions where a spinning animation effect is desired. So if you previously had something like
```js
map.getView().animate({
rotation:2*Math.PI,
duration:2000
});
```
we recommend to split the animation into two parts and use different easing functions. The code below results in the same effect as the snippet above did with previous versions:
```js
map.getView().animate({
rotation:Math.PI,
easing:ol.easing.easeIn
},{
rotation:2*Math.PI,
easing:ol.easing.easeOut
});
```

The 4.4.0 release includes features and fixes from 80 pull requests, including first time contributions from @EduardoNogueira, @ath0mas, @f7o, @trevorblades, @viethang, and @wb14123. There are some really nice rendering enhancements included in this release. It is now possible to render labels along lines (see [#7239](https://github.com/openlayers/openlayers/pull/7239) for more detail) and polygon labels are only rendered if they fit within the polygon ([#7292](https://github.com/openlayers/openlayers/pull/7292)). In addition, we now render tiles with an opacity transition, so tiled layers more gracefully fade in ([#7267](https://github.com/openlayers/openlayers/pull/7267)).
### Upgrade notes
#### Behavior change for polygon labels
Polygon labels are now only rendered when the label does not exceed the polygon at the label position. To get the old behavior, configure your `ol.style.Text` with `exceedLength: true`.
#### Minor change for custom `tileLoadFunction` with `ol.source.VectorTile`
It is no longer necessary to set the projection on the tile. Instead, the `readFeatures` method must be called with the tile's extent as `extent` option and the view's projection as `featureProjection`.
Before:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data));
tile.setProjection(format.readProjection(data));
// uncomment the line below for ol.format.MVT only
//tile.setExtent(format.getLastExtent());
});
```
After:
```js
tile.setLoader(function(){
vardata=// ... fetch data
varformat=tile.getFormat();
tile.setFeatures(format.readFeatures(data,{
featureProjection:map.getView().getProjection(),
// uncomment the line below for ol.format.MVT only
//extent: tile.getExtent()
}));
);
```
#### Deprecation of `ol.DeviceOrientation`
`ol.DeviceOrientation` is deprecated and will be removed in the next major version.
The device-orientation example has been updated to use the (gyronorm.js)[https://github.com/dorukeker/gyronorm.js] library.

The 4.5 release includes enhancements and fixes from 50 or so pull requests. Headlining this release, vector layers got a new `declutter` option that can be used to avoid overlapping labels. See the [street labels example](http://openlayers.org/en/latest/examples/street-labels.html) for a demonstration of this feature.
Please note that if you are using `closure-util` to build your OpenLayers based application, it is time to migrate to using the [`ol` package](https://www.npmjs.com/package/ol) and a module bundler like webpack. OpenLayers has not had a dependency on the Closure Library since the [3.19 release](https://github.com/openlayers/openlayers/releases/tag/v3.19.0); and with the 5.0 release we will be moving completely away from `goog.require` and `goog.provide`, dropping support for `closure-util`, and going with ES modules for our sources.
We will be adding details to the wiki about upcoming changes in 5.0 and tips on how to upgrade. We'll likely have a few more 4.x releases before the 5.0 release. But if you're interested in continuing to get feature enhancements in future releases, migrating to the `ol` package now will make the transition easier.
### Upgrade notes
#### Removed GeoJSON crs workaround for GeoServer
Previous version of GeoServer returned invalid crs in GeoJSON output. The workaround in `ol.format.GeoJSON` used to read this crs code is now removed.
#### Deprecation of `ol.Attribution`
`ol.Attribution` is deprecated and will be removed in the next major version. Instead, you can construct a source with a string attribution or an array of strings. For dynamic attributions, you can provide a function that gets called with the current frame state.
Before:
```js
varsource=newol.source.XYZ({
attributions:[
newol.Attribution({html:'some attribution'})
]
});
```
After:
```js
varsource=newol.source.XYZ({
attributions:'some attribution'
});
```
In addition to passing a string or an array of strings for the `attributions` option, you can also pass a function that will get called with the current frame state.
```js
varsource=newol.source.XYZ({
attributions:function(frameState){
// inspect the frame state and return attributions
return'some attribution';// or ['multiple', 'attributions'] or null
}
});
```

The 4.6 release includes enhancements and fixes from 30 or so pull requests. Headlining this release, vector layers got new `textBackgroundFill`, `textBackgroundStroke` and `padding` options that can be used to render background boxes for text. `ol.source.ImageVector` is now deprecated and replaced by a more convenient way to render vectors as images: by simply setting `renderMode: 'image'` on the vector layer.
Please note that if you are using `closure-util` to build your OpenLayers based application, it is time to migrate to using the [`ol` package](https://www.npmjs.com/package/ol) and a module bundler like webpack. OpenLayers has not had a dependency on the Closure Library since the [3.19 release](https://github.com/openlayers/openlayers/releases/tag/v3.19.0); and with the 5.0 release we will be moving completely away from `goog.require` and `goog.provide`, dropping support for `closure-util`, and going with ES modules for our sources.
See the [wiki](https://github.com/openlayers/openlayers/wiki/OpenLayers-v5.x) about upcoming changes in 5.0 and tips on how to upgrade. We likely won't have another 4.x release before the 5.0 release. If you're interested in continuing to get feature enhancements in future releases, migrating to the `ol` package now will make the transition easier.
### Upgrade notes
#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`
To update your applications, simply replace `exceedLength` with `overflow`.
#### Deprecation of `ol.source.ImageVector`
Rendering vector sources as image is now directly supported by `ol.layer.Vector` with the new `renderMode: 'image'` configuration option. Change code like this:
```js
newol.layer.Image({
source:newol.source.ImageVector({
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
})
});
```
to:
```js
newol.layer.Vector({
renderMode:'image',
style:myStyle,
source:newol.source.Vector({
url:'my/data.json',
format:newol.format.GeoJSON()
})
});
```

The main theme of the v5.0.0 release is an improved developer/user experience with OpenLayers. Toward this end, we have reworked the library as a set of ES Modules, completely removing any dependency on the Closure Compiler, and improving compatibility with mainstream module bundlers.
See the [hosted examples](https://openlayers.org/en/latest/examples/), [API docs](https://openlayers.org/en/latest/apidoc/), and [bundle tutorial](https://openlayers.org/en/latest/doc/tutorials/bundle.html) for the new syntax, but basic usage looks like this:
```js
import'ol/ol.css';
import{Map,View}from'ol';
importTileLayerfrom'ol/layer/Tile';
importOSMfrom'ol/source/OSM';
constmap=newMap({
target:'map',
layers:[
newTileLayer({
source:newOSM()
})
],
view:newView({
center:[0,0],
zoom:0
})
});
```
See below for specific notes on upgrading from 4.x releases. We'll be working on updating the website with improved documentation and examples. Take a look at the issue tracker if you're interested in contributing.
### Upgrade Notes
#### Renamed `ol/source/TileUTFGrid` to `ol/source/UTFGrid`
The module name is now `ol/source/UTFGrid` (`ol.source.UTFGrid` in the full build).
#### Renaming of the `defaultDataProjection` in the options and property of the `ol/format/Feature` class and its subclasses
The `defaultDataProjection` option is now named `dataProjection`. The protected property available on the class is also renamed.
#### `transition` option of `ol/source/VectorTile` is ignored
The `transition` option to get an opacity transition to fade in tiles has been disabled for `ol/source/VectorTile`. Vector tiles are now always rendered without an opacity transition.
#### `ol/style/Fill` with `CanvasGradient` or `CanvasPattern`
The origin for gradients and patterns has changed from the top-left corner of the extent of the geometry being filled to 512 css pixel increments from map coordinate `[0, 0]`. This allows repeat patterns to be aligned properly with vector tiles. For seamless repeat patterns, width and height of the pattern image must be a factor of two (2, 4, 8, ..., 512).
#### Removal of the renderer option for maps
The `renderer` option has been removed from the `Map` constructor. The purpose of this change is to avoid bundling code in your application that you do not need. Previously, code for both the Canvas and WebGL renderers was included in all applications - even though most people only use one renderer. The `Map` constructor now gives you a Canvas (2D) based renderer. If you want to try the WebGL renderer, you can import the constructor from `ol/WebGLMap`.
Old code:
```js
importMapfrom'ol/Map';
constcanvasMap=newMap({
renderer:['canvas']
// other options...
});
constwebglMap=newMap({
renderer:['webgl']
// other options...
});
```
New code:
```js
importMapfrom'ol/Map';
importWebGLMapfrom'ol/WebGLMap';
constcanvasMap=newMap({
// options...
});
constwebglMap=newWebGLMap({
// options...
});
```
#### Removal of ol.FeatureStyleFunction
The signature of the vector style function passed to the feature has changed. The function now always takes the `feature` and the `resolution` as arguments, the `feature` is no longer bound to `this`.
Old code:
```js
feature.setStyle(function(resolution){
vartext=this.get('name');
...
});
```
New code:
```js
feature.setStyle(function(feature,resolution){
vartext=feature.get('name');
...
});
```
#### Changed behavior of the `Draw` interaction
For better drawing experience, two changes were made to the behavior of the Draw interaction:
1. On long press, the current vertex can be dragged to its desired position.
2. On touch move (e.g. when panning the map on a mobile device), no draw cursor is shown, and the geometry being drawn is not updated. But because of 1., the draw cursor will appear on long press. Mouse moves are not affected by this change.
#### Changes in proj4 integration
Because relying on a globally available proj4 is not practical with ES modules, we have made a change to the way we integrate proj4:
* The `setProj4()` function from the `ol/proj` module was removed.
* A new `ol/proj/proj4` module with a `register()` function was added. Regardless of whether the application imports `proj4` or uses a global `proj4`, this function needs to be called with the proj4 instance as argument whenever projection definitions were added to proj4's registry with (`proj4.defs`).
It is also recommended to no longer use a global `proj4`. Instead,
npm install proj4
and import it:
```js
importproj4from'proj4';
```
Applications can be updated by importing the `register` function from the `ol/proj/proj4` module
```js
import{register}from'ol/proj/proj4'
```
and calling it before using projections, and any time the proj4 registry was changed by `proj4.defs()` calls:
```js
register(proj4);
```
#### Removal of logos
The map and sources no longer accept a `logo` option. Instead, if you wish to append a logo to your map, add the desired markup directly in your HTML. In addition, you can use the `attributions` property of a source to display arbitrary markup per-source with the attribution control.
#### Replacement of `ol/Sphere` constructor with `ol/sphere` functions
The `ol/Sphere` constructor has been removed. If you were using the `getGeodesicArea` method, use the `getArea` function instead. If you were using the `haversineDistance` method, use the `getDistance` function instead.
The optional this (i.e. opt_this) arguments were removed from the following methods. Please use closures, the es6 arrow function or the bind method to achieve this effect (Bind is explained here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
#### `Map#forEachLayerAtPixel` parameters have changed
If you are using the layer filter, please note that you now have to pass in the layer filter via an `AtPixelOptions` object. If you are not using the layer filter the usage has not changed.
To bind a function to a this, please use the bind method of the function (See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
This change is due to the introduction of the `hitTolerance` parameter which can be passed in via this `AtPixelOptions` object, too.

The first part is to include the JavaScript library. For the purpose of this tutorial, here we simply point to the openlayers.org website to get the whole library. In a production environment, we would build a custom version of the library including only the module needed for our application.
OpenLayers is a modular, high-performance, feature-packed library for displaying and interacting with maps and geospatial data.
The library comes with built-in support for a wide range of commercial and free image and vector tile sources, and the most popular open and proprietary vector data formats. With OpenLayers's map projection support, data can be in any projection.
## Public API
OpenLayers is available as [`ol` npm package](https://npmjs.com/package/ol), which provides all modules of the officially supported [API](../../apidoc).
## Renderers and Browser Support
By default, OpenLayers uses a performance optimized Canvas renderer. An experimental WebGL renderer (without text rendering support) is also avaialble.
OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io), the application bundle needs to be transpiled (e.g. using [Babel](https://babeljs.io)) and bundled with polyfills for `requestAnimationFrame`, `Element.prototype.classList` and `URL`.
The library is intended for use on both desktop/laptop and mobile devices, and supports pointer and touch interactions.
## Module and Naming Conventions
OpenLayers modules with CamelCase names provide classes as default exports, and may contain additional constants or functions as named exports:
```js
importMapfrom'ol/Map';
importViewfrom'ol/View';
```
Class hierarchies grouped by their parent are provided in a subfolder of the package, e.g. `layer/`.
For convenience, these are also available as named exports, e.g.
```js
import{Map,View}from`ol`;
import{Tile,Vector}from`ol/layer`;
```
In addition to these re-exported classes, modules with lowercase names also provide constants or functions as named exports:
Modern JavaScript works best when using and authoring modules. The recommended way of using OpenLayers is installing the [`ol`](https://npmjs.com/package/ol) package. This tutorial walks you through setting up a simple dev environment, which requires [node](https://nodejs.org) for everything to work.
In this tutorial, we will be using [Parcel](https://parceljs.org) to bundle our application. There are several other options, some of which are linked from the [README](https://npmjs.com/package/ol).
## Initial steps
Create a new empty directory for your project and navigate to it by running `mkdir new-project && cd new-project`. Initialize your project using `npm init` and answer the questions asked.
Add OpenLayers as dependency to your application with
npm install ol
At this point you can ask NPM to add required development dependencies by running
npm install --save-dev parcel-bundler
## Application code and index.html
Place your application code in `index.js`. Here is a simple starting point:
```js
import'ol/ol.css';
import{Map,View}from'ol';
importTileLayerfrom'ol/layer/Tile';
importOSMfrom'ol/source/OSM';
constmap=newMap({
target:'map',
layers:[
newTileLayer({
source:newOSM()
})
],
view:newView({
center:[0,0],
zoom:0
})
});
```
You will also need an `ìndex.html` file that will use your bundle. Here is a simple example:
```html
<!DOCTYPE html>
<html>
<head>
<metacharset="utf-8">
<title>Using Parcel with OpenLayers</title>
<style>
#map{
width:400px;
height:250px;
}
</style>
</head>
<body>
<divid="map"></div>
<scriptsrc="./index.js"></script>
</body>
</html>
```
## Creating a bundle
With simple scripts you can introduce the commands `npm run build` and `npm start` to manually build your bundle and watch for changes, respectively. Add the following to the script section in `package.json`:
```json
"scripts":{
"test":"echo \"Error: no test specified\" && exit 1",
"start":"parcel index.html",
"build":"parcel build --public-url . index.html"
}
```
That's it. Now to run your application, enter
npm start
in your console. To test your application, open http://localhost:1234/ in your browser. Whenever you change something, the page will reload automatically to show the result of your changes.
Note that a single JavaScript file with all your application code and all dependencies used in your application has been created. From the OpenLayers package, it only contains the required components.
To create a production bundle of your application, simply type
npm run build
and copy the `dist/` folder to your production server.
The core component of OpenLayers is the map (`ol.Map`). It is rendered to a `target` container (e.g. a `div` element on the web page that contains the map). All map properties can either be configured at construction time, or by using setter methods, e.g. `setTarget()`.

`ol.Map` is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of an `ol.View` instance.
`Map` is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of a `View` instance.
```js
map.setView(new ol.View({
import View from 'ol/View';
map.setView(new View({
center: [0, 0],
zoom: 2
}));
```
An `ol.View` also has a `projection`. The projection determines the coordinate system of the `center` and the units for map resolution calculations. If not specified (like in the above snippet), the default projection is Spherical Mercator (EPSG:3857), with meters as map units.
A `View` also has a `projection`. The projection determines the coordinate system of the `center` and the units for map resolution calculations. If not specified (like in the above snippet), the default projection is Spherical Mercator (EPSG:3857), with meters as map units.
The `zoom` option is a convenient way to specify the map resolution. The available zoom levels are determined by `maxZoom` (default: 28), `zoomFactor` (default: 2) and `maxResolution` (default is calculated in such a way that the projection's validity extent fits in a 256x256 pixel tile). Starting at zoom level 0 with a resolution of `maxResolution` units per pixel, subsequent zoom levels are calculated by dividing the previous zoom level's resolution by `zoomFactor`, until zoom level `maxZoom` is reached.
## Source
To get remote data for a layer, OpenLayers uses `ol.source.Source` subclasses. These are available for free and commercial map tile services like OpenStreetMap or Bing, for OGC sources like WMS or WMTS, and for vector data in formats like GeoJSON or KML.

OpenLayers is a big library providing a lot of functionality. So it is unlikely that an application will need and use all the functionality OpenLayers provides. This is why creating application-specific OpenLayers builds, with just the functionality your application needs, is often a good idea.
An alternative to creating custom builds is to compile your application code together with OpenLayers. See the [Compiling Application with Closure Compiler](closure.html) tutorial for more information.
This particular tutorial explains how to create custom builds of OpenLayers.
## Requirements
OpenLayers's build tools use Node and Java, so you need to have Node and Java installed on your machine. You can run `node --version` and `java -version` to test that Node and Java are installed, respectively. See [developing guide](https://github.com/openlayers/openlayers/blob/master/DEVELOPING.md) for minimum version numbers required.
## Download OpenLayers
Obviously, creating a custom build requires the OpenLayers source and specific build scripts.
To get the OpenLayers source and the build scripts you can clone the openlayers [repository](https://github.com/openlayers/openlayers), or you can download one of the release archives. You can also download the `openlayers` Node package from the Node package registry, using NPM (the Node Package Manager). This is the method we are going to use in this tutorial.
Create a directory:
$ mkdir openlayers
Download the OpenLayers distribution using NPM:
$ npm install openlayers
This will download the latest stable version of OpenLayers, and install it under `node_modules`. You can list the content of `node_modules` to verify that it effectively contains a directory named "openlayers".
The Node packages onto which the `openlayers` package depends are installed under `node_modules/openlayers/node_modules`. That directory should, for example, include `closure-util`, which is the utility library OpenLayers uses for Closure.
You should now have everything you need to create custom builds of OpenLayers!
## Create a build configuration file
Creating a custom build requires writing a build configuration file. The format of build configuration files is JSON. Here is a simple example of a build configuration file:
```json
{
"exports":[
"ol.Map",
"ol.View",
"ol.control.defaults",
"ol.layer.Tile",
"ol.source.OSM"
],
"compile":{
"externs":[
"externs/bingmaps.js",
"externs/closure-compiler.js",
"externs/geojson.js",
"externs/oli.js",
"externs/olx.js",
"externs/proj4js.js",
"externs/tilejson.js",
"externs/topojson.js"
],
"extra_annotation_name":[
"api","observable"
],
"compilation_level":"ADVANCED",
"manage_closure_dependencies":true,
"rewrite_polyfills":false
}
}
```
Create a file named `ol-custom.json` with that content, and save it under the `node_modules/openlayers/build` directory. (You can save it to any location really.)
The most relevant part of this configuration object is the `"exports"` array. This array declares the functions/constructors you use in your JavaScript code. For example, the above configuration file is what you'd use for the following JavaScript code:
```js
varmap=newol.Map({
target:'map',
layers:[
newol.layer.Tile({
source:newol.source.OSM()
})
],
controls:ol.control.defaults({
attributionOptions:{
collapsible:false
}
}),
view:newol.View({
center:[0,0],
zoom:4
})
});
```
Note that this JavaScript code corresponds to OpenLayers's [`simple`](https://openlayers.org/en/master/examples/simple.html) example.
You are now ready to create your first OpenLayers build. Use the following command to create the build:
The build command may take some time, but it should end with an output in the console such as the following:
info ol Parsing dependencies
info ol Compiling 364 sources
The build command should have created an `ol-custom.js` file in the `node_modules/openlayers/build` directory. You can verify that the file was created. You can even open it in your editor if you're curious.
As a test, you can use the following HTML file to verify that your custom build works as expected:
Closure allows you to define constants that can be set at compile time. The OpenLayers code defines several such values.
Setting some of these to `false` means that the portions of the code relating to this setting become "dead", i.e. are never executed. As Closure Compiler's `ADVANCED` mode removes dead code, this makes the size of the advanced compiled file smaller.
You might have noticed that the build file you've just created is considerably smaller than the full build, but it can be reduced further. This is because both renderers and other optional code are included by default. We only need one renderer, and we do not use the optional code, so can exclude what we don't use by setting properties with `define`s. So add a define section to the config above:
```
"define": [
"ol.ENABLE_WEBGL=false",
"ol.ENABLE_PROJ4JS=false",
"ol.ENABLE_RASTER_REPROJECTION=false"
],
```
and re-run the build script. The build size should now be smaller.
### Externs
The Closure documentation explains that "externs" are for external names used in the code being compiled. The compiler includes externs for built-ins such as `document`. The `externs` directory of the OpenLayers code includes files for all those used in some part of the library. For example, if you use Bing Maps, you should include the Bing externs file in the `externs` section of the config file.
`oli.js` and `olx.js` are externs files for the OpenLayers API. For example `olx.js` includes extern definitions for OpenLayers's constructor options. `closure-compiler.js` fixes any issues that may arise with a specific compiler version. You should always use these three files as externs when creating custom builds.
### Other compiler options
There are a couple of other compiler options in the config file above. `manage_closure_dependencies` and `rewrite_polyfills` should always be used.
You can specify any of the other compiler options here as needed, such as the renaming reports, output manifest, or source maps. There is a full list of available options in [closure-util](https://github.com/openlayers/closure-util/blob/master/compiler-options.txt).
Note that `build.js` currently requires you to enter an output file and will write the output from the compiler to it; it does not use the `js_output_file` compiler option. If you specify this in the config file, there will be no compiler output, so `build.js`'s output file will be empty.
## A more complicated example
Now let's try a more complicated example: [`heatmaps-earthquakes`](https://openlayers.org/en/master/examples/heatmap-earthquakes.html). The build configuration file looks like this:
```json
{
"exports":[
"ol.layer.Heatmap",
"ol.source.Vector",
"ol.format.KML",
"ol.layer.Heatmap#getSource",

The exports are given here in the order in which they occur in the `heatmaps-earthquakes` example's JavaScript code. In this example we not only use the `ol.` functions and constructors, but also `prototype` methods where the `ol` namespace is not directly used. In the code, we have for example `vector.getSource().on()`. This means we are using the `getSource` method of `layer.Heatmap` and the `on` method of `source.KML`, so this is what has to be exported. Similarly, `event.feature.get()` means we are using the `feature` property of `source.Vector.Event` and the `get` method of `Feature`. If any of these names are left out, the compile will complete successfully, but the missing names will be obfuscated and you will get a 'property undefined' error when you try and run the script.
## Maintaining the code
If you installed OpenLayers from the Node package, you can use `npm` to upgrade to the latest version. If you cloned the Github repo, simply pulling in the latest code may not be enough, as some of the packages used, for example, the compiler, may need upgrading too. Do this by using `npm install` rather than `npm update`.
## Conclusion
This tutorial should have given you the information you need to create custom builds, i.e. builds tailored to your application. See the [tasks readme](https://github.com/openlayers/openlayers/tree/master/tasks/readme.md) for more information on the build scripts and the properties you can use in the build configuration file.
With version 3, the OpenLayers web mapping library was fundamentally redesigned. The widely used version 2 dates from the early days of Javascript development, and was increasingly showing its age. So it has been rewritten from the ground up to use modern design patterns.
The initial release aims to support much of the functionality provided by version 2, with support for a wide range of commercial and free tile sources, and the most popular open-source vector data formats. As with version 2, data can be in any projection. The initial release also adds some additional functionality, such as the ability to easily rotate or animate maps.
It is also designed such that major new features, such as displaying 3D maps, or using WebGL to quickly display large vector data sets, can be added in later releases.
## Google Closure
OpenLayers was written in a way so it can be compiled with [__Closure Compiler__](https://developers.google.com/closure/compiler/). Its 'advanced' compilation mode offers a level of compression that exceeds anything else available.
## Public API
Using the advanced optimizations of the Closure Compiler means that properties and methods are renamed – `longMeaningfulName` might become `xB` – and so are effectively unusable in applications using the library. To be usable, they have to be explicitly `exported`. This means the exported names, those not renamed, effectively become the public API of the library. These __exportable__ properties and methods are marked in the source, and documented in the [API docs](../../apidoc). This is the officially supported API of the library. A build containing all these exportable names is known as a __full build__. A hosted version of this is available, which can be used by any application.
## Custom Builds
Unlike in, say, Node, where a module's exports are fixed in the source, with Closure Compiler, exports can be defined at compile time. This makes it easy to create builds that are customized to the needs of a particular site or application: a __custom build__ only exports those properties and methods needed by the site or application. As the full build is large, and will probably become larger as new features are added to the API, it's recommended that sites create a custom build for production software.
## Renderers and Browser Support
The library currently includes two renderers: Canvas and WebGL. Both of them support both raster data from tile/image servers, and vector data; WebGL however does not support labels. Clearly only those browsers that [support Canvas](http://caniuse.com/canvas) can use the Canvas renderer. Equally, the WebGL renderer can only be used on those devices and [browsers](http://caniuse.com/webgl) that support WebGL.
OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io) for `requestAnimationFrame` and `Element.prototype.classList` are required, and using the KML format requires a polyfill for `URL`.
The library is intended for use on both desktop/laptop and mobile devices.
## Objects and Naming Conventions
The top-level namespace is `ol` (basically, `var ol = {};`). Subdivisions of this are:
* further namespaces, such as `ol.layer`; these have a lower-case initial
* simple objects containing static properties and methods, such as `ol.easing`; these also have a lower-case initial
* types, which have an upper-case initial. These are mainly 'classes', which here means a constructor function with prototypal inheritance, such as `ol.Map` or `ol.layer.Vector` (the Vector class within the layer namespace). There are however other, simpler, types, such as `ol.Extent`, which is an array.
Class namespaces, such as `ol.layer` have a base class type with the same name, such as `ol.layer.Layer`. These are mainly abstract classes, from which the other subclasses inherit.
Source files are similarly organised, with a directory for each class namespace. Names are however all lower-case, for example, `ol/layer/vector.js`.
OpenLayers follows the convention that the names of private properties and methods, that is, those that are not part of the API, end in an underscore. In general, instance properties are private and accessed using accessors.

## TileGrid and Extents
When reprojection is needed, new tiles (in the target projection) are under the hood created from the original source tiles.
The TileGrid of the reprojected tiles is by default internally constructed using `ol.tilegrid.getForProjection(projection)`.
The TileGrid of the reprojected tiles is by default internally constructed using `ol/tilegrid~getForProjection(projection)`.
The projection should have extent defined (see above) for this to work properly.
Alternatively, a custom target TileGrid can be constructed manually and set on the source instance using `ol.source.TileImage#setTileGridForProjection(projection, tilegrid)`.
Alternatively, a custom target TileGrid can be constructed manually and set on the source instance using `ol/source/TileImage~setTileGridForProjection(projection, tilegrid)`.
This TileGrid will then be used when reprojecting to the specified projection instead of creating the default one.
In certain cases, this can be used to optimize performance (by tweaking tile sizes) or visual quality (by specifying resolutions).
# How it works
The reprojection process is based on triangles -- the target raster is divided into a limited number of triangles with vertices transformed using `ol.proj` capabilities ([proj4js](http://proj4js.org/) is usually utilized to define custom transformations).

### Disabling reprojection
In case you are creating a custom build of OpenLayers and do not need the reprojection code, you can reduce the build size by setting `ol.ENABLE_RASTER_REPROJECTION` to `false`, which completely disables the reprojection support.
See [Custom builds](custom-builds.html#defines) tutorial on how to do this.

### Resolution calculation
When determining source tiles to load, the ideal source resolution needs to be calculated.
The `ol.reproj.calculateSourceResolution(sourceProj, targetProj, targetCenter, targetResolution)` function calculates the ideal value in order to achieve pixel mapping as close as possible to 1:1 during reprojection, which is then used to select proper zoom level from the source.
The `ol/reproj~calculateSourceResolution(sourceProj, targetProj, targetCenter, targetResolution)` function calculates the ideal value in order to achieve pixel mapping as close as possible to 1:1 during reprojection, which is then used to select proper zoom level from the source.
It is, however, generally not practical to use the same source zoom level for the whole target zoom level -- different projections can have significantly different resolutions in different parts of the world (e.g. polar regions in EPSG:3857 vs EPSG:4326) and enforcing a single resolution for the whole zoom level would result in some tiles being scaled up/down, possibly requiring a huge number of source tiles to be loaded.
Therefore, the resolution mapping is calculated separately for each reprojected tile (in the middle of the tile extent).
