L_VOID LDicomAssociate::DelTransfer(nID, nIndex)
Deletes a Transfer Syntax from the specified Presentation Context.
Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.
The index of the Transfer Syntax to delete. This index is zero-based.
None.
A DICOM Associate (Request or Accept) can have multiple Presentation Contexts. A DICOM Associate Request can have multiple Transfer Syntax entries for each Presentation Context. A Transfer Syntax can be deleted by specifying the ID for the appropriate Presentation Context and the index for the appropriate Transfer Syntax.
