applyApply a transform function to the coordinates of the geometry.

If you do not want the geometry modified in place, first clone()

linestring and 1 is the end.

Coordinate of the interpolated point.
Returns the coordinate at m

such coordinate exists.
extrapolate
controls extrapolation beyond the range of Ms in the
MultiLineString. If extrapolate
is true
then Ms less than the first

Create a simplified version of this geometry. For linestrings, this uses the Douglas Peucker algorithm. For polygons, a quantization-based simplification is used to preserve topology.
The tolerance distance for simplification.
A new, simplified version of the original geometry.
Abstract
simplifyTransform 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.
