We acknowledge the substantial contributions to the ImageMagick project by
these gifted individuals (listed in alphabetical order):
Authored the Cineon image coder (based on the existing DPX source).
Rod Bogart and John W. Peterson, University of Utah
Image compositing is loosely based on rlecomp of the Utah Raster Toolkit.
Original author of the JP2 coder.
Created a Borland C++ Builder 6.0 build environment for ImageMagick.
Thomas R Crimmins
Inventor of the eight hull algorithm used for speckle reduction.
Authored the source RPM spec file for ImageMagick.
Authored the CUT, ART, and MATLAB coder modules.
Francis J. Franklin
Ported the WMF coder to the libwmf 0.2 API.
Original author of Base64 encode/decode sources.
Author of Magick++ (C++ API to ImageMagick). 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.
Michael Halle, Spatial Imaging Group at MIT
Contributed the initial implementation of Alan Paeth's image rotation
Contributed (with Leonard Rosenthol) dash pattern, linecap stroking
algorithm, and minor rendering improvements.
Christopher R. Hawks
Authored the PALM coder.
Paul Heckbert, Carnegie Mellon University
Image resizing is loosely based on Paul Heckbert's Zoom program.
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.
Contributed code to support filling drawn objects using a pattern image.
Contributed a ZX-Spectrum SCREEN$ reader.
David Pensak, E. I. du Pont de Nemours and Company
For providing the computing environment that made developing ImageMagick
Author of the VisualMagick project configure facility for Visual C++.
Author of FlashPix module. 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.
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.
Paul Raveling, USC Information Sciences Institute
The spatial subdivision color reduction algorithm is based on his Img
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

Lars Ruben Skyum
Contributed the -clippath functionality, improved color profile support,
and re-wrote the PS3 coder.
Alvy Ray Smith and Eric Ray Lyons
HWB color transform and algorithm.
Michael Still and IBM developer Works
For the excellant article, "Graphics from the command line". First
published by IBM DeveloperWorks.
Created and maintains a comprehensive set of examples of using ImageMagick
(especially version 6 and above), which doubles as a command line
Contributed support for Wireless BitMap, used in WAP - Wireless Access
Responsible for the ImageMagick Linux binary distributions for many years.
His efforts are very much appreciated.
