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.
