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 prefix.



DESCRIPTION

       This program is part of Netpbm(1).

       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 channel  val-
              ues  in  the input image.  If the input image doesn’t contain an
              alpha channel, the alpha-filename file contains all zero (trans-
              parent) 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 out-
              put to Standard Output and discards the image.

              See pamcomp(1)foronewaytouse the alpha output file.


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