DiffImg 1.5.0

DiffImg is a simple image comparison tool which take two images with the same size as input. Some statitics are computed and the positions where pixel differ are displayed as a color mask.

Why check for image difference ?

• Compression level comparison
• Raytracing parametrization optimisation
• Non regression tests for 3D engine
• Just for fun, while playing games etc.

DifffImg use QImage as inner format so it has been tested only on RGB image, so alpha channel or float texture aren't take into account. Because DiffImg is written with Qt, it runs on Windows and Linux (MacOSX isn't tested yet). It can read basic formats as BMP, PNG, JPG. You can add more formats if needed by using bridge plugins to the FreeImage or the Devil libraries.
