Example XSprite file #1
This is a small example XSprite file for testing XSprite programs. It contains one frame, a multiple colour image layer, a 50% alpha layer, and 3 active mask layers; 1 all on, 1 all off and 1 checkered.
This is the original file specification file that the developers of XSprite work from. A proper explanation of the format is provided at this site under 'Information', but this file is available if you so desire it.
