Coverity was used (free of charge) to perform static code analysis of the software. After resolving many issues, there are now zero reported defects per 1000 lines of code.
American fuzzy lop was used (by many) to produce and discover many of the files which caused problems for the software.
QuickFuzz was used (by Gustavo Grieco) to discover issues in the SVG renderer. QuickFuzz provides specific support for a set of file formats and is very good at chasing down and isolating weaknesses.
AddressSanitizer (ASan) was used to detect and isolate memory access issues.
Valgrind was used to detect and isolate memory access issues as well as memory leaks.
For providing the computing environment that made developing ImageMagick possible.
Responsible for the ImageMagick Linux binary distributions for many years. His efforts are very much appreciated.
Image resizing is based on Paul Heckbert's Zoom program.
The spatial subdivision color reduction algorithm is based on his Img software.
For the initial implementation of Alan Paeth's image rotation algorithm.
Made hundreds of suggestions and bug reports. Without Peder, this software would not be nearly as useful as it is today.
Image compositing is loosely based on rlecomp of the Utah Raster Toolkit.
HWB color transform and algorithm.
Inventor of the eight hull algorithm used for speckle reduction.
