Convert input to normal map.
-clamp Clamp wrapping mode (default).
-repeat
Repeat wrapping mode.
-nomips
Disable mipmap generation.

RLETOPNM(1) General Commands Manual RLETOPNM(1)NAME
rletopnm - convert a Utah Raster Tools RLE image file into a PNM image file.
SYNOPSIS
rletopnm [--alphaout={alpha-filename,-}] [--headerdump|-h] [--verbose|-v] [--plain|-p] [rlefile|-]
All options may be abbreviated to their minimum unique abbreviation and options and arguments may be in any order.
DESCRIPTION
This program converts Utah Raster Toolkit RLE image files into PNM image files. rletopnm handles 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). rletopnm generates a PPM file for all these cases except for the Grayscale file, for which rletopnm generates a PGM file.
rlefile is the RLE input file. If it is absent or -, the input comes from Standard Input.
OPTIONS --alphaout=alpha-filename
rletopnm creates a PGM (portable graymap) file containing the alpha channel values in the input image. If the input image doesn't
contain an alpha channel, the alpha-filename file contains all zero (transparent) alpha values. If you don't specify --alphaout,
rletopnm does not generate an alpha file, and if the input image has an alpha channel, rletopnm simply discards it.
If you specify - as the filename, rletopnm writes the alpha output to Standard Output and discards the image.
See pnmcomp(1) for one way to use the alpha output file.
--verbose
This option causes rletopnm to operate in verbose mode. It prints messages about what it's doing, including the contents of the RLE
image header, to Standard Error.
--headerdump
This option causes rletopnm to operate in header dump mode. It prints the contents of the RLE image header to Standard Error, but
does not produce any other output.
--plain
This option causes the PNM output file to be in the "plain" (text) format, instead of the default "raw" (binary) format. See ppm(5)
and pgm(5) for details on the difference.
EXAMPLES
rletopnm --verbose lenna.rle >lenna.ppm
While running in verbose mode, convert lenna.rle to PPM format and store the resulting image as lenna.ppm.
rletopnm --headerdump file.rle
Dump the header information of the RLE file called file.rle.
rletopnm --alphaout=dartalpha.pgm dart.rle >dart.ppm
Convert RLE file dart.rle to PPM format as dart.ppm. Store the alpha channel of dart.rle as dartalpha.pgm (if dart.rle doesn't have
an alpha channel, store a fully transparent alpha mask as dartalpha.pgm).
