Reading JPEG2000 comments The GroupDocs.Metadata API supports extracting format-specific information from JPEG2000 images.
The following are the steps to read the JPEG2000 comments (pieces of metadata represented as strings with the length up to 64 kbytes).
Load a JPEG2000 image Get the root metadata package Extract the native metadata package using the Jpeg2000RootPackage.getJpeg2000Package method Read the JPEG2000 comments advanced_usage.managing_metadata_for_specific_formats.image.jpeg2000.Jpeg2000ReadComments
