Object data access function
#include "dip_measurement.h"
dip_Error dip_MeasurementObjectData ( measurement, featureID, objectID, data, verdict )
The MeasurementObjectData, MeasurementObjectValue and MeasurementFeatureDescription functions provide access to the functions that are registered by each measurement function. See also MeasurementFeatureRegister.
The Object data is the data allocated by a measurement function for internal purposes, for example to store intermediate results. Its format is free. Therefore, the use of this function is only meaningful for a particular measurement function itself. To access the measurement values of a measurement function, use MeasurementObjectValue.
The verdict parameter provides a means to test whether featureID or objectID are valid within the context of measurement. If one of them is invalid, and verdict is not zero, *verdict is set to DIP_FALSE, otherwise its value is DIP_TRUE. If verdict is zero, MeasurementObjectData produces an error when either featureID or objectID is invalid.
