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.
