RLETOPPM(1) 1 (July 20, 1990) RLETOPPM(1)
NAME
rletoppm - convert a Utah RLE image file into a PBMPLUS/ppm
image file.
SYNOPSIS
rletoppm [ -h ] [ -v ] [ -p ] [ infile ]
DESCRIPTION
This program converts Utah RLE(5) image files into PBMPLUS
full-color (ppm) image files. Rletoppm will handle four
types of RLE files: Grayscale (8 bit data, no color map),
Pseudocolor (8 bit data with a color map), Truecolor (24 bit
data with color map), and Directcolor (24 bit data, no color
map). Since the orgins for the RLE and PBMPLUS image file
formats are in different locations, this program
automatically "flips" the image when converting.
OPTIONS
-v This option will cause rletoppm to operate in verbose
mode. Header information is printed to "stderr".
-h This option allows the header of the RLE file to be
dumped to "stderr" without converting the file. It is
equivalent to using the -v option except that no file
conversion takes place.
-p This option will output the ppm data in the "plain"
format (P3), instead of the default "raw bits" format
(P6). The plain format is more readable, but takes up
more space.
infile
The input will be read from this file. If infile is
"-" or is not specified, the input will be read from
the standard input stream. The resulting PBMPLUS/ppm
data will be sent to "stdout".
EXAMPLES
rletoppm-v lenna.rle >lenna.ppm
While running in verbose mode, convert lenna.rle to
PBMPLUS/ppm format and store resulting data in
lenna.ppm.
rletoppm-h test.rle
Dump the header information of the RLE file called
test.rle.
rletoppm-p test.rle >lenna.ppm
Convert lenna.rle to PBMPLUS/ppm plain (P3) format and
store in lenna.ppm.
