1 These active developers and have made source code contributions to the
2 ImageMagick project in the last few years:
5 Principal architect of ImageMagick and still maintains the ImageMagick
9 Contributor to and maintainer of Magick++, OpenCL acceleration, and
10 the Windows build (configure, ImageMagickObject, etc.).
13 Contributed significantly to the utilities. Authored support for JNG,
14 MNG, and PNG formats. Provided significant support for the BMP format.
15 Made significant improvements to the documentation.
18 Various patches from Debian downstream.
21 Contributed support and documentation for the discrete Fourier transform,
22 connected component labeling, perceptual hash, kuwahara filter and others.
23 Also provides scripts that perform some out-of-the ordinary image
24 processing operations @ http://www.fmwconcepts.com/imagemagick/. He
25 utilized his scripts as unit tests for ImageMagick version 7 to ensure
26 version 6 compatibility before its release.
29 These individuals have made source code contributions to the ImageMagick
30 project in the past but are no longer active developers:
33 Authored the Cineon image coder (based on the existing DPX source).
36 Original author of the JP2 coder.
39 Accelerate numerous image filters with OpenCL under AMD, Intel,
40 and NVidia. Adapted from MulticoreWare OpenCL contribution.
43 Created a Borland C++ Builder 6.0 build environment for ImageMagick.
46 Authored the source RPM spec file for ImageMagick.
49 Authored the CUT, ART, and MATLAB coder modules.
52 Ported the WMF coder to the libwmf 0.2 API.
55 Original author of Base64 encode/decode sources.
58 Author of Magick++ (C++ API to ImageMagick). Author of module loader
59 facility, automatic file identification (magic) support, Unix/Cygwin/MinGW
60 configure/make facility, Windows setup.exe style installer, WMF renderer,
61 C API documentation formatter, and the C, C++, and Perl test suites
65 Contributed (with Leonard Rosenthol) dash pattern, linecap stroking
66 algorithm, and minor rendering improvements.
69 Authored the PALM coder.
72 Contributed code to support filling drawn objects using a pattern image
73 and major improvements to the web page (both content and appearance).
76 Contributed a ZX-Spectrum SCREEN$ reader.
78 Chantal Racette, Laurentian University
79 Sped up Sinc and Blackman filter kernels. EWA resampling code
83 Author of the VisualMagick project configure facility for Visual C++.
84 Author of FlashPix module. Author of the EMF, XTRN, and META coders.
85 Significant contributions to the MSL, JPEG, TIFF, SVG, and URL coders.
86 Authored "process" module support. Wrote the micro-timer facility used
87 by 'identify'. Ported module loader support to Windows. Significantly
88 improved polygon rendering performance.
90 Nicolas Robidoux, Laurentian University
91 New ellipse clamping method and vertical/horizontal line preserving
92 filters for EWA resampling. Sped up resampling filter kernels.
95 Authored the 'conjure' utility and associated MSL execution environment.
96 Provided MacOS support. Authored the CLIPBOARD, XCF, and PSD coders.
97 Postscript and PDF expertise. Significant drawing enhancements including
98 support for dash patterns, linecap stroking, clipping masks and a
102 Original author of PerlMagick. Author of the LOCALE coder.
105 Contributed the -clippath functionality, improved color profile support,
106 and re-wrote the PS3 coder.
109 Designed the ImageMagick 6.0 command line processing with parenthesis,
110 image sequence operators, and GIF animation processing. Wrote the
111 image perspective distortions (-distort) and resampling methods.
112 Maintains a comprehensive set of examples of using ImageMagick at
113 https://www.imagemagick.org/Usage/.
116 Contributed support for Wireless BitMap, used in WAP - Wireless Access
120 We acknowledge these non-developer contributors to the ImageMagick project:
123 Contributed numerous fuzzed-images that revealed program flaws in
124 ImageMagick. Additional checks were added to guard against nefarious
127 Rod Bogart and John W. Peterson, University of Utah
128 Image compositing is loosely based on rlecomp of the Utah Raster Toolkit.
131 Inventor of the eight hull algorithm used for speckle reduction.
133 Michael Halle, Spatial Imaging Group at MIT
134 Contributed the initial implementation of Alan Paeth's image rotation
137 Paul Heckbert, Carnegie Mellon University
138 Image resizing is loosely based on Paul Heckbert's Zoom program.
140 Peder Langlo, Hewlett Packard
141 Made hundreds of suggestions and bug reports. Without Peder, this
142 software would not be nearly as useful as it is today.
144 David Pensak, E. I. du Pont de Nemours and Company
145 For providing the computing environment that made developing ImageMagick
148 Paul Raveling, USC Information Sciences Institute
149 The spatial subdivision color reduction algorithm is based on his
152 Alvy Ray Smith and Eric Ray Lyons
153 HWB color transform and algorithm.
156 Responsible for the ImageMagick Linux binary distributions for many years.
157 His efforts are very much appreciated.
