Comments

You can add a Context Group to the Context Group Table either by loading it from the internal table maintained by LEADTOOLS or by inserting it directly into the Context Group Table. The Context Groups in the internal table are those defined by the DICOM Content Mapping Resource (DCMR). For a list of possible values, refer to Context Identifier Values. Use the Load function to load the desired Context Groups from this table into the Context Group Table. To insert a Context Group, call the LDicomContextGroup::Insert function.

If the Context Group Table already contains a Context Group with the specified Context ID, the function will just return successfully. If the parameter pszContextID is set to NULL, the function will load all the Context Groups that are not loaded currently, without affecting any Context Group that is already in the Context Group Table. (Therefore, to load all of the Context Groups in the internal table from the beginning, call the function with the pszContextID parameter set to NULL.)

A return value of DICOM_ERROR_PARAMETER indicates that the internal table does not contain a Context Group with the specified Context ID.
