NOTES |
|
|
|
known BUGS with known cause (no bugreports please!, but patches are welcome :) ) |
|
horizontal MMX2 scaler reads 1-7 samples too much (might cause a sig11) |
|
|
|
Supported output formats BGR15 BGR16 BGR24 BGR32 |
|
BGR15 & BGR16 MMX verions support dithering |
|
Special versions: fast Y 1:1 scaling (no interpolation in y direction) |
|
|
|
TODO |
|
more intelligent missalignment avoidance for the horizontal scaler |
|
bicubic scaler |
|
dither in C |
|
change the distance of the u & v buffer |
