       rletopnm	 -  convert  a Utah Raster Tools RLE image file	to a PNM image


       [--alphaout={alpha-filename,-}] [--headerdump|-h]



       All options may be abbreviated to their minimum unique abbreviation and
       options and arguments may be in any order.

       This program is part of Netpbm(1).

       rletopnm	 converts  Utah	 Raster	 Toolkit  RLE image files to 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), True-
       color (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.

	      rletopnm	 creates  a PGM	(portable graymap) file	containing the
	      transparency channel values in the input image.	If  the	 input
	      image  doesn't  contain an transparency channel, the alpha-file-
	      name file	contains all zero (transparent)	 transparency  values.
	      If  you  don't  specify --alphaout, rletopnm does	not generate a
	      transparency file, and if	the input  image  has  a  transparency
	      channel, rletopnm	simply discards	it.

	      If  you specify -	as the filename, rletopnm writes the transpar-
	      ency output to Standard Output and discards the image.

	      See pamcomp(1) for one way to use	the transparency output	file.

	      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.

	      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.

       o      While running in verbose mode, convert lenna.rle to  PPM	format
	      and store	the resulting image as lenna.ppm:

		  rletopnm --verbose lenna.rle >lenna.ppm

       o      Dump the header information of the RLE file called file.rle:

		  rletopnm --headerdump	file.rle

       o      Convert  RLE file	dart.rle to PPM	format as dart.ppm.  Store the
	      transparency channel of dart.rle as dartalpha.pgm	 (if  dart.rle
	      doesn't  have  a transparency channel, store a fully transparent
	      transparency mask	as dartalpha.pgm):

		  rletopnm --alphaout=dartalpha.pgm dart.rle >dart.ppm
