See Also  Example
Leadtools.MedicalViewer Namespace > MedicalViewerCell Class > SaveAnnotations Method : SaveAnnotations(Stream,Int32,Int32,MedicalViewerFileOperation) Method



stream
A Stream that to which to save the annotation container.
subCellIndex
Index of the sub-cell that contains the annotation container to be saved.
startPage
The page number of a multi-page file, which can contain more than one annotation container. When saving a file, any value greater than the total number of pages will cause the saved annotation container to be appended to the end of the file.
operation
An enumerated MedicalViewerFileOperation value that indicates the operation to be taken on the file when saving the annotation container.
Saves the annotation container(s) of a cell to a file.
