I would like to announce the beta release of a general polygon clipper
library (in C). The clipper can perform union, difference and
intersection operations on arbitrary polygon sets (multibpe contours,
holes, convex, self-intersecting etc).
There are a number of known bugs which will hopefully be remedied in
later releases. However, the clipper should work well for all but a few
pathological cases, and will hopefully be of use to the graphics
community in its present state.
The clipper may be found at:
