ras2tiff

ras2tiff(1)							   User Commands						       ras2tiff(1)

NAME

       ras2tiff - create a TIFF file from a Sun rasterfile

SYNOPSIS

       ras2tiff [options] input.ras output.tif

DESCRIPTION

       ras2tiff  converts  a file in the Sun rasterfile format to TIFF. By default, the TIFF image is created with data samples packed (PlanarCon-
       figuration=1), compressed with the Lempel-Ziv and Welch algorithm (Compression=5), and with each strip no  more	than  8  kilobytes.  These
       characteristics can be overridden or explicitly specified with the options described below.

       Any  colormap information in the rasterfile is carried over to the TIFF file by including a Colormap tag in the output file. If the raster-
       file has a colormap, the PhotometricInterpretation tag is set to 3 (palette). Otherwise, the PhotometricInterpretation  tag  is	set  to  2
       (RGB) if the depth is 24, or to 1 (min-is-black) if the depth is not 24.

OPTIONS

       The following options are supported:

       -c	       Specify a compression scheme to use when writing image data:

		       -c jpeg		       Baseline JPEG compression algorithm.

		       -c lzw		       Lempel-Ziv and Welch algorithm. This is the default algorithm.

		       -c none		       No compression.

		       -c packbits	       PackBits compression algorithm.

		       -c zip		       Deflate compression algorithm.

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

OPERANDS

       The following operands are supported:

       input.ras       The name of the input file that contains Sun rasterfile data.

       output.tif      The name of the output file that contains TIFF data.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWTiff			   |
       +-----------------------------+-----------------------------+
       |Interface stability	     |Uncommitted		   |
       +-----------------------------+-----------------------------+

SEE ALSO

       pal2rgb(1), tiffinfo(1), tiffcp(1), tiffmedian(1), libtiff(3)

NOTES

       Does not support all possible rasterfiles. In particular, ras2tiff does not support run-length encoded images.
