NAME
     rgb2ps - Convert an SGI image to PostScript

SYNOPSIS
     rgb2ps inimage [-rgb]
                  [-nozoom ]
                  [-f | -flip ]
                  [-r | -rotate Angle ]
                  [-p | -ppi PixelPerInch ]
                  [-d PrinterResolution ]
                  [-z ZoomFactor ]
                  [-b bitsperpixel]

DESCRIPTION
     rgb2ps converts an SGI image file into Postscript.  This program
     generates black/white or color PostScript.  It creates the ASCII
     PostScript data.

     rgb2ps is provided for compatibility with previous Impressario releases.
     All new development should be done with the sgi2ps program.

     The rgb2ps program scales the image to fit the page and chooses the page
     orientation landscape or portrait to best match the paper.

     If the -rgb option is specified, then rgb color PostScript will be
     generated.

     If the -nozoom option is specified, then the image will be printed at its
     original size.

     If the -flip option is specified, then the image will be mirrored. This
     option can be very useful for printing on transparent material.

     If the -rotate Angle option is specified, then the image will be rotated
     at the specified Angle.

     If the -z ZoomFactor option is specified, then the image will be resized
     based on ZoomFactor. The ZoomFactor accepts float value ranging between
     0.0 to 1.0. The value 0.0 means do not zoom the image (same as nozoom
     option), 1.0 means zoom the image to fit on one page, and 0.5 means zoom
     the image to fit within half of one page. The image is always centered on
     the page. If -ppi option is specified then -z option is ignored.

     The -b option specifies how many bits to use when describing images.  The
     valid options are 1, 2, 4, and 8.  The default is 8 bits per pixel giving
     256 shades in a black and white image.

     The -ppi option specifis how many pixels per inch on both x and y axis.
     If this option is specified then the -z option will be ignored.
     The -d option specifies the printer resolution (dots per inch). The
     default resolution is 300.

WARNING
     This program has been superseded by the program sgi2ps. All new
     development should be done with sgi2ps. The rgb2ps program is provided
     for compatibility with previous releases of the Impressario product and
     may be removed from future releases.

KNOWN BUGS
     1.   Non orthogonal rotations may cause image clipping.

     2.   Explicitly specifying zero degree rotation will cause a best-fit
          image orientation.

     3.   Zooming based on ppi may not work as expected.
