-We acknowledge the substantial contributions to the ImageMagick project by
-these gifted individuals (listed in alphabetical order):
+Cristy
+ Principal architect of ImageMagick and still maintains the ImageMagick
+ distribution.
+
+Siu Chi Chan
+ Accelerate numerous image filters with OpenCL under AMD, Intel,
+ and NVidia. Adapted from MulticoreWare OpenCL contribution.
+
+Dirk Lemstra
+ Contributed to Magick++ and the Windows distribution.
+
+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.
+
+Nicolas Robidoux, Laurentian University
+ New ellipse clamping method and vertical/horizontal line preserving
+ filters for EWA resampling. Sped up resampling filter kernels.
+
+Bastien ROUCARIÈS
+ Various patches from Debian downstream.
+
+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
+ http://www.imagemagick.org/Usage/.
+
+Fred Weinhaus
+ Contributed support and documentation for the discrete Fourier transform.
+ Also provides scripts that perform some out-of-the ordinary image
+ processing operations @ http://www.fmwconcepts.com/imagemagick/.
+

+
+These individuals have made source code contributions to the ImageMagick
+project in the past but are no longer active developers:
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.
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
and major improvements to the web page (both content and appearance).
Catalin Mihaila
Contributed a ZX-Spectrum SCREEN$ reader.

- 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.
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
+ 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,

- 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 (Robidoux, LanczosSharp and Lanczos2Sharp),
- for EWA resampling. Faster filter kernels (minimax Sinc
- approximation, and simplified Blackman and Bohman).
-
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
