Syntax
C#
VB
C++
public void SaveAnnotations( 
   Stream stream, 
   int subCellIndex, 
   int startPage, 
   MedicalViewerFileOperation operation 
) 
  
Public Overloads Sub SaveAnnotations( _ 
   ByVal stream As Stream, _ 
   ByVal subCellIndex As Integer, _ 
   ByVal startPage As Integer, _ 
   ByVal operation As MedicalViewerFileOperation _ 
)  
            public: 
void SaveAnnotations(  
   Stream^ stream, 
   int subCellIndex, 
   int startPage, 
   MedicalViewerFileOperation operation 
)

Parameters

stream
A System.IO.Stream that to which to save the annotation container.

subCellIndex
The zero-based index of the sub-cell that contains the annotation container to be saved.

startPage
The page number of a multipage 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.
