Only one image in a GIF file can bemodified at a time.  Neither the image position on screen nor the screen sizeis modified (use <a href="gifpos.html">gifpos</a> for that).<P><H1>Usage:</H1><pre>gifclip [-q] [-i Xmin Ymin Xmax Ymax] [-n n Xmin Ymin Xmax Ymax] [-c] [-h] gif-file</pre>If no gif-file is given, GifClip will try to read a GIF file from stdin.<P><H1>Memory required:</H1>Line.<H1>Options:</H1><DL><DT> [-q]<DD> Quiet mode.  Default off on MSDOS, on under UNIX.  Controls printout   of running scan lines.  Use -q- to invert.<P><DT> [-i Xmin Ymin Xmax Ymax]<DD> Clip first image to the dimensions as specified   by the 4 coordinates (Xmin Ymin Xmax Ymax) of a box clipping region.<P>   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.<P>   If the first parameter is bigger than third one (Xmin > Xmax) they are   swapped.  Same for Y.<P>   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).<P>   Only one of -i or -n can be specified.<P><DT> [-n n Xmin Ymin Xmax Ymax]<DD> 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.<P><DT> [-c]<DD> 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.<P><DT> [-h]<DD> Print one line of command line help, similar to Usage above.<P></DL>Note: all coordinates are 0-based --- the top left corner is (0, 0).<P><H1>Author:</H1>Gershon Elber<HR><ADDRESS>Eric S.
