Annotations allow one or more items of text to be added to each film printed (not each image). They are very printer-dependent, and many printers do not support them at all. The number and placement depend on the annotation format ID, which in DicomObjects should be placed, before the FilmBox is created in the AnnotationFormat property. Each DicomDataSet in this collection corresponds to one annotation, and they must be added with appropriate tags (2030,0010 for the ID and 2030,0020 for the text). Alternatively, the AddAnnotation method may be used.
