SYNOPSIS pnmtorle [-h] [-v] [-a] [-o outfile] [pnmfile] DESCRIPTION This program is part of Netpbm(1). This program converts Netpbm image files into Utah RLE image files. You can include a transparency mask. If the input is a multiple image file, the output consists of several concatenated RLE images. The RLE file will contain either a three channel color image (24 bits) or a single channel grayscale image (8 bits) depending upon the pnm file depth. If a converted ppm is dis- played on an 8 bit display, the image must be dithered. In order to produce a better looking image (on 8 bit displays), it is recommended that the image be quantizing (to 8 bit mapped color) prior to its display. This may be done by piping the output of this program into the Utah mcut or rlequant utilities. We show an example of this later. OPTIONS -v This option will cause pnmtorle to operate in verbose mode. The header information is written to "stderr". Actually, there is not much header information stored in a Netpbm file, so this information is minimal. -h This option allows the header of the Netpbm image to be dumped to "stderr" without converting the file. It is equivalent to using the -v option except that no file conversion takes place. -a This option causes pnmtorle to include an transparency channel in the output image. The transparency channel is based on the image: Wherever a pixel is black, the cor- responding trasparency value is transparent. Everywhere else, the transparency value is fully opaque. -o outfile If you specify this option, pnmtorle writes the output to this file. If outfile is - or you don't specify -o, pnmtorle writes the output to Standard Output. pnmfile The name of the Netpbm image data file to be converted. If not specified, standard input is assumed. EXAMPLES pnmtorle -v file.ppm -o file.rle While running in verbose mode, convert file.ppm to RLE format and store resulting data in file.rle. pnmtorle -h file.pgm Dump the header information of the Netpbm file called file.pgm.
