Member Function Documentation

ndk::ConstraintMatrixParams ConstrainOpI::getConstraintParametersFromKnobs ( const OutputContext * context = nullptr ) const

Returns a ConstraintMatrixParams structure populated from the knobs Does not populate xform variables as these are not obtained from the knobs.

bool ConstrainOpI::constraintMaintainOffset ( ) const

Gets whether we should be maintaining the offset given the constraint type and whether the maintain offset knob value is True.
