GIFROTAT(1)                  GIFLIB Documentation                  GIFROTAT(1)

NAME
       gifrotat - rotate a GIF image by a specified angle.

SYNOPSIS
       gifrotat [-v] -a angle [-s width height] [-h] [gif-file]

OPTIONS
       -a Angle
           Specifies the angle to rotate in degrees with respect to the X
           (horizontal) axis.

       -v
           Verbose mode (show progress). Enables printout of running scan
           lines.

       -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
           specifing 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.

       If no GIF file is given, gifrotat will try to read a GIF file from
       stdin.

NOTES
       The image is rotated around its center. No filtering is performed on
       the output, which has the same color map as the input.
