Description
Alpha blend value to be applied to mixer. Provides 256 levels of
fixed alpha blending:
The AlphaSelect ROP must be set appropriately to use this feature.
Control how Alpha channel data is generated
Mode 11 is not effective when PF_10B_MODE is on since the Alpha
value is set to zero.
Controls alpha channel format within layer
The conversion takes place after the color key unit before the
undither unit.
Controls upper channel format within layer
The conversion takes place after the color key unit before the
undither unit.
Controls middle channel format within layer
The conversion takes place after the color key unit before the
undither unit.
Controls lower channel format within layer
The conversion takes place after the color key unit before the
undither unit
Defines pixel offset (in bytes) within a multi-pixel 64-bit word for
channel 2 for semi-planar and planar modes.
The number will be truncated to the closest even number for
channel 2
Defines pixel offset (in bytes) within a multi-pixel 64-bit word.
