Member Function Documentation

◆ clone()

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

inlineoverridevirtual

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 43 of file GrModulateAtlasCoverageEffect.h.

                                                              {
        return std::make_unique<GrModulateAtlasCoverageEffect>(*this);
    }

◆ GR_DECL_BITFIELD_CLASS_OPS_FRIENDS()

GrModulateAtlasCoverageEffect::GR_DECL_BITFIELD_CLASS_OPS_FRIENDS ( Flags )

◆ name()

const char * GrModulateAtlasCoverageEffect::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 39 of file GrModulateAtlasCoverageEffect.h.

                                      {
        return "GrModulateAtlasCoverageFP";
