Member Function Documentation

◆ clone()

std::unique_ptr< GrFragmentProcessor > GrMatrixEffect::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 78 of file GrMatrixEffect.cpp.

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

◆ constantOutputForConstantInput()

SkPMColor4f GrMatrixEffect::constantOutputForConstantInput ( const SkPMColor4f & inputColor ) const

inlineoverrideprivatevirtual

Reimplemented from GrFragmentProcessor.

Definition at line 46 of file GrMatrixEffect.h.

                                                                                             {
        return ConstantOutputForConstantInput(this->childProcessor(0), inputColor);
    }

◆ Make()

std::unique_ptr< GrFragmentProcessor > GrMatrixEffect::Make	(	const SkMatrix &	matrix,
		std::unique_ptr< GrFragmentProcessor >	child
	)

static

Definition at line 21 of file GrMatrixEffect.cpp.

                                                                          {

        auto me = static_cast<GrMatrixEffect*>(child.get());

        // so we can't add perspective to 'me' if it doesn't already have it.

        }
    }
    return std::unique_ptr<GrFragmentProcessor>(new GrMatrixEffect(matrix, std::move(child)));
}

◆ name()

const char * GrMatrixEffect::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 30 of file GrMatrixEffect.h.

30{ return "MatrixEffect"; }

◆ onAddToKey()

void GrMatrixEffect::onAddToKey	(	const GrShaderCaps &	caps,
		skgpu::KeyBuilder *	b
	)		const

overrideprivatevirtual

Implements GrFragmentProcessor.

Definition at line 66 of file GrMatrixEffect.cpp.

66{}

◆ onIsEqual()

bool GrMatrixEffect::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 68 of file GrMatrixEffect.cpp.

                                                                     {

}

◆ onMakeProgramImpl()

std::unique_ptr< GrFragmentProcessor::ProgramImpl > GrMatrixEffect::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.

Definition at line 35 of file GrMatrixEffect.cpp.
