◆ clone()

std::unique_ptr< GrFragmentProcessor > GrColorSpaceXformEffect::clone ( ) const

overridevirtual

Makes a copy of this fragment processor that draws equivalently to the original. If the processor has child processors they are cloned as well.

Implements GrFragmentProcessor.

Definition at line 101 of file GrColorSpaceXform.cpp.

                                                                        {
    return std::unique_ptr<GrFragmentProcessor>(new GrColorSpaceXformEffect(*this));
}

◆ colorXform()

const GrColorSpaceXform * GrColorSpaceXformEffect::colorXform ( ) const

inline

Definition at line 81 of file GrColorSpaceXform.h.

◆ constantOutputForConstantInput()

SkPMColor4f GrColorSpaceXformEffect::constantOutputForConstantInput ( const SkPMColor4f & input ) const

overrideprivatevirtual

Reimplemented from GrFragmentProcessor.

Definition at line 153 of file GrColorSpaceXform.cpp.

                                        {
    const auto c0 = ConstantOutputForConstantInput(this->childProcessor(0), input);
    return this->fColorXform->apply(c0.unpremul()).premul();
}

◆ Make() [1/3]

std::unique_ptr< GrFragmentProcessor > GrColorSpaceXformEffect::Make	(	std::unique_ptr< GrFragmentProcessor >	child,
		const GrColorInfo &	srcInfo,
		const GrColorInfo &	dstInfo
	)

static

Definition at line 166 of file GrColorSpaceXform.cpp.

                                    {
    return Make(std::move(child), GrColorSpaceXform::Make(srcInfo, dstInfo));
}

◆ Make() [2/3]

std::unique_ptr< GrFragmentProcessor > GrColorSpaceXformEffect::Make	(	std::unique_ptr< GrFragmentProcessor >	child,
		sk_sp< GrColorSpaceXform >	colorXform
	)

static

Returns a fragment processor that calls the passed in FP and then converts it with the given color xform. If the child is null, fInputColor is used. Returns child as-is if the xform is null (i.e. a no-op).

Definition at line 173 of file GrColorSpaceXform.cpp.

                                             {

◆ Make() [3/3]

std::unique_ptr< GrFragmentProcessor > GrColorSpaceXformEffect::Make	(	std::unique_ptr< GrFragmentProcessor >	child,
		SkColorSpace *	src,
		SkAlphaType	srcAT,
		SkColorSpace *	dst,
		SkAlphaType	dstAT
	)

static

Returns a fragment processor that calls the passed in fragment processor, and then converts the color space of the output from src to dst. If the child is null, fInputColor is used.

Definition at line 159 of file GrColorSpaceXform.cpp.

                                              {
    return Make(std::move(child), GrColorSpaceXform::Make(src, srcAT, dst, dstAT));
}

◆ name()

const char * GrColorSpaceXformEffect::name ( ) const

inlineoverridevirtual

Human-meaningful string to identify this processor; may be embedded in generated shader code and must be a legal SkSL identifier prefix.

Implements GrProcessor.

Definition at line 78 of file GrColorSpaceXform.h.

78{ return "ColorSpaceXform"; }

◆ onAddToKey()

void GrColorSpaceXformEffect::onAddToKey	(	const GrShaderCaps &	,

    b->add32(GrColorSpaceXform::XformKey(fColorXform.get()));
}

◆ onIsEqual()

bool GrColorSpaceXformEffect::onIsEqual ( const GrFragmentProcessor & ) const

overrideprivatevirtual

Subclass implements this to support isEqual(). It will only be called if it is known that the two processors are of the same subclass (i.e. have the same ClassID).

Implements GrFragmentProcessor.

Definition at line 105 of file GrColorSpaceXform.cpp.

                                                                          {
    const GrColorSpaceXformEffect& other = s.cast<GrColorSpaceXformEffect>();

}

◆ onMakeProgramImpl()

std::unique_ptr< GrFragmentProcessor::ProgramImpl > GrColorSpaceXformEffect::onMakeProgramImpl ( ) const

overrideprivatevirtual

Returns a new instance of the appropriate ProgramImpl subclass for the given GrFragmentProcessor. It will emit the appropriate code and live with the cached program to setup uniform data for each draw that uses the program.

Implements GrFragmentProcessor.
