significant contribution was made and not recorded.
- 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.
- 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.
Maintains the SourceForge mailing lists.
- Jaroslav Fojtik
- Authored the ART, CUT, MAC, MATLAB, TOPOL, and WPG
coder modules.
- 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.
- Richard Nolde
- Contributed code for converting between native floating
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.
- John Cristy
- Creator, principal author, and principal maintainer of
ImageMagick, from which GraphicsMagick is originally
derived (from ImageMagick 5.5.2). Also the author of
the Wand API to ImageMagick which is incorporated as
a stand-alone library by GraphicsMagick.
- Kelly Bergougnoux
- Authored the initial Cineon coder (which has since been
replaced).
- Christopher R. Hawks
- Authored the PALM coder.
- Francis J. Franklin
- Ported the WMF coder to the libwmf 0.2 API.
- Rick Mabry
- Contributed code to support filling drawn objects using a
pattern image.
- Nathan Brown
- Original author of the JP2 coder.
- Kyle Shorter
- Original author of PerlMagick. Original author of the
LOCALE coder.
- Markus Friedl
- Original author of Base64 encode/decode sources.
- David Harr
- Contributed (with Leonard Rosenthol) dash pattern,
linecap stroking algorithm, and minor rendering
improvements.
- Troy Edwards
- Authored the source RPM spec file for GraphicsMagick.
- Milan Votava
- Contributed support for Wireless BitMap, used in WAP -
Wireless Access Protocol.
- Mike Edmonds
- Contributed the median filter algorithm.
- David Pensak, E. I. du Pont de Nemours and Company
- For providing the computing environment that made
developing ImageMagick possible.
- Alexander Zimmermann
- Responsible for the ImageMagick Linux binary
distributions for many years. His efforts are very much
appreciated.
- Paul Heckbert, Carnegie Mellon University
- Image resizing is based on Paul Heckbert's Zoom program.
- Paul Raveling, USC Information Sciences Institute
- The spatial subdivision color reduction algorithm is
based on his Img software.
- Michael Halle, Spatial Imaging Group at MIT
- For the initial implementation of Alan Paeth's image
rotation algorithm.
- 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.
- Rod Bogart and John W. Peterson, University of Utah
- Image compositing is loosely based on rlecomp of the
Utah Raster Toolkit.
- Alvy Ray Smith and Eric Ray Lyons
- HWB color transform and algorithm.
- Thomas R Crimmins
- Inventor of the eight hull algorithm used for speckle
reduction.
