NAME

       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 href="gifpos.html">gifpos

USAGE

       gifclip [-q] [-i Xmin Ymin Xmax Ymax] [-n n Xmin Ymin Xmax Ymax] [-c] [-h] gif-file

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

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

               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 be specified.

       [-c]

               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.

       [-h]

               Print one line of command line help, similar to Usage above.

              Note: all coordinates are 0-based --- the top left corner is (0, 0).
