AppendGmlData(Stream,GmlData) Method

Show in webframe
Example 





A System.IO.Stream containing the JPEG 2000 file data to which the GML data is being appended.
GmlData object containing the GML information being appended.
Appends Geography Markup Language (GML) data to the specified JPEG 2000 data stream. This method is available in the Document/Medical Toolkits.
