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
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.
[-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).
