NAME
       gifrotat - A program to rotate a GIF image by a specified angle.

USAGE
       gifrotat -a Angle [-q] [-s Width Height] [-h] gif-file

       If no gif-file is given, GifRotat will try to read a GIF file from stdin.

MEMORY REQUIRED
       Screen (of source image).

OPTIONS
       -a Angle

	       Specifies the angle to rotate in degrees with respect to the X (horizontal) axis.

       [-q]

	       Quiet mode.  Defaults off on MSDOS, on under UNIX.  Controls printout of running scan lines. Use -q- to invert.

       [-s Width Height]

	       Since  the  rotated  image  will have the same image size as the original, some parts of the image will by clipped out and lost. By
	      specifying a (bigger) size explicitly using the `-s' option, these parts may be saved.

       [-h]

	       Print one line of command line help, similar to Usage above.

NOTES
       The image is rotated around its center.	No filtering is performed on the output, which have the same color map	as  the  input.   This	is
       mainly  since  filtering would require color quantization which is very memory/time intensive and out of MSDOS memory limits even for small
       images.
