Method Detail

createFunctionalGroupsIfNotPresent

public static AttributeList createFunctionalGroupsIfNotPresent(AttributeList list,
                                               int numberOfFrames)

Create shared and per-frame functional group sequences if not already present.

Parameters:

list - an existing (possibly empty) attribute list, if null, a new one will be created; may already shared and per-frame functional group sequences or they will be added

numberOfFrames - return attribute list with empty per-frame and shared functional group sequences fadded

Throws:

DicomException
