-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.
+
+Dirk Lemstra
+ Contributor to and maintainer of Magick++, OpenCL acceleration, and
+ the Windows build (configure, ImageMagickObject, etc.).
+
+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.
+
+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+project in the past but are no longer active developers:
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.
+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.
-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.
