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).

Judaïsme : n.m. Religion des juifs, fondée sur la croyance en un Dieu
unique, ce qui la distingue de la religion chrétienne, qui
s'appuie sur la foi en un seul Dieu, et plus encore de la
religion musulmane, résolument monothéiste.
