Pavel Krajcevski	a80944901e	Refactor CompressionJob struct. ... In order to better facilitate the change from block stream order to non-block stream order, a lot of changes were introduced to the way that we feed texture data to the compressors. This data is embodied in the CompressionJob struct. We have made it so that the compression job points to both the in and out pointers for our compressed and uncompressed data. Furthermore, we have made sure that the struct also contains the format that its compressing for, so that if any threading programs would like to chop up a compression job into smaller chunks based on the format, it doesn't need to know the format explicitly, it just needs to know certain properties about the format. Moreover, the user can now define the start and end pixels from which we would like to compress to. We can compress subsets of data by changing the in and out pointers and the width and height values. The compressors will read data linearly until they reach the out pixels based on the width of the given pixel.	2013-11-08 16:31:19 -05:00
Pavel Krajcevski	29bd1368e6	Fix a few compiler warnings and add the BPTCEncoder license.	2013-09-15 14:56:09 -04:00
Pavel Krajcevski	09b5680245	Some small code style fixes	2013-09-06 13:37:50 -04:00
Pavel Krajcevski	b8e155e11c	Switch red and blue channels in our decompressor test.	2013-09-05 14:49:08 -04:00
Pavel Krajcevski	abd4ba8b54	Abstract away some utilities that we can use across all of our tests, and add a test for a gray image. The test currently seems to be failing, which is likely due to a bug in our bit depth manipulation code.	2013-09-04 20:20:37 -04:00
Pavel Krajcevski	bb525ae9dc	If all of the PVR blocks are the same then we don't need so much code.	2013-09-04 15:28:51 -04:00
Pavel Krajcevski	9273625eeb	Add initial decompressor test	2013-09-02 19:14:50 -04:00
