### ImageMagick 6.0.0: Authors

John Cristy originally conceived of, authored, 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.

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.

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.

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, 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
         software.

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

         Created and maintains a comprehensive set of examples of using ImageMagick
         (especially version 6 and above), which doubles as a command line
         validation suite.

Milan Votava

         Contributed support for Wireless BitMap, used in WAP - Wireless Access
         Protocol.

Alexander Zimmermann

         Responsible for the ImageMagick Linux binary distributions for many years.
         His efforts are very much appreciated.
