NAME

   tgatoppm - convert TrueVision Targa file to a PPM image

SYNOPSIS

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

   All options can be abbreviated to their shortest  unique  pre-
fix.

DESCRIPTION

   This program is part of Netpbm.

   tgatoppm reads a TrueVision Targa file as input and produces a
PPM image as
   output.

OPTIONS

   --alphaout=alpha-filename
	  tgatoppm creates a PGM image containing the alpha chan-
nel 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 gen-
erate 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 pamcomp for one way to use the alpha output file.
   --headerdump
	  Causes tgatoppm to dump information from the TGA header
to Standard
	  Error.
