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.
