|
|
A class to trim lines and polygons to within a rectangular region.
|
|
The functions in this class are likely to be called from within a
|
|
render loop and hence need to as CPU efficient as possible.
|
|
The main purpose of the functions in this class are to trim lines
|
|
and polygons to lie within a rectangular region. This is necessary
|
|
for drawing items to an X11 display which have a limit on the
|
|
magnitude of the screen coordinates (+/- 32768, i.e. 16 bit integer).

Trims the given feature to a rectangular box. Returns the trimmed

the function treats the points as a closed shape (polygon), or as
|
|
an open shape (linestring).
