Cristy is the principal architect of ImageMagick and still maintains the
ImageMagick distribution.
We acknowledge the substantial contributions to the ImageMagick project by
these gifted individuals (listed in alphabetical order):
Kelly Bergougnoux
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.
Nathan Brown
Original author of the JP2 coder.
Mike Chiarappa
Created a Borland C++ Builder 6.0 build environment for ImageMagick.
Thomas R Crimmins
Inventor of the eight hull algorithm used for speckle reduction.
Troy Edwards
Authored the source RPM spec file for ImageMagick.
Jaroslav Fojtik
Authored the CUT, ART, and MATLAB coder modules.
Francis J. Franklin
Ported the WMF coder to the libwmf 0.2 API.
Markus Friedl
Original author of Base64 encode/decode sources.
Bob Friesenhahn
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
algorithm.
David Harr
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.
As is the basic EWA resampling used for image distortions.
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.
Rick Mabry
Contributed code to support filling drawn objects using a pattern image
and major improvements to the web page (both content and appearance).
Catalin Mihaila
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
possible.
Chantal Racette, Laurentian University
Sped up Sinc and Blackman filter kernels. EWA resampling code
verification.
William Radcliffe
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.
Glenn Randers-Pehrson
Contributed significantly to the utilities. 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
software.
Nicolas Robidoux, Laurentian University
New ellipse clamping method and vertical/horizontal line preserving
filters for EWA resampling. Sped up of resampling filter kernels.
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.
Kyle Shorter
Original author of PerlMagick. Author of the LOCALE coder.
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.
Anthony Thyssen
Designed the ImageMagick 6 command line processing with parenthesis,
image sequence operators, and GIF animation processing. Checking and
update of the Composition Methods. Wrote the image distortions
(-distort) and EWA resampling methods. Redesign and formalization of
Resize Filters. Addition of the morphology operators, built in kernels
for morphology and convolution processing. Redesign of ImageMagick
7 command line, to allow scripting and pipelining of options.
Maintains a comprehensive set of examples of using ImageMagick at
http://www.imagemagick.org/Usage/.
Milan Votava
Contributed support for Wireless BitMap, used in WAP - Wireless Access
Protocol.
Fred Weinhaus
Contributed support and documentation for the discrete Fourier transform.
Comments and testing of Convolution and Distortion Operations.
Also provides scripts that perform some out-of-the ordinary image
processing operations at http://www.fmwconcepts.com/imagemagick/.
Alexander Zimmermann
Responsible for the ImageMagick Linux binary distributions for many years.
His efforts are very much appreciated.
