rletopnm

       file.

SYNOPSIS
       rletopnm  [--alphaout={alpha-filename,-}]   [--headerdump|-h]   [--ver-
       bose|-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  con-
              tains 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 out-
              put 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
