NAME
       tgatoppm	 -  convert TrueVision Targa file into a portable
       pixmap

SYNOPSIS
       tgatoppm	 [--alphaout={alpha-filename,-}]   [--headerdump]
       tga-filename

DESCRIPTION
       Reads  a	 TrueVision  Targa  file  as  input.   Produces a
       portable pixmap as output.

OPTIONS
       --alphaout=alpha-filename
	      tgatoppm creates a PGM (portable graymap) file con
	      taining  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,  tgatoppm  does  not	generate an alpha
	      file, and if the input image has an alpha	 channel,
	      tgatoppm simply discards it.

	      If  you  specify - as the filename, tgatoppm writes
	      the alpha output to Standard  Output  and	 discards
	      the image.

	      See  pnmcomp(1) for one way to use the alpha output
	      file.

       --headerdump
	      Causes the  header  information  to  be  dumped  to
	      stderr.

       All  options  can  be abbreviated to their shortest unique
       prefix.	Should really be in PNM, not PPM.
