Dynamically allocates enough memory to hold all the image internally. One byte per pixel is always allocated, so a little bit more than width*height (of screen, not image) bytes are required. Reads all the image in. Interlaced images are read in correctly, although they are displayed sequentially. Display first image using the defaults as set by the command line option. Goes to interactive mode. For a full description of the interactive mode see below. If no GIF is given, gif2bgi will try to read a GIF file from stdin. OPTIONS
Interactive modeOnce the image is displayed, the gif2bgi program goes into interactive mode which recognizes the following commands:
BUGSFor some reason I could not figure out, on my ATI wonder card, int 10h call 10h (AH = AL = 10h) to set the color registers sometimes result with wrong colors. Direct access of the card registers gives correct results.NOTESThis program is useless in a Unix environment and is not normally built there.No color quantization is used in this program; thus, if a GIF image has more colors than the BGI driver support, this program will abort. This driver is optimized for drivers with one byte per pixel (256 colors) and will run MUCH faster on such drivers.
