Hawks 69 Authored the PALM coder. 70 71 Rick Mabry 72 Contributed code to support filling drawn objects using a pattern image 73 and major improvements to the web page (both content and appearance). 74 75 Catalin Mihaila 76 Contributed a ZX-Spectrum SCREEN$ reader. 77 78 Chantal Racette, Laurentian University 79 Sped up Sinc and Blackman filter kernels. EWA resampling code 80 verification. 81 82 William Radcliffe 83 Author of the VisualMagick project configure facility for Visual C++. 84 Author of FlashPix module. Author of the EMF, XTRN, and META coders. 85 Significant contributions to the MSL, JPEG, TIFF, SVG, and URL coders. 86 Authored "process" module support. Wrote the micro-timer facility used 87 by 'identify'. Ported module loader support to Windows. Significantly 88 improved polygon rendering performance. 89 90 Nicolas Robidoux, Laurentian University 91 New ellipse clamping method and vertical/horizontal line preserving 92 filters for EWA resampling. Sped up resampling filter kernels. 93 94 Leonard Rosenthol 95 Authored the 'conjure' utility and associated MSL execution environment. 96 Provided MacOS support. Authored the CLIPBOARD, XCF, and PSD coders. 97 Postscript and PDF expertise. Significant drawing enhancements including 98 support for dash patterns, linecap stroking, clipping masks and a 99 mask image. 100 101 Kyle Shorter 102 Original author of PerlMagick. Author of the LOCALE coder. 103 104 Lars Ruben Skyum 105 Contributed the -clippath functionality, improved color profile support, 106 and re-wrote the PS3 coder. 107 108 Anthony Thyssen 109 Designed the ImageMagick 6.0 command line processing with parenthesis, 110 image sequence operators, and GIF animation processing. Wrote the 111 image perspective distortions (-distort) and resampling methods. 112 Maintains a comprehensive set of examples of using ImageMagick at 113 http://www.imagemagick.org/Usage/. 114 115 Milan Votava 116 Contributed support for Wireless BitMap, used in WAP - Wireless Access 117 Protocol. 118 119 120 We acknowledge these non-developer contributors to the ImageMagick project: 121 122 Hanno Bck 123 Contributed numerous fuzzed-images that revealed program flaws in 124 ImageMagick. Additional checks were added to guard against nefarious 125 image files. 126 127 Rod Bogart and John W. Peterson, University of Utah 128 Image compositing is loosely based on rlecomp of the Utah Raster Toolkit. 129 130 Thomas R Crimmins 131 Inventor of the eight hull algorithm used for speckle reduction. 132 133 Michael Halle, Spatial Imaging Group at MIT 134 Contributed the initial implementation of Alan Paeth's image rotation 135 algorithm. 136 137 Paul Heckbert, Carnegie Mellon University 138 Image resizing is loosely based on Paul Heckbert's Zoom program. 139 140 Peder Langlo, Hewlett Packard 141 Made hundreds of suggestions and bug reports. Without Peder, this 142 software would not be nearly as useful as it is today. 143 144 David Pensak, E. I. du Pont de Nemours and Company 145 For providing the computing environment that made developing ImageMagick 146 possible. 147 148 Paul Raveling, USC Information Sciences Institute 149 The spatial subdivision color reduction algorithm is based on his 150 Img software. 151 152 Alvy Ray Smith and Eric Ray Lyons 153 HWB color transform and algorithm. 154 155 Alexander Zimmermann 156 Responsible for the ImageMagick Linux binary distributions for many years. 157 His efforts are very much appreciated. 158
