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.

78 {
79 return std::unique_ptr<GrFragmentProcessor>(new GrMatrixEffect(*this));
80}

◆ Make()

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

Definition at line 21 of file GrMatrixEffect.cpp.

24 auto me = static_cast<GrMatrixEffect*>(child.get());
25 // registerChild's sample usage records whether the matrix used has perspective or not,
26 // so we can't add perspective to 'me' if it doesn't already have it.

28 me->fMatrix.preConcat(matrix);

◆ 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.
