ppmrainbow - Generate a rainbow SYNOPSIS
ppmrainbow [-width=number] [-height=number] [-tmpdir=directory] [-verbose] color ... All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one to designate an option. You may use either white space or equals signs between an option name and its value. DESCRIPTION
ppmrainbow generates a PPM image that fades from one color to another to another from left to right, like a rainbow. The colors are those you specify on the command line, in that order. The first color is added again on the right end of the image. If you want a vertical or other non-horizontal rainbow, run the output through pnmrotate. One use for such a rainbow is to compose it with another image under an alpha mask in order to add a rainbow area to another image. In fact, you can make rainbow-colored text by using pbmtext, pnmcomp, and ppmrainbow. OPTIONS
-width number The width in pixels of the output image. Default is 600. -height number The height in pixels of the output image. Default is 8. -tmpdir The directory specification of the directory ppmrainbow is to use for temporary files. Default is the value of the TMPDIR environment variable, or /tmp if TMPDIR is not set. -verbose Print the "commands" (invocations of other Netpbm programs) that ppmrainbow uses to create the image.

pamdice - slice a Netpbm image into many horizontally and/or vertically SYNOPSIS
pamslice -outstem=filenamestem [-width=width] [-height=height] [-verbose] [filename] You can use the minimum unique abbreviation of the options. You can use two hyphens instead of one. You can separate an option name from its value with white space instead of an equals sign. DESCRIPTION
Reads a PAM, PBM, PGM, or PPM image as input. Splits it horizontally and/or vertically into equal size pieces and writes them into sepa- rate files as the same kind of image. See the -outstem option for information on naming of the output files. The -width and -height options determine the size of the output pieces. pnmcat can rejoin the images. OPTIONS
-outstem=filenamestem This option determines the names of the output files. Each output file is named filenamestem_y_x.type where filenamestem is the value of the -outstem option, x and y are the horizontal and vertical locations, respectively, in the input image of the output image, zero being the leftmost and top, and type is .pbm, .pgm, .ppm, or .pam, depending on the type of image. -width=width gives the width in pixels of the output images. The rightmost pieces are smaller than this if the input image is not a multiple of width pixels wide. -height=height gives the height in pixels of the output images. The bottom pieces are smaller than this if the input image is not a multiple of height pixels high. -verbose Print information about the processing to Standard Error. SEE ALSO
