Pavel Krajcevski f7404c44b9 Refactor debug output for modulation info. 2013-09-12 15:01:19 -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.

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
Pavel Krajcevski 34ab853a62 Make sure to take into account the interleaved nature of the blocks when decompressing 2013-09-04 20:18:03 -04:00
