Load an image Extract the root metadata package Use the FileType property to obtain file format information AdvancedUsage.ManagingMetadataForSpecificFormats.Image.ImageReadFileFormatProperties
using (Metadata metadata = new Metadata(Constants.InputPng)) { var root = metadata.GetRootPackage(); Console.WriteLine(root.FileType.FileFormat); Console.WriteLine(root.FileType.ByteOrder); Console.WriteLine(root.FileType.MimeType); Console.WriteLine(root.FileType.Extension); Console.WriteLine(root.FileType.Width); Console.WriteLine(root.FileType.Height); } More resources GitHub examples You may easily run the code above and see the feature in action in our GitHub examples:...Annotation Product Solution GroupDocs.Conversion Product Solution GroupDocs...
