Appends Geography Markup Language (GML) data to the specified JPEG 2000 data stream. This method is available in the Document/Medical Toolkits.

Syntax

Visual Basic (Declaration)
Public Overloads Sub AppendGmlData( _ ByVal stream As Stream, _ ByVal gmlData As GmlData _ )

Visual Basic (Usage)	Copy Code
`Dim instance As Jpeg2000Engine Dim stream As Stream Dim gmlData As GmlData instance.AppendGmlData(stream, gmlData)`

C#
public void AppendGmlData( Stream stream, GmlData gmlData )

C++/CLI
public: void AppendGmlData( Stream^ stream, GmlData^ gmlData )

Parameters

stream: A Stream containing the JPEG 2000 file data to which the GML data is being appended.
gmlData: GmlData object containing the GML information being appended.
