Pavel Krajcevski	1b073eb4b7	Add 2BPP decompression	2013-09-12 14:45:56 -04:00
Pavel Krajcevski	b3f8fcd454	Decouple upscale directions so that we can non-uniformly scale images.	2013-09-12 14:44:54 -04:00
Pavel Krajcevski	dd625fca71	When going from 344(3/4) pixels to 4555, the alpha channel only has a zero appended to it. Hence we must clear that bit for each pixel that was transparent during decoding.	2013-09-10 13:22:53 -04:00
Pavel Krajcevski	eb312ccb0a	Small refactor	2013-09-09 14:16:45 -04:00
Pavel Krajcevski	0d0c65f536	Actually index into our pixels properly...	2013-09-06 01:55:25 -04:00
Pavel Krajcevski	2263080faa	Fix the interleaving by doing it when we're actually reading in the blocks	2013-09-06 01:55:06 -04:00
Pavel Krajcevski	db914018f1	Two enhancements: ... 1. Make sure to use the same lerping code for both modulation modes when decompressing. 2. Accept a flag during decompression that outputs the debug images that were computed during decompression.	2013-09-06 01:53:10 -04:00
Pavel Krajcevski	a6e6138084	Change the lerp function to be more explicit.	2013-09-05 14:49:56 -04:00
Pavel Krajcevski	669b2c0934	Reverse the order for modulating our bits... I'm not convinced that this is right	2013-09-04 20:18:43 -04:00
