In testing some computer vision stuff I was writing, I found that mask.get_bounding_rects() often split a connected component into multiple bounding boxes. Specifically in the following case:
0011 1111 It would split the 11 in the first row and the 1111 in the second row into separate connected components, and therefore separate bounding boxes. I wrote a new version of it based on the algorithm I used in mask.connected_component. It correctly detects connected components, and there is also a side benefit of an, on average, 2x increase in performance. I attached the functions that I changed, and the full mask.c is available in my repo, though it also contains other functions that I'm proposing for 1.9. http://git.n0r.org/?p=pygame-nrp;a=blob;f=src/mask.c Nirav
