All the test images can be seen here: + + http://entropymine.com/jason/bmpsuite/bmpsuite/html/bmpsuite.html + +The code used to generate the test images is available here: + + https://github.com/jsummers/bmpsuite/ + +The readme.txt file states that the code is GPLv3 and the generated image files +are in the public domain. We have not included the code, but we have included: +(a) some quotes from the documentation and (b) some of the reference PNG +images. However, (a) and (b) are for testing purposes only and are not included +in Firefox releases. + +The BMP files within this directory were generated with bmpsuite v2.3 (git +revision 3adcc9e20c0b6d2d665966b7e047b6f9474cef12). + +There are three sub-directories. +- g/: for "good" images. +- q/: for "questionable" images. +- b/: for "bad" images. +- x/: for images that arguably may not truly be in "BMP format". + +Each file listed in a reftest.list file is annotated with the following lines. + +- The first line starts with "BMP:" and is the output of the MOZ_LOG call in + nsBMPDecoder.cpp. It has basic image info. + +- Next is a quote from the bmpsuite docs, which describes the particulars of + the file. + +- Some files also have additional notes in square brackets. These explain + anything non-obvious about the file, such as how we handle things that are + ambiguous, any shortcomings in our decoding, and how Chromium handles the + image. + +Some of the reference PNGs need a small amount of fuzziness to match the BMPs. +This might be due to PNG color correction. + |
