This commit adds 'resize_gif()' function which extracts each frame, resize it and coalesces them again to form the resized GIF while preserving the duration of the GIF. I read some stackoverflow answers all of which were referring to BiggleZX's script (https://gist.github.com/BigglesZX/4016539) for working with animated GIF. I modified the script to fit to our usecase and did some manual testing but the function was failing for some specific GIFs and was not preserving the duration of animation. So I went ahead and read about GIF format itself as well as PIL's `GifImagePlugin` code and came up with this simple function which gets the worked done in a much cleaner way. I tested this function on a number of GIF images from giphy.com and it resized all of them correctly. Fixes: #9945. |
