gifrotat 1 GIFLIB GIFLIB Documentation
gifrotat rotate a GIF image by a specified angle.
`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.
