Hi Andrea, The RecursiveParserWrapper, as you found, is only for extracted content and metadata. It was designed to cache metadata and content from embedded documents so that you can easily keep those two things together for each embedded document.
To extract the raw bytes from embedded files, try implementing an EmbeddedDocumentExtractor and passing that into the ParseContext. Take a look at http://svn.apache.org/repos/asf/tika/trunk/tika-server/src/main/java/org/apache/tika/server/resource/UnpackerResource.java and specifically the inner class MyEmbeddedDocument extractor for an example. As another example, look at http://svn.apache.org/repos/asf/tika/trunk/tika-app/src/main/java/org/apache/tika/cli/TikaCLI.java, and specifically the inner class: FileEmbeddedDocumentExtractor Basically, in ParseEmbedded, just copy the InputStream to a FileOutputStream, and you should be good to go. public boolean shouldParseEmbedded(Metadata metadata) { return true; } public void parseEmbedded(InputStream inputStream, ContentHandler contentHandler, Metadata metadata, boolean b) throws SAXException, IOException { Best, Tim From: Andrea Asta [mailto:asta.and...@gmail.com] Sent: Monday, July 06, 2015 6:11 AM To: user@tika.apache.org Subject: Extract PDF inline images Hello, I'm trying to store the inline images from a PDF to a local folder, but can't find any valid example. I can only use the RecursiveParserWrapper to get all the available metadata, but not the binary image content. This is my code: RecursiveParserWrapper parser = new RecursiveParserWrapper( new AutoDetectParser(), new BasicContentHandlerFactory(HANDLER_TYPE.XML, -1) ); Metadata metadata = new Metadata(); ParseContext context = new ParseContext(); PDFParserConfig config = new PDFParserConfig(); PDFParser p; config.setExtractInlineImages(true); config.setExtractUniqueInlineImagesOnly(false); context.set(org.apache.tika.parser.pdf.PDFParserConfig.class, config); context.set(org.apache.tika.parser.Parser.class, parser); InputStream is = PdfRecursiveExample.class.getResourceAsStream("/BA200PDE.PDF"); //parsing the file ToXMLContentHandler handler = new ToXMLContentHandler(new FileOutputStream(new File("out.txt")), "UTF-8"); parser.parse(is, handler, metadata, context); How can I store each image file to a folder? Thanks Andrea
