Author of module loader facility, automatic file
identification (magic) support, Unix/Cygwin/MinGW
configure/make facility, Windows setup.exe style
installer, WMF renderer, C API documentation formatter,
and the C, C++, and Perl test suites used by ImageMagick

Visual C++. Author of FlashPix module. Author of the
ImageMagickObject COM object for Windows. Author of the
EMF, XTRN, and META coders. Significant contributions to
the MSL, JPEG, TIFF, SVG, and URL coders. Authored
"process" module support. Wrote the micro-timer facility
used by 'identify'. Ported module loader support to
Windows. Significantly improved polygon rendering
performance.
Glenn Randers-Pehrson
Contributed significantly to the utilities, including
writing the 'gm' utility wrapper. Authored support for
JNG, MNG, and PNG formats. Provided significant support
for the BMP format. Significant improvements to the
documentation, including creating a documentation
authoring environment based on the <imdoc> format.
Leonard Rosenthol
Authored the 'conjure' utility and associated MSL
execution environment. Provided MacOS support. Authored
the CLIPBOARD, XCF, and PSD coders. Postscript and PDF
expertise. Significant drawing enhancements including
support for dash patterns, linecap stroking, clipping
masks and a mask image.
Lars Ruben Skyum
Contributed the -clippath functionality, added
-define support, improved color profile support,
and re-wrote the PS3 coder.
John Cristy
Creator, principal author, and principal maintainer of
ImageMagick, from which GraphicsMagick is originally
derived (from ImageMagick 5.5.2). Also the author of
the Wand API to ImageMagick which is incorporated as
a stand-alone library by GraphicsMagick.
Jaroslav Fojtik
Authored the ART, CUT, MATLAB, TOPOL, and WPG
coder modules.
Kelly Bergougnoux
Authored the Cineon coder.
Christopher R. Hawks
Authored the PALM coder.
Francis J. Franklin
Ported the WMF coder to the libwmf 0.2 API.
Rick Mabry
Contributed code to support filling drawn objects using a
pattern image.
Nathan Brown
Original author of the JP2 coder.
Kyle Shorter
Original author of PerlMagick. Original author of the
LOCALE coder.
Markus Friedl
Original author of Base64 encode/decode sources.
David Harr
Contributed (with Leonard Rosenthol) dash pattern,
linecap stroking algorithm, and minor rendering
improvements.
Troy Edwards
Authored the source RPM spec file for GraphicsMagick.
Milan Votava
Contributed support for Wireless BitMap, used in WAP -
Wireless Access Protocol.
David Pensak, E. I. du Pont de Nemours and Company
For providing the computing environment that made
developing ImageMagick possible.
Alexander Zimmermann
Responsible for the ImageMagick Linux binary
distributions for many years. His efforts are very much
appreciated.
Paul Heckbert, Carnegie Mellon University
Image resizing is based on Paul Heckbert's Zoom program.
Paul Raveling, USC Information Sciences Institute
The spatial subdivision color reduction algorithm is
based on his Img software.
Michael Halle, Spatial Imaging Group at MIT
For the initial implementation of Alan Paeth's image
rotation algorithm.
Peder Langlo, Hewlett Packard
Made hundreds of suggestions and bug reports. Without
Peder, this software would not be nearly as useful as it
is today.
Rod Bogart and John W. Peterson, University of Utah
Image compositing is loosely based on rlecomp of the
Utah Raster Toolkit.
Alvy Ray Smith and Eric Ray Lyons
HWB color transform and algorithm.
Thomas R Crimmins
Inventor of the eight hull algorithm used for speckle
reduction.
