SGI2TIFF(1)              USER COMMANDS                SGI2TIFF(1)

NAME

     sgi2tiff - create a TIFF file from an SGI image file

SYNOPSIS

     sgi2tiff [ options ] input.rgb output.tif

DESCRIPTION

     sgi2tiff converts a file in the SGI image format to TIFF. By
     default,  the TIFF image is created with data samples packed
     (PlanarConfiguration=1), compressed with  the  Lempel-Ziv  &
     Welch algorithm (Compression=5), and with each strip no more
     than 8 kilobytes.  These characteristics can  overriden,  or
     explicitly specified with the options described below.

OPTIONS

     -c   Specify a compression scheme to use when writing  image
          data:   -c none for no compression, -c packbits for the
          PackBits compression algorithm), -c jpeg for the  base-
          line JPEG compression algorithm, -c zip for the Deflate
          compression algorithm, and  -c  lzw  for  Lempel-Ziv  &
          Welch (the default).

     -p   Explicitly select  the  planar  configuration  used  in
          organizing data samples in the output image:  -p contig
          for samples packed contiguously, and  -p  separate  for
          samples  stored  separately.   By  default  samples are
          packed.

     -r   Write data with a specified number of rows  per  strip;
          by default the number of rows/strip is selected so that
          each strip is approximately 8 kilobytes.

BUGS

     Does not record colormap information.
