Comments

LEAD Annotation files can be saved as private data in a DICOM data set (LEAD native format or binary encoded format). There can be up to 256 private data tags for LEAD annotation files. 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);
