- IFF2PS 2.0
- ----------
-
- This is the latest version of iff2ps. Iff2ps takes an IFF ILBM file
- as input and produces a PostScript file that may be sent to a
- PostScript printer (e.g., an Apple LaserWriter) for printing. The
- image portion in the PostScript file is compressed. Decompression is
- done by the PostScript interpreter within the printer. If no files
- are given on the command line, the standard input is read, and the
- standard output is written to. If only one file is given on the
- command line, then that file must be an IFF file, and the standard
- output is written to. Note that you cannot specify a PostScript
- output file and have standard input read. The output file conforms to
- the Adobe 2.0 file structuring conventions. Command line flags may
- appear before or after the file names. All command switches are
- documented in the accompanying manual pages. Besides the troff
- source, we have enclosed also the nroff output, and the PostScript
- output of troff for people who want a nice listing of it.
-
- This is a complete rewrite from the earlier versions. For a little
- history, earlier versions were written in FORTRAN, and because of
- language limitations it had quite a few restrictions. The current
- version has been completely rewritten in C. The resulting executable
- is approximately half the size, it runs about twice as fast, and
- because of PostScript compression, it generally produces PostScript
- files that are much smaller. Furthermore, it has quite a few
- additional capabilities that can be specified with the command line
- arguments. It now handles any ILBM format: the image in the IFF
- file can be any size, can have any number of bitplanes, and all CAMG
- view modes are supported (i.e., low resolution, high resolution,
- interlace, HAM, double playfield, and HALFBRITE). However, it is
- noted that currently double playfield files are not printed quite
- correctly since both fields are printed on top of each other.
-
- As a side note, the largest IFF file that we tested it on was
- 2400x1600 pixels having 5 bitplanes. The resulting PostScript file
- was approximately 5 megabytes, and it took 2.5 hours to process it on
- an Apple LaserWriter. Can anybody top that?
-
- Finally, we note that iff2ps is copyrighted by William Mason and
- Samuel Paolucci. We do not intend the copyright to be a hindrance on
- its distribution. Basically the program can be freely redistributed
- provided the documentation accompanies the program, and is not
- included with any commercial software without the authors' written
- consent. Furthermore, the program is distributed WITHOUT ANY
- WARRANTY.
-
- Also included in the directory are two useful files. If you are lucky
- enough to have a PostScript laser printer tied directly to your Amiga,
- you should download ehandler.ps into the printer once and only once,
- preferably from within your startup-sequence. In the case you should
- send a file to the printer which contains an error, this file, which
- is an official Adobe error handler, will generate an error
- description. The second file, psclear, should be downloaded into the
- laser printer when the printer seems to just be waiting for more
- information AND you have not used ehandler.ps. This file will send an
- end-of-file to the laser printer.
