Image conversions

[Doug White]

	Thanks to all who to replied to my question about 
Sun raster/ GIF/TIFF/PCX image conversions ... I got quite a bit
of info, which I've tried to encapsulate here.
For the record, I've gotten ahold of the "Fuzzy Pixmap" package,
but I need a little more time before I start spouting opinions.

	Thanks again, DWhite

I believe that there are a few good graphics format conversion programs
available via anonymous FTP from wuarchive.wustl.edu.
If you don't find what you want there, you can search the list of
known anonymous FTP sites (available from njin.pilot.edu) for strings
like "graphics", "convert", etc.

There are several packages can solve you problem.
Fuzzy Pixmap Manipulation (FBM) from uunet.uu.net /pub/fbm.tar.Z
	File Formats
        FBM   (-F)      FBM file with 256 byte header (with title & credits)
        Sun   (-S)      Sun rasterfile with 32 byte header
        Tiff  (-T)      Aldus TIFF
        PBM   (-P)      Poskanzer format for 1bit files
        GIF   (-G)      CompuServe GIF format
        RLE   (-R)      Utah RLE format
        IFF   (-I)      Amiga IFF files (except HAM mode files)
        PCX   (-Z)      PC PaintBrush format for IBM
        Face  (-B)      Bennet Yee's 1bit files, used at CMU

TIFF Library from UCBVAX.BERKELEY.EDU, file pub/tiff/v2.2.tar.Z.
Utah Raster Toolkit from CS.UTAH.EDU, file pub/toolkit-2.0.tar.Z
Jef Poskanzer's PBMPLUS source from EXPO.LCS.MIT.EDU, file contrib/pbmplus.tar.Z
There is a file in pub/image/tiff_5.0_format on alw.nih.gov about 
TIFF file format.

   You might give this package (for MS-DOS machines) a try.
GRAFWK48.ZIP  B  261744  901211  View/cvt/print MAC/IMG/GIF/TIFF/EPS graphics
  It is available on Simtel20 in the PD1:<MSDOS.GRAPHICS> directory.

Get a hold of the PBMPlus package (Portable BitMap) - available from several
archive servers (check for the comp.sources.misc archives). It has programs to
convert between all the formats you specify.
Hope this list is of some use - I've been using the pbm stuff for over a year
now for converting .gif and .tiff files into rasters, X and icon format images
and into postscript images. I highly recommend this package!
(Saying that, I've heard that the Fuzzy BitMap - FBM - package is also well
worth investing some disk space in, although we don't have the room at the
moment).

As 27 other people have probably already told you, PBMPLUS has most,
if not all, of what you seek.  expo.lcs.mit.edu:/pub has the source.

Two things I can recommend looking into:
1) Jeff Poskanzer's "Fuzzy Bit Map" (fbm) package, under *NIX.  pbm is
   good for format conversions as well, and works with fbm.
2) "Optiks", under DOS.  It can supposedly convert *many* formats, but
   it's unfortunately shareware.  You could find it at 914-353-2538.
	There are crippled versions in the archives.

There is a commercial package that runs under DOS called Hijaak that
will handle most of the conversions that you require (GIF & PCX). I'
not sure if it can handle TIF and I know it cannot handle SUN raster.
You should also try the PBM and FBM packages. These run on most UNIX
systems and also AmigaDOS. They can be gotten via anonymous ftp from
simtel20.army.mil      pd2:<unix-c.graphics> directory
They are files fbm.tar-Z and pbm.tar-Z and they contain the source code
files and appropriate make files that can be edited for your particular
unix implementation (SUN is supported and I have both up and running
on both a 386i and a Spark I). They are in compressed format so you'll
have to download that utility to uncompress it if you don't have it
already.
