Methods
-
applyTransform(transformFn)
src/ol/geom/simplegeometry.js, line 256 -
Apply a transform function to each coordinate of the geometry. The geometry is modified in place. If you do not want the geometry modified in place, first
clone()it and then use this function on the clone.Name Type Description transformFnol.TransformFunction Transform.
-
Increases the revision counter and dispatches a 'change' event.
-
Dispatches an event and calls all listeners listening for events of this type. The event parameter can either be a string or an Object with a
typeproperty.Name Type Description eventObject | ol.events.Event | string Event object.
-
Gets a value.
Name Type Description keystring Key name.
Returns:
Value.
-
Return the closest point of the geometry to the passed point as
coordinate.Name Type Description pointol.Coordinate Point.
closestPointol.Coordinate Closest point.
Returns:
Closest point.
-
Get the extent of the geometry.
Name Type Description extentol.Extent Extent.
Returns:
extent Extent.
-
Return the first coordinate of the geometry.
Returns:
First coordinate.
-
Get a list of object property names.
Returns:
List of property names.
-
Return the last coordinate of the geometry.
Returns:
Last point.
-
Return the
layoutof the geometry.Returns:
Layout.
-
Get an object of all property names and values.
Returns:
Object.
-
Get the version number for this object. Each time the object is modified, its version number will be incremented.
Returns:
Revision.
-
Returns true if this geometry includes the specified coordinate. If the coordinate is on the boundary of the geometry, returns false.
Name Type Description coordinateol.Coordinate Coordinate.
Returns:
Contains coordinate.
-
on(type, listener, opt_this){ol.EventsKey|Array.<ol.EventsKey>} inherited
src/ol/observable.js, line 99 -
Listen for a certain type of event.
Name Type Description typestring | Array.<string> The event type or array of event types.
listenerfunction The listener function.
thisObject The object to use as
thisinlistener.Returns:
Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.
-
once(type, listener, opt_this){ol.EventsKey|Array.<ol.EventsKey>} inherited
src/ol/observable.js, line 124 -
Listen once for a certain type of event.
Name Type Description typestring | Array.<string> The event type or array of event types.
listenerfunction The listener function.
thisObject The object to use as
thisinlistener.Returns:
Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.
-
Rotate the geometry around a given coordinate. This modifies the geometry coordinates in place.
Name Type Description anglenumber Rotation angle in radians.
anchorol.Coordinate The rotation center.
-
Scale the geometry (with an optional origin). This modifies the geometry coordinates in place.
Name Type Description sxnumber The scaling factor in the x-direction.
synumber The scaling factor in the y-direction (defaults to sx).
anchorol.Coordinate The scale origin (defaults to the center of the geometry extent).
-
Sets a value.
Name Type Description keystring Key name.
value* Value.
silentboolean Update without triggering an event.
-
Sets a collection of key-value pairs. Note that this changes any existing properties and adds new ones (it does not remove any existing properties).
Name Type Description valuesObject.<string, *> Values.
silentboolean Update without triggering an event.
-
Create a simplified version of this geometry. For linestrings, this uses the the Douglas Peucker algorithm. For polygons, a quantization-based simplification is used to preserve topology.
Name Type Description tolerancenumber The tolerance distance for simplification.
Returns:
A new, simplified version of the original geometry.
-
Transform each coordinate of the geometry from one coordinate reference system to another. The geometry is modified in place. For example, a line will be transformed to a line and a circle to a circle. If you do not want the geometry modified in place, first
clone()it and then use this function on the clone.Name Type Description sourceol.ProjectionLike The current projection. Can be a string identifier or a
ol.proj.Projectionobject.destinationol.ProjectionLike The desired projection. Can be a string identifier or a
ol.proj.Projectionobject.Returns:
This geometry. Note that original geometry is modified in place.
-
translate(deltaX, deltaY)
src/ol/geom/simplegeometry.js, line 308 -
Translate the geometry. This modifies the geometry coordinates in place. If instead you want a new geometry, first
clone()this geometry.Name Type Description deltaXnumber Delta X.
deltaYnumber Delta Y.
-
Unlisten for a certain type of event.
Name Type Description typestring | Array.<string> The event type or array of event types.
listenerfunction The listener function.
thisObject The object which was used as
thisby thelistener. -
Unsets a property.
Name Type Description keystring Key name.
silentboolean Unset without triggering an event.
