LDicomDS::AnnDelete can delete a page from an annotation file, delete the entire annotation file, or delete all annotation files in a DICOM data set.
To delete the third page of the annotation file at index 1:
LDicomDS DicomDS;
DicomDS.LoadDS("d:\\work\\images\\a.dic", 0);
DicomDS.AnnDelete(1, 3);
To delete the annotation file at index 1
LDicomDS DicomDS;
DicomDS.LoadDS ("d:\\work\\images\\a.dic", 0);
DicomDS.AnnDelete(1, -1);
To delete all annotation files and the private creator data element
LDicomDS DicomDS;
DicomDS.LoadDS ("d:\\work\\images\\a.dic", 0);
DicomDS.AnnDelete(-1, 0);
