Pavel Krajcevski	4135e38f22	Set the default wrap behavior to wrap for image upscale, too	2013-09-18 18:00:59 -04:00
Pavel Krajcevski	b3de3f2c01	If our compile flag is set to output debug images with tests, then actually do it.	2013-09-12 14:45:42 -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	7184d49ccd	Add unpack RGBA for our pixels	2013-09-12 14:41:00 -04:00
Pavel Krajcevski	1115c2f9e4	Add 2BPP helper functions for our blocks. ... Namely, there are two things that we need to do: 1. Figure out the sub-mode based on the mode bit and the structure of the modulation data. The comments in Block.h describe how we do this. 2. For a given texel index, return 2BPP texel modulation bits.	2013-09-12 14:30:08 -04:00
Pavel Krajcevski	08cad3ba86	Add 2BPP tests	2013-09-12 14:04:20 -04:00
Pavel Krajcevski	0172df4e60	Add final opaque to transparent gradient test.	2013-09-10 13:34:13 -04:00
Pavel Krajcevski	f5e0aa4f9f	Make sure to clear the MSBs of channels that have zero depth that get converted to higher depth values	2013-09-10 13:21:48 -04:00
Pavel Krajcevski	77bb7488cc	Fix typo	2013-09-10 11:58:53 -04:00
Pavel Krajcevski	5020f81f00	Add a transparent pvr image test	2013-09-09 10:33:04 -05:00
Pavel Krajcevski	09b5680245	Some small code style fixes	2013-09-06 13:37:50 -04:00
Pavel Krajcevski	5ac6872dc7	Add a test to make sure that after a bilerp the pixels that should remain unaffected do in fact remain unaffected.	2013-09-06 02:02:34 -04:00
Pavel Krajcevski	3806efe6fc	Add some more hacky includes to be able to output debug images from our tests.	2013-09-06 02:02:02 -04:00
Pavel Krajcevski	b8e155e11c	Switch red and blue channels in our decompressor test.	2013-09-05 14:49:08 -04:00
Pavel Krajcevski	7b72a84d87	Add a working directory for PVR lib tests ... Unfortunately, the WORKING_DIRECTORY directive for ADD_TEST seems to be broken as of CMake 2.8.10, fortunately there was a mail thread about this issue in 2.6 so I was able to implement the workaround.	2013-09-04 20:43:49 -04:00
Pavel Krajcevski	6149c0af3a	Add PVR tests ... If cmake was able to find Imagination's PVR library, then it'd be nice to make sure that our decompressor matches theirs. We incur a bit of overhead by adding .pvr files into git, but hopefully this cost will be beneficial to actually figuring out how things are working...	2013-09-04 20:21:56 -04:00
Pavel Krajcevski	052157ea49	Rename our tests to start with the prefix 'Test'	2013-09-04 20:21:28 -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
Pavel Krajcevski	4bbd80aab2	Make sure to preserve bit depth when bilinearly upscaling	2013-09-02 19:14:31 -04:00

Pavel Krajcevski	5cde88d3b7	Add Image tests	2013-08-31 18:31:38 -04:00
