NAME
       tgatoppm - convert TrueVision Targa file to a PPM image


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


DESCRIPTION
       This program is part of Netpbm(1)

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


OPTIONS
       All options can be abbreviated to their shortest unique prefix.




       --alphaout=alpha-filename
              tgatoppm  creates a PGM image containing 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 pamcomp(1)
               for one way to use the alpha output file.


       --headerdump
              Causes tgatoppm to dump information from the TGA header to
              Standard Error.
