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.
