gifclip - A program to clip images in GIF files. Only one image in a
GIF file can be modified at a time. Neither the image position on
screen nor the screen size is modified (use <a
gifclip [-q] [-i Xmin Ymin Xmax Ymax] [-n n Xmin Ymin Xmax Ymax] [-c]
If no gif-file is given, GifClip will try to read a GIF file from
Quiet mode. Default off on MSDOS, on under UNIX. Controls
printout of running scan lines. Use -q- to invert.
[-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.
The dimensions of the clipped image must be confined to original
image width and height. Note the clipped image includes both
the min & max boundary; an image of width W can have coordinates
0 to W-1 (zero based).
Only one of -i or -n can be specified.
[-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
Complement. This removes horizontal and/or vertical bands of
the image. For example ‘-c -i 638 3 658 13’ would remove a
horizontal band 11 pixels deep beginning at raster line 3, and a
vertical band 21 pixels right beginning at pixel 658.
Print one line of command line help, similar to Usage above.
Note: all coordinates are 0-based --- the top left corner is (0,
