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 !...of PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, emails, images and more...

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....of PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, emails, images and more...

OCR support means the ability to connect an external module (library) for the recognition of printed text (optical character recognition, OCR) on images, either separate or embedded in documents.
To connect OCR, you need to implement the IOcrConnector interface in the client code.
The following example demonstrates how to implement the OCR connector using com.aspose.ocr library for text recognition in images.
