These active developers have made source code contributions to the ImageMagick project in the last few years: Cristy Principal architect of ImageMagick and still maintains the ImageMagick distribution. Dirk Lemstra Contributor to and maintainer of Magick++, OpenCL acceleration, and the Windows build. Bastien ROUCARIÈS Various patches from Debian downstream. Fred Weinhaus Contributed support and documentation for the discrete Fourier transform, connected component labeling, perceptual hash, kuwahara filter and others. Also provides scripts that perform some out-of-the ordinary image processing operations @ http://www.fmwconcepts.com/imagemagick/. He utilized his scripts as unit tests for ImageMagick version 7 to ensure version 6 compatibility before its release. These individuals have made source code contributions to the ImageMagick project in the past but are no longer active developers: Glenn Randers-Pehrson Contributed significantly to the utilities. Authored support for JNG, MNG, and PNG formats. Provided significant support for the BMP format. Made significant improvements to the documentation. Kelly Bergougnoux Authored the Cineon image coder (based on the existing DPX source). Nathan Brown Original author of the JP2 coder. Siu Chi Chan Accelerate numerous image filters with OpenCL under AMD, Intel, and NVidia. Adapted from MulticoreWare OpenCL contribution. Mike Chiarappa Created a Borland C++ Builder 6.0 build environment for ImageMagick. 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. David Harr Contributed (with Leonard Rosenthol) dash pattern, linecap stroking algorithm, and minor rendering improvements. Christopher R. Hawks Authored the PALM coder. 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. 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, 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. Nicolas Robidoux, Laurentian University New ellipse clamping method and vertical/horizontal line preserving filters for EWA resampling. Sped up 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. Anthony Thyssen Designed the ImageMagick 6.0 command line processing with parenthesis, image sequence operators, and GIF animation processing. Wrote the image perspective distortions (-distort) and resampling methods. Maintains a comprehensive set of examples of using ImageMagick at https://legacy.imagemagick.org/Usage/. Milan Votava Contributed support for Wireless BitMap, used in WAP - Wireless Access Protocol. We acknowledge these non-developer contributors to the ImageMagick project: Hanno Böck Contributed numerous fuzzed-images that revealed program flaws in ImageMagick. Additional checks were added to guard against nefarious image files. Rod Bogart and John W. Peterson, University of Utah Image compositing is loosely based on rlecomp of the Utah Raster Toolkit. Thomas R Crimmins Inventor of the eight hull algorithm used for speckle reduction. Michael Halle, Spatial Imaging Group at MIT Contributed the initial implementation of Alan Paeth's image rotation algorithm. 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. David Pensak, E. I. du Pont de Nemours and Company For providing the computing environment that made developing ImageMagick possible. Paul Raveling, USC Information Sciences Institute The spatial subdivision color reduction algorithm is based on his Img software. Alvy Ray Smith and Eric Ray Lyons HWB color transform and algorithm. Alexander Zimmermann Responsible for the ImageMagick Linux binary distributions for many years. His efforts are very much appreciated.
