To be more clear... this to outside of loop: tmpImage = DrawingArea1.Grab().Image
this to inside of loop: c = tmpImage[x, y] But like Benoit said, it's not necessary in sync with DrawingArea internal buffer... depends on situation. I have used that kind of code with pictures, to gain more speed; tmpImage = SomePicture.Image Jussi 2009/4/22 Benoît Minisini <gam...@users.sourceforge.net>: >> hi, >> I need to get the color of point into drawingaera. >> I use "c = DrawingArea1.Grab().Image[x, y]" >> This works well, but for a Area of 512 x 512 points it needs more than 10 >> minutes >> How can I accelerate this function? >> >> kind regards >> Jürgen > > On X-Window, you don't have access to the pixel data of the buffer used by a > DrawingArea, so it will always be slow. > > To be fast, you must have an Image buffer and keep it in sync with the > DrawingArea internal buffer.
