public void Save( 
   string fileName,
   AnnContainer[] containers,
   AnnCodecsFormat format
)

'Declaration
 
Public Overloads Sub Save( _
   ByVal fileName As String, _
   ByVal containers() As AnnContainer, _
   ByVal format As AnnCodecsFormat _
)

'Usage
 
Dim instance As AnnCodecs
Dim fileName As String
Dim containers() As AnnContainer
Dim format As AnnCodecsFormat
 
instance.Save(fileName, containers, format)

public:
void Save( 
   String^ fileName,
   array<AnnContainer^>^ containers,
   AnnCodecsFormat format
)

Parameters

fileName: The output file name.
containers: An array of AnnContainer containing the objects to be saved.
format: An AnnCodecsFormat value that specifies the annotation format to use when saving.

This method saves the entire array of AnnContainer as a multipage annotation file, with each page corresponding to one of the AnnContainer. If fileName already exists, it will be overwritten. If containers contain many AnnContainer, then this method will create the multipage annotation file much faster than repeated calls to Save(String,AnnContainer,AnnCodecsFormat,Int32,AnnCodecsSavePageMode)

This method only supports the AnnCodecsFormat.Xml format. All other AnnCodecsFormat are not supported.

For more information, refer to Annotation Files.
