|
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)
|
|
|
|
|
2001-10-21 00:05:56 +00:00
|
|
|
Supported output formats BGR15 BGR16 BGR24 BGR32
|
2001-10-20 21:12:09 +00:00
|
|
|
BGR15 & BGR16 MMX verions support dithering
|
|
|
|
Special versions: fast Y 1:1 scaling (no interpolation in y direction)
