gifclip(1) General Commands Manual gifclip(1) 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). AUTHOR

text2gif(1) General Commands Manual text2gif(1) NAME
text2gif - A program to generate GIF images out of regular text. Text can be one line or multi-line, and is converted using 8 by 8 fixed font. USAGE
text2gif [-q] [-s ClrMapSize] [-f FGClr] [-c R G B] [-t Text ] [-h] This program reads stdin if no text is provided on the command line (-t), and will dump the created GIF file to stdout. MEMORY REQUIRED
Line. OPTIONS
[-q] Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout of running scan lines. Use -q- to invert. [-s ClrMapSize] Explicitly defines the size of the color map of the resulting gif image. Usually the image will be bicolor with fg as color 1, unless [-f] is explicitly given in case the color map size will be big enough to hold it. However it is sometimes convenient to set the color map size to certain size while the fg color is small mainly so this image may be merged with another (images must match color map size). [-f FG] Select foreground index (background is always 0). By default it is one and therefore the image result is bicolored. if FG is set to n then color map will be created with 2^k entries where 2^k > n for minimum k, assuming k <= 8. This color map will be all zeros except this forground index. This option is useful if this text image should be integrated into other image colormap using their colors. [-c R G B] The color to use as the foreground color. White by default. [-t "Text"] One line of text can be provided on the command line. Note you must encapsulate the Text within quotes if it has spaces (The quotes themselves are not treated as part of the text). If no -t option is provided, stdin is read until end of file. [-h] Print one line command line help, similar to Usage above. NOTES
There is a hardcoded limit of 100 the number of lines. AUTHOR
