pamdice Updated: 31 January 2002 Table Of Contents NAME pamdice - slice a Netpbm image into many horizontally and/or vertically SYNOPSIS pamdice -outstem=filenamestem [-width=width] [-height=height] [-hoverlap=hoverlap] [-voverlap=voverlap] [-verbose] [file- name] 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 This program is part of Netpbm. pamdice reads a PAM, PBM, PGM, or PPM image as input and splits it horizontally and/or vertically into equal size pieces and writes them into separate files as the same kind of image. You can optionally make the pieces overlap. See the -outstem option for information on naming of the out- put files. The -width and -height options determine the size of the out- put pieces. pnmcat can rejoin the images. One use for this is to make pieces that take less computer re- sources than the whole image to process. For example, you might have an im- age so large that an image editor can't read it all into memory or process- es it very slowly. With pamdice, you can split it into smaller pieces, edit one a time, and then reassemble them. Another use for this is to print a large image in small print- er-sized pieces that you can glue together. ppmglobe does a similar thing; it lets you glue the pieces together into a sphere. 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 out- put 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 mul- tiple 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 mul- tiple of height pixels high. -hoverlap=hoverlap gives the horizontal overlap in pixels between output images. Each image in a row will overlap the previous one by hover- lap pixels. By default, there is no overlap. This option was new in Netpbm 10.23 (July 2004). -voverlap=voverlap gives the vertical overlap in pixels between output im- ages. Each row of images will overlap the previous row by voverlap pixels. By default, there is no overlap. This option was new in Netpbm 10.23 (July 2004). -verbose Print information about the processing to Standard Er- ror.
