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.
