this class implements a sequence of pixel items, i.e.
the data structure DICOM is using to store compressed pixel data. The object behaves very much like a sequence, but uses the pixel data tag (7FE0,0010) and OB value representation with undefined length, and the "items" contained within the sequence are in fact pixel items (class DcmPixelItem) that contain no list of DICOM elements but raw compressed pixel data.

Virtual object copying.
This method can be used for DcmObject and derived classes to get a deep copy of an object. Internally the assignment operator is called if the given DcmObject parameter is of the same type as "this" object instance. If not, an error is returned. This function permits copying an object by value in a virtual way which therefore is different to just calling the assignment operator of DcmElement which could result in slicing the object.
