Comments
GML data contains the Geography Markup Language (GML) information for a single or multiple codestream. The primary role of GML in relation to JPEG 2000 is to provide an XML encoding of the metadata necessary to make the JPEG document a georeferenced or geographic image.
The L_JP2_GMLDATA structure is used in the following functions:
LJp2FileFormat::ReadGMLDataMemory
LJp2FileFormat::AppendGMLDataMemory
