NAME

       targatorle - Convert Truevision TARGA images to RLE format.


SYNOPSIS

       targatorle [ -h headerfile ] [ -n nchannels ] [ -o outfile.rle ] [
       infile.tga ]


DESCRIPTION

       Targatorle converts a file from Truevision's TARGA format into RLE
       format.  If no input file is specified, the data is read from stdin.
       Targatorle recognizes (but cannot necessarily process) all of the image
       subtypes defined by the 1989 TARGA 2.0 specification:

             0- Header Only, No Image Data
             1- Uncompressed, Color-mapped Image
             2- Uncompressed, True-color Image
             3- Uncompressed, B/W (gray scale) Image
             9- Run-length encoded, Color-mapped Image
             10- Run-length encoded, True-color Image
             11- Run-length encoded, B/W Image

       Targatorle should correctly process images in formats 0, 2, 3, 10, and
       11.  No support is currently available for color mapped images.


OPTIONS

       -h     Allow the program to write TARGA header information to
              headerfile

       -n     where nchannels is 3 or 4.  If input is a color image, copy only
              nchannels of the TARGA file; this allows the alpha channel to be
              stripped.  By default, the alpha channel will be copied if
              present.

       -o     Use outfile as output instead of stdout.


LIMITATIONS

       The TARGA image descriptor byte is ignored; therefore, the image origin
       is assumed to be that of RLE(5) (bottom left).  None of the color-
       mapped TARGA formats (types 1 and 9) are supported.  Finally, no
       attempt has been made to support extensions to the TARGA File Format
       introduced by Truevision in 1989 (new support for time stamps,
       comments, user-defined data fields, etc.).
