Enum values
CLEAR
enum val CLEAR : BlendModeCompat
Destination pixels covered by the source are cleared to 0.
\(\alpha_{out} = 0\)
\(C_{out} = 0\)
COLOR
@RequiresApi(29) enum val COLOR : BlendModeCompat
Replaces hue and saturation of destination with hue and saturation of source, leaving luminosity unchanged.
COLOR_BURN
@RequiresApi(29) enum val COLOR_BURN : BlendModeCompat
Makes destination darker to reflect source.
\(\alpha_{out} = \alpha_{src} + \alpha_{dst} - \alpha_{src} * \alpha_{dst}\)
\begin{equation} C_{out} = \begin{cases} C_{dst} + C_{src}*(1 - \alpha_{dst}) & C_{dst} = \alpha_{dst} \\ \alpha_{dst}*(1 - \alpha_{src}) & C_{src} = 0 \\ \alpha_{src}*(\alpha_{dst} - min(\alpha_{dst}, (\alpha_{dst} - C_{dst})*\alpha_{src}/C_{src})) + C_{src} * (1 - \alpha_{dst}) + \alpha_{dst}*(1-\alpha_{src}) & otherwise \end{cases} \end{equation}
