Class: Geometry

Methods

getClosestPoint(point, opt_closestPoint){module:ol/coordinate~Coordinate}

geom/Geometry.js, line 93

Return the closest point of the geometry to the passed point as coordinate.

Name	Type	Description
point	module:ol/coordinate~Coordinate	Point.
closestPoint	module:ol/coordinate~Coordinate	Closest point.

Returns:

Closest point.

getExtent(opt_extent){module:ol/extent~Extent}

geom/Geometry.js, line 124

Get the extent of the geometry.

Name	Type	Description
extent	module:ol/extent~Extent	Extent.

Returns:

extent Extent.

intersectsCoordinate(coordinate){boolean}

geom/Geometry.js, line 106

Returns true if this geometry includes the specified coordinate. If the coordinate is on the boundary of the geometry, returns false.

Name	Type	Description
coordinate	module:ol/coordinate~Coordinate	Coordinate.

Returns:

Contains coordinate.

rotate(angle, anchor)

geom/Geometry.js, line 140

Rotate the geometry around a given coordinate. This modifies the geometry coordinates in place.

Name	Type	Description
angle	number	Rotation angle in radians.
anchor	module:ol/coordinate~Coordinate	The rotation center.

scale(sx, opt_sy, opt_anchor)

geom/Geometry.js, line 153

Scale the geometry (with an optional origin). This modifies the geometry coordinates in place.

Name	Type	Description
sx	number	The scaling factor in the x-direction.
sy	number	The scaling factor in the y-direction (defaults to sx).
anchor	module:ol/coordinate~Coordinate	The scale origin (defaults to the center of the geometry extent).

simplify(tolerance){module:ol/geom/Geometry~Geometry}

geom/Geometry.js, line 176

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
tolerance	number	The tolerance distance for simplification.

Returns:

A new, simplified version of the original geometry.

transform(source, destination){module:ol/geom/Geometry~Geometry}

geom/Geometry.js, line 239

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
source	module:ol/proj~ProjectionLike	The current projection. Can be a string identifier or a module:ol/proj/Projection~Projection object.
destination	module:ol/proj~ProjectionLike	The desired projection. Can be a string identifier or a module:ol/proj/Projection~Projection object.

Returns:

This geometry. Note that original geometry is modified in place.

translate(deltaX, deltaY)

geom/Geometry.js, line 162

Translate the geometry. This modifies the geometry coordinates in place.

Name	Type	Description
deltaX	number	Delta X.
deltaY	number	Delta Y.
