Converts LineString, MultiLineString, and LinearRing geometries into a MultiLineString by cutting them into parts no longer than the given distance along their length. All other geometry types will be converted to an empty MultiLineString.
Usage
Returns
LineString.cutLines(distances,maxError,proj)
Geometry
Argument
Type
Details
this:geometry
Geometry
Cuts the lines of this geometry.
distances
List
Distances along each LineString to cut the line into separate pieces, measured in units of the given proj, or meters if proj is unspecified.
maxError
ErrorMargin, default: null
The maximum amount of error tolerated when performing any necessary reprojection.
proj
Projection, default: null
Projection of the result and distance measurements, or EPSG:4326 if unspecified.
