Pavel Krajcevski	ab0dbbfa6e	Bugfix ... The bug was that bitIdx was not being taken into account when we realized that there was enough pixel depth to stay within the current byte when reading pixel values.	2013-08-30 18:45:14 -04:00
Pavel Krajcevski	1cc8f57538	Add block tests	2013-08-30 18:44:50 -04:00
Pavel Krajcevski	90662a56cd	First pass at PVRTC Decompressor	2013-08-29 18:35:15 -04:00
Pavel Krajcevski	c59deae728	Add accessors for the color channels and a method for packing the information into a 32 bit RGBA int	2013-08-29 18:34:53 -04:00
Pavel Krajcevski	f822c15868	Pixel depth defaults to 8	2013-08-29 18:34:25 -04:00
Pavel Krajcevski	73f4992081	If we want a color channel with zero depth then it should default to full intensity, but we will remember that there is zero depth there.	2013-08-29 18:33:56 -04:00

Pavel Krajcevski	c5fb5ba0b1	Reorder color channels to match PVRTC spec	2013-08-29 11:57:18 -04:00
Pavel Krajcevski	53e7879742	Add PVRTC Pixel class ... This class accepts a pixels with up to 8-bit components. With the way PVRTC is laid out, there are many different bit modes that we could run into. This lets us change between any that we'd like to deal with.	2013-08-28 17:52:45 -04:00
Pavel Krajcevski	5c80b4f373	Initial files for PVRTC encoder. Starting with a decompressor.	2013-08-27 18:25:15 -04:00
