| | | | | | | | | | | | All functions do 2 pixels at a time. 90 and 270 rotations implemented. YV16 refactored. YV12 code accepts a YuvType that allows the same code to support YV16 as well. Special case for half size removed. Special case for doubling added. 3.62 ms versus 8.62 for general purpose code.

* YUV to RGB with arbitrary scaling.fbarchard@chromium.org2009-04-211-29/+30
| | | | | | | | | | | Semi-optimized C code achieving 33 ms for 1080 double sized or 9 ms with openmp enabled. Special case half size which is much faster. Future versions will support mirror and perhaps rotate. (mirror is free) Future versions will be MMX assembly for speed.

This will be used for reference. Its reasonably simple, fast and high quality. Future versions will be optimized and should try to maintain similar quality. Longer term we may move this to Skia or attempt a hardware version.
