Hi guys,
Is there a build-in method( in QPainter, for instance) that can help to create a clipped polygon?
I have a rect(scene rectangle) + polygon that is drawn on the scene. When the whole polygon is visible it draws background really fast, but when I zoom IN it draws very slowly;
I have already have line clip method, which increased the speed of redrawing, but now have to get a polygon clip.
Any idea?
Or maybe if no clipper' like method in Qt, do you know an open source C++ code implementing polygon clipping?
Thank you,
Kacper
