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 gifpos .SH USAGE .B 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. .SH MEMORY REQUIRED Line. .SH OPTIONS .IP [\-q] Quiet mode. Default off on MSDOS, on under UNIX. Controls printout of running scan lines. Use \-q\- to invert. .IP "[\-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. .IP "[\-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. .IP [\-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. .IP [\-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). .SH AUTHOR Gershon Elber Man page created by T.Gridel , originally written by Eric S. Raymond
