Otherwise global color table applies to all frames irrespective of whether additional colors comes in play that require a redefined palette. Still a maximum of 256 color per frame, obviously.

A sort of header at the start of each image. Specifies duration and transparancy. Dispose ------- * 0 - No disposal specified. * 1 - Do not dispose. The graphic is to be left in place. * 2 - Restore to background color. The area used by the graphic must be restored to the background color. * 3 - Restore to previous.

Returns a two-element tuple containing the cropped image and an x-y tuple. Calculating the subrectangles takes extra time, obviously. However, if the image sizes were reduced, the actual writing of the GIF goes faster. In some cases applying this method produces a GIF faster. rr\r@rrrA)rr) rFrWr(absrBsumZargwherervr) r4rHprevdiffXYZx0x1Zy0y1r r rr^s     zGifWriter.getSubRectanglecCst|d}|dkr:d}|d}t||}|j||d}nB|dkrp|dkrV|d}n |d}|j||d }n td ||S) zConvert image to Paletted PIL image.
