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.
