Active GraphicsMagick Contributors
==================================
Bob Friesenhahn
Principal maintainer of GraphicsMagick. Author of
Magick++ (C++ API to ImageMagick and GraphicsMagick).
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
and GraphicsMagick.
Jaroslav Fojtik
Authored the ART, CUT, HRZ, JNX, MAC, MATLAB, TOPOL,
and WPG coder modules. Improved the FITS and TXT coder
modules. VisualMagick 'configure' improvements and
build testing/fixes for many versions of Microsoft
Visual Studio.

Glenn Randers-Pehrson
Contributed significantly to the utilities, including
writing the 'gm' utility wrapper. Authored support for
JNG, MNG, and PNG formats. Provided significant
support for the BMP format. Significant improvements
to the documentation, including creating a
documentation authoring environment based on the
<imdoc> format. Maintained the SourceForge mailing
lists. GraphicsMagick would not be what it is today
without Glenn and he will always be remembered.
Gregory J Wolfe
Contributed significant improvements to the SVG
parsing and rendering code.
Troy Patteson
Contributed a several significant patches to fix image
rotation bugs and improve image rotation performance,
as well as an improved bi-linear interpolation
implementation.
Kenneth Xu
Contributed the implementation of 'gm batch', a simple
batch mode for GraphicsMagick.
Sara Shafaei
Contributed a number of Wand API functions as well as
fixes for several composition operators.
Brendan Lane
Contributed a large number of new Photoshop
composition operators and alpha-channel fixes for
existing ones.
Dirk Lemstra
Contributed improvements to the VisualMagick configure
program to support configuring more build options via
the GUI dialogs and to deal with similarly named
files.
Roman Hiestand
Contributed WebP coder improvements.
Mike Chiarappa
Created and maintains the Borland C++ Builder 6.0 build
environment for GraphicsMagick.
Daniel Kobras
Provided many security patches and fixes from the Debian
project.
William Radcliffe
Author of the VisualMagick project configure facility for
Visual C++. Author of FlashPix module. Author of the
ImageMagickObject COM object for Windows. 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 improved polygon rendering
performance.
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.
Lars Ruben Skyum
Contributed the -clippath functionality, added
-define support, improved color profile support,
and re-wrote the PS3 coder.
Rolf Schroedter
Principal author of TclMagick.
David N. Welton
Co-author of TclMagick, particularly in the Unix environment.
Mark Mitchell
Contributed a new design for the web pages, including the
formatting scripts, and converted many pages to the new
format.

point types, and short (16/24) bit float types.
Clément Follet
Contributed Hald CLUT and ASC-CDL implementations.
John Sergeant
Re-wrote the HP PCL writer to work much better,
including support for compression. Implemented
support for CALS type 1 format. Re-wrote the DICOM
reader.
Roberto de Deus Barbosa Murta
Contributed the adaptive threshold implementation
(-lat), which executes in linear rather than quadratic
time.
Samuel Thibault
Contributed support for the Braille image format.
