tgatoppm(1)

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.

BUGS

   Should really be in PNM, not PPM.
