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 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 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.
