Detailed Description

template<int R_LUM_BITS, int G_LUM_BITS, int B_LUM_BITS>
class SkTMaskPreBlend< R_LUM_BITS, G_LUM_BITS, B_LUM_BITS >

SkTMaskPreBlend is a tear-off of SkTMaskGamma. It provides the tables to convert a linear alpha value for a given channel to a gamma correcting alpha value for that channel. This class is immutable.

If fR, fG, or fB is nullptr, all of them will be. This indicates that no mask pre blend should be applied. SkTMaskPreBlend::isApplicable() is provided as a convenience function to test for the absence of this case.

Constructor & Destructor Documentation

SkTMaskPreBlend() [1/2]

template<int R_LUM_BITS, int G_LUM_BITS, int B_LUM_BITS>

SkTMaskPreBlend< R_LUM_BITS, G_LUM_BITS, B_LUM_BITS >::SkTMaskPreBlend ( )

inline

Creates a non applicable SkTMaskPreBlend.

: fParent(), fR(nullptr), fG(nullptr), fB(nullptr) { }

SkTMaskPreBlend() [2/2]

template<int R_LUM_BITS, int G_LUM_BITS, int B_LUM_BITS>

SkTMaskPreBlend< R_LUM_BITS, G_LUM_BITS, B_LUM_BITS >::SkTMaskPreBlend ( const SkTMaskPreBlend< R_LUM_BITS, G_LUM_BITS, B_LUM_BITS > &  that )

inline

This copy contructor exists for correctness, but should never be called when return value optimization is enabled.

isApplicable()

template<int R_LUM_BITS, int G_LUM_BITS, int B_LUM_BITS>

bool SkTMaskPreBlend< R_LUM_BITS, G_LUM_BITS, B_LUM_BITS >::isApplicable ( ) const

inline

True if this PreBlend should be applied. When false, fR, fG, and fB are nullptr.
