NAME

gifrotat - Program to rotate a GIF image by a specified angle.  

SYNOPSIS

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

DESCRIPTION

A program to rotate a GIF image by a specified angle.

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

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 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.
 

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.
