The application is open source, and the algorithm is in:
https://github.com/ForkandBeard/Alferd-Spritesheet-Unpacker/blob/master/ASU/BO/RegionUnpacker.cs While a pixel is not the background color the rectangle is increased - in X and Y. This is done in multiple threads, and then overlapping rectangles are combined. |
