-OpenLayers. ConsoleThe OpenLayers.Console namespace is used for debugging and error logging. If the Firebug Lite (../Firebug/firebug.js) is included before this script, calls to OpenLayers.Console methods will get redirected to window.console. This makes use of the Firebug extension where available and allows for cross-browser debugging Firebug style. NoteNote that behavior will differ with the Firebug extention and Firebug Lite. Most notably, the Firebug Lite console does not currently allow for hyperlinks to code or for clicking on object to explore their properties. Summary
log
Log an object in the console. The Firebug Lite console logs string representation of objects. Given multiple arguments, they will be cast to strings and logged with a space delimiter. If the first argument is a string with printf-like formatting, subsequent arguments will be used in string substitution. Any additional arguments (beyond the number substituted in a format string) will be appended in a space- delimited line. Examples// Firebug Lite logs someObject.toString() Parameters

Prints an interactive stack trace of JavaScript execution at the point where it is called. The stack trace details the functions on the stack, as well as the values that were passed as arguments to each function. You can click each function to take you to its source in the Script tab, and click each argument value to inspect it in the DOM or HTML tabs.

-OpenLayers. LayerSummary
gutter{Integer} Determines the width (in pixels) of the gutter around image tiles to ignore. By setting this property to a non-zero value, images will be requested that are wider and taller than the tile size by a value of 2 x gutter. This allows artifacts of rendering at tile edges to be ignored. Set a gutter value that is equal to half the size of the widest symbol that needs to be displayed. Defaults to zero. Non-tiled layers always have zero gutter.

-
- OpenLayers. Tile. ImageConstructor for a new OpenLayers.Tile.Image instance. Parameters
-
-
-
-
-
-
-
- checkImgURL
Make sure that the image that just loaded is the one this tile is meant to display, since panning/zooming might have changed the tile’s URL in the meantime. If the tile URL did change before the image loaded, set the imgDiv display to ‘none’, as either (a) it will be reset to visible when the new URL loads in the image, or (b) we don’t want to display this tile after all because its new bounds are outside our maxExtent. This function should no longer be neccesary with the improvements to Grid.js in OpenLayers 2.3. The lack of a good isEquivilantURL function caused problems in 2.2, but it’s possible that with the improved isEquivilant URL function, this might be neccesary at some point.

+ OpenLayers. Tile. ImageConstructor for a new OpenLayers.Tile.Image instance. Parameters
+
+
+
+
+
+
+
+ checkImgURL
Make sure that the image that just loaded is the one this tile is meant to display, since panning/zooming might have changed the tile’s URL in the meantime. If the tile URL did change before the image loaded, set the imgDiv display to ‘none’, as either (a) it will be reset to visible when the new URL loads in the image, or (b) we don’t want to display this tile after all because its new bounds are outside our maxExtent. This function should no longer be neccesary with the improvements to Grid.js in OpenLayers 2.3. The lack of a good isEquivilantURL function caused problems in 2.2, but it’s possible that with the improved isEquivilant URL function, this might be neccesary at some point. See discussion in the thread at http://openlayers.org- /pipermail- /dev- /2007-January- /000205.html @private |
