Member Function Documentation

◆ appendStages()

bool SkComposeColorFilter::appendStages	(	const SkStageRec &	rec,
		bool	shaderIsOpaque
	)		const

overridevirtual

Implements SkColorFilterBase.

Definition at line 29 of file SkComposeColorFilter.cpp.

                                                                                        {

        innerIsOpaque = false;
    }
    return fInner->appendStages(rec, shaderIsOpaque) && fOuter->appendStages(rec, innerIsOpaque);
}

◆ flatten()

void SkComposeColorFilter::flatten ( SkWriteBuffer & ) const

overrideprotectedvirtual

Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).

DEPRECATED public : will move to protected ... use serialize() instead

Reimplemented from SkFlattenable.

Definition at line 37 of file SkComposeColorFilter.cpp.

    buffer.writeFlattenable(fOuter.get());
    buffer.writeFlattenable(fInner.get());

◆ inner()

sk_sp< SkColorFilterBase > SkComposeColorFilter::inner ( ) const

inline

Definition at line 28 of file SkComposeColorFilter.h.

28{ return fInner; }

◆ onIsAlphaUnchanged()

bool SkComposeColorFilter::onIsAlphaUnchanged ( ) const

overridevirtual

Returns the flags for this filter. Override in subclasses to return custom flags.

Reimplemented from SkColorFilterBase.

Definition at line 24 of file SkComposeColorFilter.cpp.

                                                    {
    // Can only claim alphaunchanged support if both our proxys do.
    return fOuter->isAlphaUnchanged() && fInner->isAlphaUnchanged();
}

◆ outer()

sk_sp< SkColorFilterBase > SkComposeColorFilter::outer ( ) const

inline

Definition at line 27 of file SkComposeColorFilter.h.

◆ type()

SkColorFilterBase::Type SkComposeColorFilter::type ( ) const

inlineoverridevirtual

Implements SkColorFilterBase.

Definition at line 25 of file SkComposeColorFilter.h.

25{ return SkColorFilterBase::Type::kCompose; }
