Here is a more or less complete list of people who contributed to
the Xloadimage from which Pamx was derived. The list is from the README
file in the Xloadimage source code:
Special thanks to the crew at the Boston University Graphics Lab for
their assistance and sample images, and to bzs@std.com for his simple
dithering algorithm (or what's left of it). Real special thanks to
Kirk L. Johnson (tuna@athena.mit.edu) for a very nice GIF loader and
dithering routine, to Mark Snitily (zok!mark@apple.com) for 386/ix
compatibility work, to Andreas Stolcke (stolcke@icsib12.berkeley.edu)
for miscellaneous bug fixes, to Anthony A. Datri (datri@convex.com)
for a number of things, to Mark Moraes (moraes@cs.toronto.edu) for
the slideshow colormap fix, to Gregg Townsend (gmt@cs.arizona.edu) for
a suggested dithering routine and other fixes, to Brian Frost
(B1F5814@RIGEL.TAMU.EDU) for changes for VMS, to Chip Horstman for G3
FAX support, to Deron Dann Johnson (dj@eng.sun.com) for fixing the
RetainTemporary bug, to Tom Tatlow (tatlow@dash.enet.dec.com) for
image rotation code, to Mark A. Horstman (mhorstm@sarek.sbc.com) for
tilde expansion in .xloadimagerc files and virtual-root support in
root.c, to Tim Roper (timr@labtam.labtam.oz.au), Graeme Gill
(graeme@labtam.oz.au) for gamma correction and Utah RLE image support,
Mark Majhor (uunet!sequent!markm) for FBM and MacPaint support, Ian
MacPhedran (macphed@dvinci.usask.ca) for PGM and PPM support, Per
Fogelstrom (pf@diab.se) for a fix to send.c, Hans J. Albertsson
(hans@Sweden.Sun.COM) for cleaning up GIF aborting, Graham Hudspith
(gwh@inmos.com) for a geometry patch, Glenn P. Davis
(davis@unidata.ucar.edu) for McIDAS areafile support, Keith S. Pickens
(maxwell.nde.swri.edu!ksp) for fixing the RLE loader to work with the
updated zio package, Mike Douglas (douglas@wilbur.coyote.trw.com) for
normalization, Rod Johnson (johnson@wrl.epi.com) for speedup
suggestions, Hal Peterson (hrp@cray.com) for his Imakefile fix, Matt
Caprile (Matthew.Caprile@ec.bull.fr) for slideshow delay code, Bob
Deroy (rwd@bucrsb.bu.edu) for mondo 24-bit Sun Rasterfile images that
broke everything, Christos S. Zoulas (christo@ee.cornell.edu) for a
first-cut 24-bit implementation, Gerald James Barnes
(gjb@oasis.icl.stc.co.uk) for a first-cut forced-visual
implementation, Michael Campanella (campanella@cvg.enet.dec.com) for
more VMS changes, Kee Hinckley (nazgul@alfalfa.com) for robustness
changes to the g3 and MacPaint loaders and the ZIO package, Tim
Northrup (tim@brspyr1.brs.com) for PC Paintbrush and GEM image
formats, Richard Weidner (richard@elroy.jpl.nasa.gov) for lots of
24-bit testing, Eckhard Rueggeberg (erueg@cfgauss.uni-math.gwdg.de)
for a better PCX loader, and any others whose names I've missed.
