RLATORLE(1)							   RLATORLE(1)

NAME
       rlatorle	 -  convert  a Wavefront "rla" or "rlb" image file into an RLE
       image file.

SYNOPSIS
       rlatorle [ -b ] [ -h ] [ -v ] [ -m ] [ -o outfile ] [ infile.rla ]

DESCRIPTION
       This program converts Wavefront image files (rla or rlb	formats)  into
       Utah  RLE(5) image files.  Wavefront image files store RGB data as well
       as a matte channel.  They also define a "bounding box" containing  non-
       background  pixels  which is in many cases smaller than the total image
       area.  Only this non-background area is run length encoded.  When  con‐
       verting to an RLE file, the matte channel is stored as an alpha channel
       and the "bounding box" dimensions are ignored.  It is for  this	reason
       that  in	 general  the  RLE version of the file will be larger than its
       Wavefront counterpart.

       The RLE file will contain a "true color" image (24  bits).   These  RLE
       files  may  then	 be  viewed using any RLE image viewer.	 When they are
       displayed on an 8 bit display, the image will 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  dis‐
       play.   This  may be done by piping the output of this program into the
       Utah mcut(1) or rlequant(1) utilities.  An example  of  this  is	 shown
       later.

OPTIONS
       -b     This  option  will  cause	 rlatorle  to convert from a Wavefront
	      "rlb" image rather than use the default "rla" conversion.

       -v     This option will cause rlatorle to operate in verbose mode.  The
	      header information is written to "stderr".

       -h     This  option  allows  the	 header	 of  the wavefront image to be
	      dumped to "stderr" without converting the file.  It  is  equiva‐
	      lent to using the -v option except that no file conversion takes
	      place.

       -m     This option will cause rlatorle to ignore the RGB data  and  use
	      the  matte  channel  information	to produce a monochrome image.
	      The resulting RLE image file will contain only one color channel
	      instead of the usual four (RGB + alpha).

       -o outfile
	      If  specified, the output will be written to this file.  If out‐
	      file is "-", or if it is not specified, the output will be writ‐
	      ten to the standard output stream.

       infile.rla
	      The  name	 of the Wavefront image data file to be converted.  It
	      is not necessary to supply the ".rla" or ".rlb" extension as  it
	      will be added to the supplied name if not already there.

EXAMPLES
       rlatorle -v test.0001.rla -o test.rle
	      While running in verbose mode, convert test.0001.rla to RLE for‐
	      mat and store resulting data in test.rle.

       rlatorle test.0001.rla | mcut >test.rle
	      Convert test.0001.rla to RLE format and convert to 8 bit	mapped
	      color before storing data in test.rle

       rlatorle -h test.0001.rla
	      Dump  the	 header	 information  of  the  Wavefront  file	called
	      test.0001.rla.

       rlatorle -b test.0001 | get4d
	      Convert test.0001.rlb to RLE format and  display	the  resulting
	      image.
