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. The decoder is required to restore the area overwritten by the graphic with what was there prior to rendering the graphic. * 4-7 -To be defined. s!rArrkdg?rz)chrrlrRr)r4r6rKrwr r rrrs zGifWriter.getGraphicsControlExtc Cs|jdkr |dfS|j}t||}|jdkr|d}t|d}t|d}|jrR|jrRt|dt|dd}}t|dt|dd}} nd\}}d\}} ||| ||f||ffS)arCalculate the minimal rectangle that need updating. 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]rArrrB)rr) rGrXr(absrCsumZargwherervr) r4rIprevdiffXYZx0x1Zy0y1r r rr_s     zGifWriter.getSubRectanglecCst|d}|dvrd}|d}t||}|j||d}|S|dvr:|dkr,|d}n|d}|j||d }|Std |) zConvert image to Paletted PIL image.
