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 Accelerate numerous image filters with OpenCL under AMD, Intel,
10 and NVidia. Adapted from MulticoreWare OpenCL contribution.
13 Contributed to Magick++ and the Windows distribution.
16 Contributed significantly to the utilities. Authored support for JNG,
17 MNG, and PNG formats. Provided significant support for the BMP format.
18 Significant improvements to the documentation.
20 Nicolas Robidoux, Laurentian University
21 New ellipse clamping method and vertical/horizontal line preserving
22 filters for EWA resampling. Sped up resampling filter kernels.
25 Various patches from Debian downstream.
28 Designed the ImageMagick 6.0 command line processing with parenthesis,
29 image sequence operators, and GIF animation processing. Wrote the
30 image perspective distortions (-distort) and resampling methods.
31 Maintains a comprehensive set of examples of using ImageMagick at
32 http://www.imagemagick.org/Usage/.
35 Contributed support and documentation for the discrete Fourier transform.
36 Also provides scripts that perform some out-of-the ordinary image
37 processing operations @ http://www.fmwconcepts.com/imagemagick/.
41 These individuals have made source code contributions to the ImageMagick
42 project in the past but are no longer active developers:
45 Authored the Cineon image coder (based on the existing DPX source).
48 Original author of the JP2 coder.
51 Created a Borland C++ Builder 6.0 build environment for ImageMagick.
54 Authored the source RPM spec file for ImageMagick.
57 Authored the CUT, ART, and MATLAB coder modules.
60 Ported the WMF coder to the libwmf 0.2 API.
63 Original author of Base64 encode/decode sources.
66 Author of Magick++ (C++ API to ImageMagick). Author of module loader
67 facility, automatic file identification (magic) support, Unix/Cygwin/MinGW
68 configure/make facility, Windows setup.exe style installer, WMF renderer,
69 C API documentation formatter, and the C, C++, and Perl test suites
73 Contributed (with Leonard Rosenthol) dash pattern, linecap stroking
74 algorithm, and minor rendering improvements.
77 Authored the PALM coder.
80 Contributed code to support filling drawn objects using a pattern image
81 and major improvements to the web page (both content and appearance).
84 Contributed a ZX-Spectrum SCREEN$ reader.
86 Chantal Racette, Laurentian University
87 Sped up Sinc and Blackman filter kernels. EWA resampling code
91 Author of the VisualMagick project configure facility for Visual C++.
92 Author of FlashPix module. Author of the EMF, XTRN, and META coders.
93 Significant contributions to the MSL, JPEG, TIFF, SVG, and URL coders.
94 Authored "process" module support. Wrote the micro-timer facility used
95 by 'identify'. Ported module loader support to Windows. Significantly
96 improved polygon rendering performance.
99 Authored the 'conjure' utility and associated MSL execution environment.
100 Provided MacOS support. Authored the CLIPBOARD, XCF, and PSD coders.
101 Postscript and PDF expertise. Significant drawing enhancements including
102 support for dash patterns, linecap stroking, clipping masks and a
106 Original author of PerlMagick. Author of the LOCALE coder.
109 Contributed the -clippath functionality, improved color profile support,
110 and re-wrote the PS3 coder.
113 Contributed support for Wireless BitMap, used in WAP - Wireless Access
117 We acknowledge these non-developer contributors to the ImageMagick project:
119 Rod Bogart and John W. Peterson, University of Utah
120 Image compositing is loosely based on rlecomp of the Utah Raster Toolkit.
123 Inventor of the eight hull algorithm used for speckle reduction.
125 Michael Halle, Spatial Imaging Group at MIT
126 Contributed the initial implementation of Alan Paeth's image rotation
129 Paul Heckbert, Carnegie Mellon University
130 Image resizing is loosely based on Paul Heckbert's Zoom program.
132 Peder Langlo, Hewlett Packard
133 Made hundreds of suggestions and bug reports. Without Peder, this
134 software would not be nearly as useful as it is today.
136 David Pensak, E. I. du Pont de Nemours and Company
137 For providing the computing environment that made developing ImageMagick
140 Paul Raveling, USC Information Sciences Institute
141 The spatial subdivision color reduction algorithm is based on his
144 Alvy Ray Smith and Eric Ray Lyons
145 HWB color transform and algorithm.
148 Responsible for the ImageMagick Linux binary distributions for many years.
149 His efforts are very much appreciated.
