Hi! I have found a bug in how PIL handles animated GIFs. The GIF in question contains several frames, where each new frame only overwrites parts of the previous frame. Unless I explicitly ask PIL to load/show each frame, PIL completely skips previous frames which means that the extracted image will contain uninitialized data.
Steps to reproduce: Image: http://dl.dropbox.com/u/14498565/image0006.gif #Will show uninitialized data from PIL import Image i = Image.open("image0006.gif") i.seek(1) j = i.convert("RGBA") j.show() #Seems to fix problem with uninitialized data by forcing PIL to load the previous frame #(Works most of the time, but does not seem completely reliable. The image buffer is probably uninitialized and #simply reused which can work if lucky.) from PIL import Image i = Image.open("image0006.gif") i.load() i.seek(1) j = i.convert("RGBA") j.show() Best regards, //Leo _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
