SaveAnnotations(string,int,int,MedicalViewerFileOperation) Method

Summary
Saves the annotation container(s) of a cell to a file.
Syntax
C#
C++/CLI
public void SaveAnnotations( 
   string fileName, 
   int subCellIndex, 
   int startPage, 
   MedicalViewerFileOperation operation 
) 
            public: 
void SaveAnnotations(  
   String^ fileName, 
   int subCellIndex, 
   int startPage, 
   MedicalViewerFileOperation operation 
)  

Parameters

fileName
A string that contains the path to the file 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.
