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.getPngPackage Read the PNG metadata properties advanced_usage.managing_metadata_for_specific_formats.image.png.PngReadTextChunks
try (Metadata metadata = new Metadata(Constants.InputPng)) { PngRootPackage root = metadata.getRootPackageGeneric(); for (PngTextChunk chunk : root.getPngPackage().getTextChunks()) { System.out.println(chunk.getKeyword()); System.out.println(chunk.getText()); if (chunk instanceof PngCompressedTextChunk) { PngCompressedTextChunk compressedChunk = (PngCompressedTextChunk) chunk; System....You are welcome to view and edit metadata of PDF, DOC, DOCX,...
