Hi all, can someone tell me how to undraw/remove a polypolygon from a canvas? I found "CompositeOp" of "CanvasGraphic" and thought I could just set it to clear ( setCompositeOp( cppcanvas::CanvasGraphic::CLEAR ); ) before drawing and then just redraw the same polypolygon. But it does not work. I just want to undraw a painted polypolygon in aoo-trunk/main/slideshow/source/engine/slide/userpaintoverlay.cxx. I also tried to draw some polpolygons with alpha set to different values but they all look the same. (All drawn with 100% alpha) drawing a polypolygon with alpha set to 50 (alpha did not work for me): pPolyPoly->setStrokeWidth(50); pPolyPoly->setRGBALineColor( ::cppcanvas::makeColor( 100, 10, 10, 10 ) ); pPolyPoly->draw(); --------------------------------------------- Der perfekte Zeitpunkt seinen Gasversorger zu wechseln: http://www.anpa.de/index.php?action=gasvergleich
