Detailed Description

Utility class for containing a color ramp.

Constructor & Destructor Documentation

UT_Ramp::UT_Ramp ( )
UT_Ramp::UT_Ramp ( const UT_Ramp copy)

Do not pass by value, you should be passing by const &. If you really need by value make the copy internally to your system.

WARNING: If building scalar ramps, set ALL the fvals to the same value. Code will randomly evaluate .r or .a

bool UT_Ramp::resolveOpRamp ( const char *  op_path,
const char *  ramp_parm,

int op_id = NULL,

Fetch the ramp from an OP node's ramp parm. May return false if the OP or parm is not found, if the parm is not a ramp, or if the UT_RampOpResolver is not assigned by setRampOpResolver(). is_rgb, op_id, and op_version are optional return values for the type of ramp, the parent node's unique ID, and the parent node's version parm serial (as reported by getVersionParms()).

Warning: If setting scalar ramps, make sure all of the fvals have the same value, as evaluators will pick a channel at whim.

Install an OP node resolver for ramp parameters. Required for resolveOpRamp() to work. OP_Director calls this.
