Reading PNG metadata properties The GroupDocs.Metadata API supports extracting format-specific information from PNG images.
The following are the steps to read the native PNG metadata.
Load a PNG image Get the root metadata package Extract the native metadata package using PngRootPackage.PngPackage Read the PNG metadata properties AdvancedUsage.ManagingMetadataForSpecificFormats.Image.Png.PngReadTextChunks
using (Metadata metadata = new Metadata(Constants.InputPng)) { var root = metadata.GetRootPackage(); foreach (var chunk in root.PngPackage.TextChunks) { Console.WriteLine(chunk.Keyword); Console.WriteLine(chunk.Text); var compressedChunk = chunk as PngCompressedTextChunk; if (compressedChunk !...You are welcome to view and edit metadata of PDF, DOC, DOCX,...

Reading MOV format-specific properties The GroupDocs.Metadata API supports extracting QuickTime atoms from a MOV video. The atom is the basic data unit in any QuickTime file. Please find more information on QuickTime atoms in the official specification: https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFPreface/qtffPreface.html

Not all metadata properties extracted from a file are marked with tags. Some file formats and metadata standards allow adding fully custom properties that can’t be properly tagged by the library since their purpose is not clearly defined in the appropriate format/standard specification. In such cases, you can use the name of the property to locate and remove it. The following example demonstrates some advanced usage scenarios of the GroupDocs.Metadata search engine allowing to remove metadata properties....You are welcome to view and edit metadata of PDF, DOC, DOCX,...

For all supported image formats the GroupDocs.Metadata API allows extracting common image properties such as width and height, MIME type, byte order, etc. Please see the code snippet below for more information on the feature.
Load an image Extract the root metadata package Use the getImageType method to obtain file format information advanced_usage.managing_metadata_for_specific_formats.image.ImageReadFileFormatProperties
try (Metadata metadata = new Metadata(Constants.InputPng)) { ImageRootPackage root = metadata.getRootPackageGeneric(); System.out.println(root.getImageType().getFileFormat()); System.out.println(root.getImageType().getByteOrder()); System.out.println(root.getImageType().getMimeType()); System.out.println(root.getImageType().getExtension()); System.out.println(root.getImageType().getWidth()); System.out.println(root.getImageType().getHeight()); } More resources GitHub examples You may easily run the code above and see the feature in action in our GitHub examples:...You are welcome to view and edit metadata of PDF, DOC, DOCX,...
