Working with metadata in JPEG2000 images Leave feedback

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).

1. Load a JPEG2000 image
2. Get the root metadata package
3. Extract  the native metadata package using Jpeg2000RootPackage.Jpeg2000Package
4. Read the JPEG2000 comments

AdvancedUsage.ManagingMetadataForSpecificFormats.Image.Jpeg2000.Jpeg2000ReadComments

using (Metadata metadata = new Metadata(Constants.InputJpeg2000))
{
	var root = metadata.GetRootPackage<Jpeg2000RootPackage>();
	if (root.Jpeg2000Package.Comments != null)
	{
		foreach (var comment in root.Jpeg2000Package.Comments)
		{
			Console.WriteLine(comment);
		}
	}
}

GroupDocs.Metadata for .NET also allows managing XMP metadata in JPEG2000 images. For more details please refer to the following guide: Working with XMP metadata.

The GroupDocs.Metadata API supports handling EXIF metadata in JPEG images. Please find appropriate code samples in the Working with EXIF metadata section.

You may easily run the code above and see the feature in action in our GitHub examples:

• GroupDocs.Metadata for .NET examples
• GroupDocs.Metadata for Java examples

Along with full featured .NET library we provide simple, but powerful free Apps. You are welcome to view and edit metadata of PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, emails, images and more with our free online Free Online Document Metadata Viewing and Editing App.
