Hi list, this is very basic, in fact so basic no one ever asked it seems :)
I need to correct the trapezoidal/keystone deformation of a video. The beamer I use can't correct enough, so I need to do that with GEM. I heard of a keystone library but could not find it. I tried various rotate/scale/translate without getting good enough results. So I thought I could have a polygon with a texture mapped on it, and the stretch the corners. The problem I have is that my patch is as follows: [pix_image test.png] | [pix_texture] | [circle 4] (The circle is used to make a mask so the video boundaries are round.) Adding a polygon after the circle does not seem to work. Any advice welcome. -- Charlot _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
