[−][src]Struct gba_hal::data::BlendAlpha
Controls alpha blend.
Both fields are x/16, but values above 16 are capped at 16/16.
For each color channel of an affected 1st target pixel with a valid 2nd target pixel the final channel value is as follows:
I = min(31, I_1st * EVA + I_2nd * EVB)
If the blend mode isn't set to AlphaBlend
, or if the 1st target and 2nd
target combination isn't valid for this pixel location then this register
has no effect at all.
