[David M. Laur]

In an effort to help out those people struggling with image format
conversions on their SGI IRIS/4D workstations, I've made some of
of my more useful image utility programs available as executables.

In particular, these utilities read images in the following formats:

   TIFF GIF Sun(ras) Alias(als) Targa(tga) SGI(rgb) Xwd PNM(pbm) HDF sim

There are programs for converting these to Encapsulated PostScript(tm)
image descriptions (color or grayscale), TIFF, or SGI (Haeberli) formats.
There's also a display program for the IRIS, which can also show
short movie loops or 'slide-shows'.

The compressed tar-format archive is
available via anonymous ftp on gauguin.princeton.edu (128.112.128.70)
in the file pub/pxtools.tar.Z

get this file in binary mode, then extract the
README file, and the bin and man subdirectories:

  zcat pxtools.tar.Z | tar xvof -

Here's a brief overview of the provided tools:

 NAME
      pxtools - various Princeton ICGL written image utilities

 SYNOPSIS
      pxcat [ -vtfhpwWmrRHS ] imgfile [additional files to concatenate]

      pxdraw [ -vtfgmcBTpbCVFSOx? ] [ files ... ]

      px2sgi [ -vg ] [ infile ] new_sgi_file

      px2ps [ -vgrfsbpo4NGCPK# ] [ imgfile ]

 DESCRIPTION
      pxfmts (4L)   - image types read by the 'px' tools:
                       TIFF GIF Sun(ras) Alias(als) Targa(tga) SGI(rgb)
                       Xwd PNM(pbm) HDF GWH sim ICGLpix
      pxcat (1L)    - read image file(s), convert to 'ICGLpix' format
      pxdraw (1L)   - draw image file(s) on an SGI/IRIS-4D display screen
      px2ps (1L)    - convert ICGLpix image data to PostScript
      px2sgi (1L)   - convert ICGLpix image data to SGI (rle,rgb,bw) format
      px2tiff (1L)  - convert ICGLpix image data to TIFF format
