Function Documentation

RE_API bool RE_Utils::createRampFromParm	(	const UT_StringHolder &	parm_path,
		const UT_StringHolder &	rel_path,
		UT_Vector4FArray &	ramp_data,
		int &	op_id,
		int &	op_version,
		bool &	is_rgb
	)

Given an oppath + a channel name (op:/path/to/node/parmname) to a ramp parm, generate a ramp in ramp_data. Presize the array to the precision you require. parm_path can also be op:parmname if rel_path is the path to the node.
