NAME
gifpos - A program to change GIF screen size and/or reposition images. No test is made to make sure changes will generate valid GIF files (i.e. images are still confined to screen etc.) USAGE
gifpos [-q] [-s Width Height] [-i Left Top] [-n n Left Top] [-h] gif-file If no gif-file is given, GifPos will try to read a GIF file from stdin. MEMORY REQUIRED
Line. OPTIONS
[-q] Quiet mode. Default off on MSDOS, on under UNIX. Controls printout of running scan lines. Use -q- to invert. [-s Width Height] Set the new screen dimensions, so for example `-s 1000 800' will set screen to width of 1000 and height of 800. [-i Left Top] set image relative to screen position, so for example `-i 100 80' will set image left position to 100 and top position to 80. This sets the position of the first image only. [-n n Left Top] set image n relative to screen position, so for example '-n 3 100 80' will set the third image position as in 2. [-h] Print one line of command line help, similar to Usage above.
