- GifClip
- -------
-
- Program to clip images in GIF files. Only one image in GIF file can be modified
- at a time. Neither image relative position to screen, nor screen sizes are
- modified (use GifPos for that).
-
- Usage:
- ------
-
- Usage: GifClip [-q] [-i Xmin Ymin Xmax Ymax] [-n n Xmin Ymin Xmax Ymax] [-h]
- GifFile
-
- If no GifFile is given, GifClip will try to read stdin for GIF file.

- Memory required:

- Options:
- --------
-
- 1. [-q] : quite mode. Default off on MSDOS, on on unix. Controls printout
- of running scan lines. Use -q- to turn off.
- 2. [-i Xmin Ymin Xmax Ymax] : Clip first image to the dimensions as specified
- by the 4 coordinates (Xmin Ymin Xmax Ymax) of a box clipping region.
- For example: '-i 11 22 33 44' will crop the box from top left [11,22]
- to bottom right [33,44] out of the first image.
- If the first parameter is bigger than third one (Xmin > Xmax) - they are
- swapped. Same for Y.
- Dimensions of cropped image must be confined to original image width and
- height. Note the clipped image include both min & max boundry, and image
- of width W can have coordinates 0 to W-1 (zero based).
- Only one of -i or -n can be specified.
- 3. [-n n Xmin Ymin Xmax Ymax] : same as -i above but for the nth image:
- '-n 1 11 22 33 44' is exactly the same as the example in -i. Only one of
- -i or -n can be specified.
- 4. [-h] : print one command line help, similar to Usage above.
