Segment editor

See examples of using Segment editor effects from Python scripts in the script repository.

Effect parameters

Setting/getting effect parameters:

• Numeric or string parameter values: Common parameters must be set using setCommonParameter(parameterName, parameterValue) method, while effect-specific parameters can be set using setParameter(parameterName, parameterValue) method of the effect. Both common and effect-specific parameters can be retrieved using parameter(parameterName) method (for string or enum type), integerParameter(parameterName) (for int type), doubleParameter(parameterName) (for float type).

• Node reference (noderef type) parameter: It holds a reference to a node object, therefore it must be get/set by calling nodeReference(parameterName) and setNodeReference(parameterName, node) or setCommonNodeReference(parameterName, node) methods of the parameter set node.
