Now testing with two features and adding a call to `prepareFrame`
without which the final render transform was off.
Also added a test with a pixelratio > 1.
For each feature its opacity value index is encoded on 4 bytes
in the color values, and the uid is stored in the opacity
value, allowing for a much higher range of uids to be read.
Now two methods are available: `readAll` and `readPixel`,
and the data from the render target is not re-read every time unless
`clearCachedData` is called.
For now only `forEachFeatureAtCoordinate` is implemented.
Each time the viewport is rendered, another similar render pass is
done using the specific hit detection instructions. Feature uid's are
encoded in the r,g,b,a channels and can then be decoded on the fly.
Note: the `readPixels` operation is taking a lot of time,
around 10-20ms each frame.
Hit detection is done by rendering features with their id encoded in the
color attribute. A parallel set of render instructions and a second
vertex buffer is used specifically for that.
Previously features were indexed by uid only when they
did not have a defined id.
A new method was added: `getFeatureByUid`. This is not part of
the public API.
This will facilitate the lookup of features for hit detection.
The worker currently works by receiving GENERATE_BUFFERS messages and
will send back the same kind of message, with the generated buffers
attached. All properties of the original message are kept, so that
when a GENERATE_BUFFERS message comes back to the main thread it
is possible to know what and how the buffers where generated.
This is typically used for the `projectionTransform` matrix, and
will also be necessary when working with tiles.
The worker receives a transferable array of instructions
and sends back two transferable arrays (vertex and index buffer).
The projection transform is also sent so that when the main thread
receives the buffers from the worker it also knows which projection to
apply when rendering the geometries.
The base webgl renderer module now has two types of utilities:
* `writeXFeatureInstructions` will write a series of values in a given
typed array, which represent how a given feature will be rendered; for points,
this means position, size, color, etc.
* `writeXFeatureToBuffers` will fill up the given index & vertex buffers
with values based on the provided render instructions
As such, the logic for rendering features is:
user-input style > instructions array >(*) index/vertex buffers > draw
(*) this transformation is intended to be done on a worker.
Add a filter function to the translate interaction. This filter is similar to the one present in the select interaction options and provides the ability to dynamically filter which features to include in the translate interaction. Adding the existing "features" options allows further filtering to take place. In this case the filter is first applied, and features that are passing the filtering need to be present in the "features" options to be further kept. The default filter function always return true (no filtering).
...in the collection.
Previously two features with the same id could be pushed manually in the
features collection and stay there.
This would cause an error when clearing the source.
Fixes#6183.
The recent addition of tilePixelRatio to the Zoomify.js/CustomTile constructor broke parameter binding in IIIF.js/IIIF.
The fix mirrors the change in the Zoomify.js/Zoomify constructor
The `WebGLHelper` class now provides a `makeProjectionTransform` method
that updates a transform to match the projection for a given frame state.
This also means that the WebGLHelper does not set the projection matrix
uniform anymore, this is the responsibility of the renderer as
the rendered coordinates will not be in world space from now on.
This uses an undocumented method to trigger a synchronous redraw
instead of using the standard schedule from Mapbox. The CSS previously used
to make the OL and MB views match is not necessary anymore.
Reference: https://github.com/mapbox/mapbox-gl-js/issues/7893#issue-408992184
IIIF Image API 3 allows context extensions that should be added to the
info.json's @context property. Therefore, '@context' might be an array
instead of a string.
60: "Missing or invalid `size`."
Without at least a size, no IIIF can be displayed.
61: "Cannot determine IIIF Image API version from provided image
information JSON."
Without finding out the version information, one could only guess how to
use the image info JSON.
src/ol/source/IIIF.js contains a tile source for IIIF Image API services.
It supports Image API version 1 and 2 on compliance levels 0, 1 and 2.
To get working constructor options for IIIF from an IIIF image info.json,
use src/ol/format/IIIFInfo.js.
An example is available in examples/iiif.html respectivly examples/iiif.js.
The transpiling step is done by babel instead of bublé now.
Bublé caused the istanbul instrumenter step to crash because of an
unexpected SourceMap object format.
Previously, an interaction could begin while target values
(center/resolution) were out of the allowed range, causing a
glitch where the view zoom/position would jump suddenly.
By default, alpha premultiplying should be done by the initial rendering
(eg quads) and not the final post processing pass.
The default post processing pass expects premultiplied color values and
will not do this operation itself.
This also makes it possible to call `solveConstraints_` with a duration of 0,
which means the target values are modified straight away without triggering
an animation or leaving the current flow.
The renderer now accesses the zDirection member directly if it exists.
This also has the advantage of not advertising any object methods that
hav no use for most tile sources.
The zDirection addition to the Zoomify tile source only takes effect through
the renderer, so these two renderer cases are added to test the behavior.
zoomify-no-zdirection expects the default behavior.
zoomify-zdirection expects the tiles for the next better resolution.
Via zDirection, the renderer's selection of a tile source's resolution can be
controlled if the view's resolution does not match any tile source resolution.
Currently the zDirection option is only available for Zoomify. The comment
https://github.com/openlayers/openlayers/issues/9343#issuecomment-474341033
describes why caution is advised when using zDirection for other sources.
ol/source/Tile~TileSource#getZDirection has been added to avoid having the
getZDirection method solely in the Zoomify source - just to document the
possibility.
Transforms the old rendering tests for the VectorImageLayer
to the new rendering test approach.
The declutter tests are kept in the old format for know.
- This sets ignore to false if a method tagged with
inheritdoc has a matching ancestor. It also stops iterating
when a match is found.
- Outdated TODO is removed, too.
this commit enhances the readability of
tile debug coordinates by adding a stroke
for better readability on aerial imagery
and a maxWidth for high zoom levels

This downgrades puppeteer to version `~1.11.0`.
This will download the stable version of chromium
(72.0.3582.0). The current puppeteer version
(`^1.12.2`) downloads the beta version of
chromium (73.0.3679.0).
Previously the formula for the resolution constraint allowed going way past
the minimum zoom.
Also adjusted the center constraint to avoid a zigzag effect when going out
of resolution bounds.
The DragPan, KeyboardPan and DragZoom interactions now make sure to
animate to a valid center/resolution target to avoid
a chained "resolve" animation which looks weird.
The `View.fit` method was also fixed to use this.
API changes:
* (breaking) the `rotate` method is gone
* the `adjustRotation`, `adjustResolution` and `adjustZoom` methods are now
available and allow using an anchor.
This means interactions do not have to do the anchor computation themselves
and this also fix anchor computation when constraints must be applied.
This introduces a breaking change.
This options replaces the various `constrainResolution` options on interactions
and the `fit` method.
Since constraints are now the responsibility of the View, the fact that intermediary
zoom levels are allowed or not is now set in the view options.
By default, the view resolution is unconstrained.
This is done by applying the center constraint differently when we're in the
middle of an interaction/animation or not.
When the view is moving, the center constraint will restrain the given value
in an "elastic" way, using a logarithmic function.
This can be disabled using the `smoothCenterConstrain` view parameter.
This will help making sure that the view will come back to a "rested" state
once the interactions are over.
Interactions no longer need to handle the animation back to a rested state,
they simply call `endInteraction` with the desired duration and direction.
This commit aims to simplify the computation of zoom and resolution in the
View class.
Previously zoom levels and resolution computations were mixed in different places,
ie resolution constraints, initial values, etc.
Now the View class only has the `getZoomForResolution` and `getResolutionForZoom`
methods to convert from one system to another.
Other than that, most computations use the resolution system internally.
The `constrainResolution` method also does not exist anymore, and is replaced
by `getValidResolution` and `getValidZoomLevel` public methods.
This introduces a breaking change:
The `extent` view option now constrains the whole viewport and not just the
view center.
The option `constrainOnlyCenter` was added to keep the previous behaviour.
Constraining the whole viewport and not only the view center means
that the center and resolution constraints must be applied with a knowledge of
the viewport size.
The `getValidZoomLevel` apply the current resolution constraint to return
a value that is guaranteed valid.
This is used for interactions & controls which need a target value to work:
the +/- buttons, the zoom clider, the dragbox zoom and the mouse wheel zoom.
The view now has targetCenter, targetRotation and targetResolution members.
These hold the new values given by set* methods. The actual view parameters are then changed by
calling `applyParameters_`.
The TileJSON spec does not specify the tile size
and there is no TileJSON property specifying the value.
Many providers nowadays provide 512x512 with TileJSON.
- Rename linearRingIsOriented => linearRingsAreOriented
The function checks all linear rings of a Polygon, so
the plural "rings" is more appropriate
- Rename linearRingsAreOriented => linearRingssAreOriented
The double s is appropriate because the check is done for
all Polygons of a MultiPolygon
This commit restores the function names from OpenLayers v4,
they were changed (wrongly IMHO) in #7820.
Things done:
- stay closer to the original rendering in canvas
- get rid of the intermediary blur step
- use the new callbacks in the webgl points renderer
- premultiply alpha in the last postprocessing step
Now the shader and program caches are simply arrays of native WebGL created objects.
The WebGLHelper simply takes the sources of the frag and vert shader and produces a program.
This removes 2 classes & reduces the general verbosity of the API.
Also a `getShaderCompilationErrors` was added on `WebGLHelper` to help debug GLSL errors.
Executors are use to render instructions.
They do not contain cod for building instructions.

ol/renderer/vector was using the abstract ReplayGroup type while
referencing replayGroup.addDeclutter(), which was only defined
on the canvas and webgl implementations and was also defined
differently.
- Added JSDoc to getRenderer()
- Cast default options to types
- Cast event to MouseEvent to satisfy tsc. Non mouse/touch events
will simply produce [NaN, NaN]
- Cast to Layer before calling getSource(), as it does not exist
on Base
tsc considers everything in the else block to be of type 'never',
since it thinks that cosh is permanently defined for Math. Casting
back to Math in the else block fixes the error.
Remove 'extent' because the parent Source class does not contain
'extent' on its options or use options.extent in the constructor.
Also removed 'extent' from 'Options' for 'TileSource'.
Fixed constructor docs specifying optional options without a
default value. Fixed malformed @link tag in typedef description.
canvasFunction type was previously declared with the 'this' type
as ImageCanvas, but the 'this' ref was not passed on the scope when
calling the function.
The parent class does not accept an extent on its options. Also
check that the image is an img or video tag before setting the
source as Canvas does not have the src property.
If `VOID` is used, TypeScript is not able to figure out what the function parameters are.
Before:
```
$ npx tsc | wc -l
1188
```
After:
```
$ npx tsc | wc -l
1169
```
I'm not entirely sure that I like this pattern, but there does not
appear to be a better option since TypeScript would recommend:
function(this: SomeClass, ...)
tsdoc does not appear to support an associated annotation for the
function a la @this {SomeClass}.
Remove the following errors from the TypeScript checks:
```
src/ol/pointer/TouchSource.js(231,23): error TS2339: Property 'webkitRadiusX' does not exist on type 'Touch'.
src/ol/pointer/TouchSource.js(232,24): error TS2339: Property 'webkitRadiusY' does not exist on type 'Touch'.
src/ol/pointer/TouchSource.js(233,26): error TS2339: Property 'webkitForce' does not exist on type 'Touch'.
```
The only reference that I've found for these properties is a warning message from Google Chrome:
```
'Touch.webkitRadiusX' is deprecated and will be removed in M47, around November 2015. Please use 'Touch.radiusX' instead.
```
TypeScript doesn't like the current implementation:
```
src/ol/control/MousePosition.js(82,64): error TS2339: Property 'undefinedHTML' does not exist on type 'never'.
```
Some WMTS getCapabilities return <MatrixSet><TopLeftCorner> with more than one whitespace as delimiter between the coordinates. This leads to the layer not being displayed, because the origin_ property of ol.tilegrid.TileGrid is not set.
Error in ol.tilegrid.TileGrid.prototype.getTileCoordForXYAndZ_: JavaScript runtime error: Unable to get property '0' of undefined or null reference
It is often useful in application code to have a way to uniquely identify
and object.
Exposing the OpenLayers mechanism allows for best performance and avoid
unneccessary dirt.
TileWMS objects take a gutter option but do not have a public getter
for it. This makes it convoluted for user code to recreate the object
(ex: in the case of serialization/deserialization).
- the getGutterInternal() method is renamed to getGutter;
- the getGutter(projection) method is renamed to getGutterForProjection,
which is also more explicit.
The getGutter method was not API and is only used by the renderer.
Instead, only prevent default on handled pointerdown events. This makes
the `focus` condition work with interactions that involve dragging on
touch devices.
This brings canvas polygon hit detection in parity with WebGL, where an
unfilled polygon will not be hit detected hovering inside the polygon.

## Getting Started
## Getting Started
Use one of the following methods to use OpenLayers in your project:
Install the [`ol` package](https://www.npmjs.com/package/ol):
* For use with webpack, Rollup, Browserify, or other module bundlers, install the [`ol` package](https://www.npmjs.com/package/ol):
```
```
npm install ol
npm install ol
```
```
* If you just want to add a `<script>` tag to test things out, you can link directly to one of the full builds from [cdnjs](https://cdnjs.com/libraries/openlayers) (not recommended for production)
See the following examples for more detail on bundling OpenLayers with your application:
* Using [Rollup](https://github.com/openlayers/ol-rollup)
* Using [Webpack](https://github.com/openlayers/ol-webpack)
* Using [Parcel](https://github.com/openlayers/ol-parcel)
* Using [Browserify](https://github.com/openlayers/ol-browserify)
## IntelliSense support and type checking for VS Code
The `ol` package contains a `src/` folder with JSDoc annotated sources. TypeScript can get type definitions from these sources with a `jsconfig.json` config file in the project root:
```js
{
"compilerOptions":{
"checkJs":true,
// Point to the JSDoc typed sources when using modules from the ol package
"baseUrl":"./",
"paths":{
"ol":["node_modules/ol/src"],
"ol/*":["node_modules/ol/src/*"]
}
},
"include":[
"**/*.js",
"node_modules/ol/**/*.js"
]
}
```
Project template with this configuration: https://gist.github.com/9a7253cb4712e8bf38d75d8ac898e36c.
Note that the above only works when authoring in plain JavaScript. For similar configurations with a `tsconfig.json` in TypeScript projects, your mileage may vary.

##### The `setCenter`, `setZoom`, `setResolution` and `setRotation` methods on `ol/View` do not bypass constraints anymore
Previously, these methods allowed setting values that were inconsistent with the given view constraints.
This is no longer the case and all changes to the view state now follow the same logic:
target values are provided and constraints are applied on these to determine the actual values to be used.
##### Removal of the `constrainResolution` option on `View.fit`, `PinchZoom`, `MouseWheelZoom` and `ol/interaction.js`
The `constrainResolution` option is now only supported by the `View` class. A `View.setConstrainResolution` method was added as well.
Generally, the responsibility of applying center/rotation/resolutions constraints was moved from interactions and controls to the `View` class.
##### The view `extent` option now applies to the whole viewport
Previously, this options only constrained the view *center*. This behaviour can still be obtained by specifying `constrainCenterOnly` in the view options.
As a side effect, the view `rotate` method is gone and has been replaced with `adjustRotation` which takes a delta as input.
##### The view is constrained so only one world is visible
Previously, maps showed multiple worlds at low zoom levels. In addition, it used to be possible to pan off the north or south edge of the world. Now, the view is restricted to show only one world, and you cannot pan off the edge. To get the previous behavior, configure the `ol/View` with `multiWorld: true`.
##### Removal of deprecated methods
The `inherits` function that was used to inherit the prototype methods from one constructor into another has been removed.
The standard ECMAScript classes should be used instead.
The deprecated `getSnapToPixel` and `setSnapToPixel` functions from the `ImageStyle` class have been removed.
##### New internal tile coordinates
Previously, the internal tile coordinates used in the library had an unusual row order – the origin of the tile coordinate system was at the top left as expected, but the rows increased upwards. This meant that all tile coordinates within a tile grid's extent had negative `y` values.
Now, the internal tile coordinates used in the library have the same row order as standard (e.g. XYZ) tile coordinates. The origin is at the top left (as before), and rows or `y` values increase downward. So the top left tile of a tile grid is now `0, 0`, whereas it was `0, -1` before.
```
x, y values for tile coordinates
origin
*__________________________
| | | |
| 0, 0 | 1, 0 | 2, 0 |
|________|________|________|
| | | |
| 0, 1 | 1, 1 | 2, 1 |
|________|________|________|
| | | |
| 0, 2 | 1, 2 | 2, 2 |
|________|________|________|
```
This change should only affect you if you were using a custom `tileLoadFunction` or `tileUrlFunction`. For example, if you used to have a `tileUrlFunction` that looked like this:
```js
// before
functiontileUrlFunction(tileCoord){
constz=tileCoord[0];
constx=tileCoord[1];
consty=-tileCoord[2]-1;
// do something with z, x, y
}
```
You would now do something like this:
```js
// after
functiontileUrlFunction(tileCoord){
constz=tileCoord[0];
constx=tileCoord[1];
consty=tileCoord[2];
// do something with z, x, y
}
```
In addition (this should be exceedingly rare), if you previously created a `ol/tilegrid/WMTS` by hand and you were providing an array of `sizes`, you no longer have to provide a negative height if your tile origin is the top-left corner (the common case). On the other hand, if you are providing a custom array of `sizes` and your origin is the bottom of the grid (this is uncommon), your height values must now be negative.
##### Removal of the "vector" render mode for vector tile layers
If you were previously using `VectorTile` layers with `renderMode: 'vector'`, you have to remove this configuration option. That mode was removed. `'hybrid'` (default) and `'image'` are still available.
##### Removal of the "renderMode" option for vector layers
If you were previously using `Vector` layers with `renderMode: 'image'`, you have to remove this configuration option. Instead, use the new `ol/layer/VectorImage` layer with your `ol/source/Vector`.
##### New declutter behavior
If a map has more than one layer with `declutter` set to true, decluttering now considers all `Vector` and `VectorTile` layers, instead of decluttering each layer separately. Only `VectorImage` layers continue to be decluttered separately. The higher the z-index of a layer, the higher the priority of its decluttered items.
Within a layer, the declutter order has changed. Previously, styles with a lower `zIndex` were prioritized over those with a higher `zIndex`. Now the opposite order is used.
On vector layers, even if decluttered images or texts have a lower z-Index than polygons or lines, they will now be rendered on top of the polygons or lines. For vector tile layers, this was the case already in previous releases.
##### New `prerender` and `postrender` layer events replace old `precompose`, `render` and `postcompose` events
If you were previously registering for `precompose` and `postcompose` events, you should now register for `prerender` and `postrender` events on layers. Instead of the previous `render` event, you should now listen for `postrender`. Layers are no longer composed to a single Canvas element. Instead, they are added to the map viewport as individual elements.
##### New `getVectorContext` function provides access to the immediate vector rendering API
Previously, render events included a `vectorContext` property that allowed you to render features or geometries directly to the map. This is still possible, but you now have to explicitly create a vector context with the `getVectorContext` function. This change makes the immediate rendering API an explicit dependency if your application uses it. If you don't use this API, your application bundle will not include the vector rendering modules (as it did before).
Here is an abbreviated example of how to use the `getVectorContext` function:
```js
import{getVectorContext}from'ol/render';
// construct your map and layers as usual
layer.on('postrender',function(event){
constvectorContext=getVectorContext(event);
// use any of the drawing methods on the vector context
});
```
##### Layers can only be added to a single map
Previously, it was possible to render a single layer in two maps. Now, each layer can only belong to a single map (in the same way that a single DOM element can only have one parent).
##### The `OverviewMap` requires a list of layers.
Due to the constraint above (layers can only be added to a single map), the overview map needs to be constructed with a list of layers.
##### The `ol/Graticule` has been replaced by `ol/layer/Graticule`
Previously, a graticule was not a layer. Now it is. See the graticule example for details on how to add a graticule layer to your map.
##### `ol/format/Feature` API change
The `getLastExtent()` method, which was required for custom `tileLoadFunction`s in `ol/source/Vector`, has been removed because it is no longer needed (see below).
##### `ol/VectorTile` API changes
* Removal of the `getProjection()` and `setProjection()` methods. These were used in custom `tileLoadFunction`s on `ol/source/VectorTile`, which work differently now (see below).
* Removal of the `getExtent()` and `setExtent()` methods. These were used in custom `tileLoadFunction`s on `ol/source/VectorTile`, which work differently now (see below).
##### Custom tileLoadFunction on a VectorTile source needs changes
Previously, applications needed to call `setProjection()` and `setExtent()` on the tile in a custom `tileLoadFunction` on `ol/source/VectorTile`. The format's `getLastExtent()` method was used to get the extent. All this is no longer needed. Instead, the `extent` (first argument to the loader function) and `projection` (third argument to the loader function) are simply passed as `extent` and `featureProjection` options to the format's `readFeatures()` method.
Example for an old `tileLoadFunction`:
```js
function(tile,url){
tile.setLoader(function(){
fetch(url).then(function(response){
response.arrayBuffer().then(function(data){
varformat=tile.getFormat();
tile.setProjection(format.readProjection(data));
tile.setFeatures(format.readFeatures(data,{
// featureProjection is not required for ol/format/MVT
##### Drop of support for the experimental WebGL renderer
The WebGL map and layers renderers are gone, replaced by a `WebGLHelper` function that provides a lightweight,
low-level access to the WebGL API. This is implemented in a new `WebGLPointsLayer` which does simple rendering of large number
of points with custom shaders.
This is now used in the `Heatmap` layer.
The removed classes and components are:
*`WebGLMap` and `WebGLMapRenderer`
*`WebGLLayerRenderer`
*`WebGLImageLayer` and `WebGLImageLayerRenderer`
*`WebGLTileLayer` and `WebGLTileLayerRenderer`
*`WebGLVectorLayer` and `WebGLVectorLayerRenderer`
*`WebGLReplay` and derived classes, along with associated shaders
*`WebGLReplayGroup`
*`WebGLImmediateRenderer`
*`WebGLMap`
* The shader build process using `mustache` and the `Makefile` at the root
##### Removal of the AtlasManager
Following the removal of the experimental WebGL renderer, the AtlasManager has been removed as well. The atlas was only used by this renderer.
The non API `getChecksum` functions of the style is also removed.
##### Change of the behavior of the vector source's clear() and refresh() methods
The `ol/source/Vector#clear()` method no longer triggers a reload of the data from the server. If you were previously using `clear()` to refetch from the server, you now have to use `refresh()`.
The `ol/source/Vector#refresh()` method now removes all features from the source and triggers a reload of the data from the server. If you were previously using the `refresh()` method to re-render a vector layer, you should instead call `ol/layer/Vector#changed()`.
#### Other changes
##### Allow declutter in image render mode
It is now possible to configure vector tile layers with `declutter: true` and `renderMode: 'image'`. However, note that decluttering will be done per tile, resulting in labels and point symbols getting cut off at tile boundaries.
Until now, using both options forced the render mode to be `hybrid`.
##### Always load tiles while animating or interacting
`ol/PluggableMap` and subclasses no longer support the `loadTilesWhileAnimating` and `loadTilesWhileInteracting` options. These options were used to enable tile loading during animations and interactions. With the new DOM composition render strategy, it is no longer necessary to postpone tile loading until after animations or interactions.
### v5.3.0
#### The `getUid` function returns string
The `getUid` function from the `ol/util` module now returns a string instead of a number.
#### Attributions are not collapsible for `ol/source/OSM`
When a map contains a layer from a `ol/source/OSM` source, the `ol/control/Attribution` control will be shown with the `collapsible: false` behavior.
To get the previous behavior, configure the `ol/control/Attribution` control with `collapsible: true`.
### v5.2.0
#### Removal of the `snapToPixel` option for `ol/style/Image` subclasses
The `snapToPixel` option has been removed, and the `getSnapToPixel` and `setSnapToPixel` methods are deprecated.
The renderer now snaps to integer pixels when no interaction or animation is running to get crisp rendering. During interaction or animation, it does not snap to integer pixels to avoid jitter.
When rendering with the Immediate API, symbols will no longer be snapped to integer pixels. To get crisp images, set `context.imageSmoothingEnabled = false` before rendering with the Immediate API, and `context.imageSmoothingEnabled = true` afterwards.
### v5.1.0
#### Geometry constructor and `setCoordinates` no longer accept `null` coordinates
Geometries (`ol/geom/*`) now need to be constructed with valid coordinates (center for `ol/geom/Circle`) as first constructor argument. The same applies to the `setCoordinates()` (`setCenter()` for `ol/geom/Circle`) method.
### v5.0.0
#### 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.

### v4.6.0
#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`
#### Renamed `exceedLength` option of `ol.style.Text` to `overflow`
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 v5.0.1 release helps reduce bundle sizes for bundlers that support the `"sideEffects": "false"`option in `package.json`, and fixes website documentation regarding cdn locations and debug build which has been replaced by source maps.
## Fixes
* [#8341](https://github.com/openlayers/openlayers/pull/8341) - Set sideEffects: false flag ([@ahocevar](https://github.com/ahocevar))
* [#8342](https://github.com/openlayers/openlayers/pull/8342) - Fix links and description in quickstart tutorial ([@ahocevar](https://github.com/ahocevar))
* [#8371](https://github.com/openlayers/openlayers/pull/8371) - Skip rendering when there is no replay group ([@ahocevar](https://github.com/ahocevar))
The 5.1 release adds a few new features a handful of fixes. You should be able to upgrade without any additional work. See the one note below regarding `null` geometry coordinates.
We're working toward type checking with TypeScript. This will complete our move away from using the Closure Compiler for type checking and compilation. We're excited about the improved experience for application developers and will highlight some of the benefit in upcoming releases.
### Upgrade Notes
#### Geometry constructor and `setCoordinates` no longer accept `null` coordinates
Geometries (`ol/geom/*`) now need to be constructed with valid coordinates (center for `ol/geom/Circle`) as first constructor argument. The same applies to the `setCoordinates()` (`setCenter() for `ol/geom/Circle`) method.

The 5.2 release adds a few new features a handful of fixes, including regressions that were reported after the 5.1 release. You should be able to upgrade without any additional work. See the one note below regarding `snapToPixel` on `ol/style/Image` and subclasses.
We're still working toward type checking with TypeScript. Until that is complete, we apologize for some flwas in the online API documentation. We're excited about the improved experience for application developers when the effort is finished, and will highlight some of the benefit in upcoming releases.
### Upgrade Notes
#### Removal of the `snapToPixel` option for `ol/style/Image` subclasses
The `snapToPixel` option has been removed, and the `getSnapToPixel` and `setSnapToPixel` methods are deprecated.
The renderer now snaps to integer pixels when no interaction or animation is running to get crisp rendering. During interaction or animation, it does not snap to integer pixels to avoid jitter.
When rendering with the Immediate API, symbols will no longer be snapped to integer pixels. To get crisp images, set `context.imageSmoothingEnabled = false` before rendering with the Immediate API, and `context.imageSmoothingEnabled = true` afterwards.

We're continuing to work toward more complete type checking with TypeScript – based on JSDoc annotations in the source. The 5.3 release includes a number of bug fixes related to the type checking effort. In addition the release comes with a handful of new features and improved API reference docs.
### Upgrade Notes
#### The `getUid` function returns string
The `getUid` function from the `ol/util` module now returns a string instead of a number.
#### Attributions are not collapsible for `ol/source/OSM`
When a map contains a layer from a `ol/source/OSM` source, the `ol/control/Attribution` control will be shown with the `collapsible: false` behavior.
To get the previous behavior, configure the `ol/control/Attribution` control with `collapsible: true`.

## Why is zooming or clicking in the map off/inaccurate?
OpenLayers does not update the map when the container element is resized. This can be caused by progressive updates
to CSS styles or manually resizing the map. When that happens, any interaction will become inaccurate: the map would zoom in and out, and end up not being centered on the pointer. This makes it hard to do certain interactions, e.g. selecting the desired feature.
There is currently no built-in way to react to element's size changes, as [Resize Observer API](https://developer.mozilla.org/en-US/docs/Web/API/ResizeObserver) is only implemented in Chrome.
There is however an easy to use [polyfill](https://github.com/que-etc/resize-observer-polyfill):
This primer shows you how to put a simple map on a web page.

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.
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:
title: Basic project setup using NPM and Browserify
layout: doc.hbs

# Introduction
When going beyond modifying existing examples you might be looking for a way to setup your own code with dependency management together with external dependencies like OpenLayers.
This tutorial serves as a suggested project setup using NPM and Browserify for the most basic needs. There are several other options, and in particular you might be interested in a more modern one (ES2015) [using Webpack with OpenLayers](https://gist.github.com/tschaub/79025aef325cd2837364400a105405b8).
## 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 --save ol`.
At this point you can ask NPM to add required development dependencies by running
We will be using `cssify` to include the css definitions required by OpenLayers in our bundle. `watchify`, `http-server` and `uglify-js` are used to monitor for changes and to build into a minified bundle. `babelify` and `babel-plugin-transform-es2015-modules-commonjs` are used to make the `ol` package, which was created using ES2015 modules, work with CommonJS.
## Application code and index.html
Place your application code in `index.js`. Here is a simple starting point:
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 Browserify with OpenLayers</title>
<style>
#map{
width:400px;
height:250px;
}
</style>
</head>
<body>
<divid="map"></div>
<scriptsrc="bundle.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`:
Now to test your application open http://localhost:8080/ in your browser. `watchify` will update `bundle.js` whenever you change something. You simply need to reload the page in your browser to see the changes.
```
$ npm start
```
Note that `bundle.js` will contain your application code and all dependencies used in your application. From OpenLayers, it only contains the required components.
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 with
npm init
This will create a `package.json` file in your working directory. 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 `index.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 two additional lines in `package.json` you can introduce the commands `npm run build` and `npm start` to manually build your bundle and watch for changes, respectively. The final `package.json` with the two additional commands `"start"` and `"build"` should look like this:
```json
{
"name":"test",
"version":"1.0.0",
"description":"",
"main":"index.js",
"scripts":{
"test":"echo \"Error: no test specified\" && exit 1",
"start":"parcel index.html",
"build":"parcel build --public-url . index.html"
},
"author":"",
"license":"ISC"
}
```
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()`.
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()`.
The markup below could be used to create a `<div>` that contains your map.
The script below constructs a map that is rendered in the `<div>` above, using the `map` id of the element as a selector.
```js
import Map from 'ol/Map';
var map = new Map({target: 'map'});
```
```
## View
## View
`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.
The map is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of a `ol/View` instance.

center: [0, 0],
zoom: 2
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.

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.

var osmSource = new ol.source.OSM();
import OSM from 'ol/source/OSM';
var osmSource = OSM();
```
```
## Layer
## Layer
A layer is a visual representation of data from a `source`. OpenLayers has three basic types of layers: `ol.layer.Tile`, `ol.layer.Image` and `ol.layer.Vector`.
`ol.layer.Tile` is for layer sources that provide pre-rendered, tiled images in grids that are organized by zoom levels for specific resolutions.
A layer is a visual representation of data from a `source`. OpenLayers has four basic types of layers:
`ol.layer.Image` is for server rendered images that are available for arbitrary extents and resolutions.
* `ol/layer/Tile` - Renders sources that provide tiled images in grids that are organized by zoom levels for specific resolutions.
* `ol/layer/Image` - Renders sources that provide map images at arbitrary extents and resolutions.
`ol.layer.Vector` is for vector data that is rendered client-side.
* `ol/layer/Vector` - Renders vector data client-side.
* `ol/layer/VectorTile` - Renders data that is provided as vector tiles.
```js
```js
var osmLayer = new ol.layer.Tile({source: osmSource});
import TileLayer from 'ol/layer/Tile';
map.addLayer(osmLayer);
var osmLayer = new TileLayer({source: osmSource});
map.addLayer(osmLayer);
```
```
## Putting it all together
## Putting it all together
The above snippets can be combined into a single script that renders a map with a single tile layer:
The above snippets can be conflated to a self contained map configuration with view and layers:
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.
## 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.
