ppmtotga(1)


NAME

   ppmtotga - convert portable pixmap into a TrueVision Targa file

SYNOPSIS

   ppmtotga [-mono|-cmap|-rgb] [-norle] [ppmfile]

DESCRIPTION

   Reads  a portable pixmap as input.  Produces a TrueVision Targa file as
   output.

OPTIONS

   -mono  Forces Targa file to be of type 8 bit monochrome.  Input must be
          a portable bitmap or a portable graymap.

   -cmap  Forces  Targa file to be of type 24 bit colormapped.  Input must
          be a portable bitmap, a portable graymap or  a  portable  pixmap
          containing no more than 256 distinct colors.

   -rgb   Forces Targa file to be of type 24 bit unmapped color.

   -norle Disables  run-length  encoding,  in case you have a Targa reader
          which can't read run-length encoded files.

   All flags can be abbreviated to their shortest unique  prefix.   If  no
   file  type  is  specified the most highly constained compatible type is
   used, where monochrome is more constained than colormapped which is  in
   turn more constained than unmapped.

BUGS

   Does  not  support  all possible Targa file types.  Should really be in
   PNM, not PPM.
