BlendModeCoeff

class BlendModeCoeff

For Porter-Duff SkBlendModes (those <= kLastCoeffMode), these coefficients describe the blend equation used.

Coefficient-based blend modes specify an equation: (‘dstCoeff’ * dst + ‘srcCoeff’ * src), where the coefficient values are constants, functions of the src or dst alpha, or functions of the src or dst color.

Members:

kZero : 0

kOne : 1

kSC : src color

kISC : inverse src color (i.e. 1 - sc)

kDC : dst color

kIDC : inverse dst color (i.e. 1 - dc)

kSA : src alpha

kISA : inverse src alpha (i.e. 1 - sa)

kDA : dst alpha

kIDA : inverse dst alpha (i.e. 1 - da)
