Hi Tim,
thanks for your response, but I can't find a complete solution.
I've created a class using the same FileEmbeddedDocumentExtractor from
TikaCLI, and now I'm trying to do a sample main program with a PDF
containing some images.
This is my code, but I can't have any image stored and the methods of
DocumentExtractor are never called using debugger.
Thanks
Andrea
RecursiveParserWrapper parser = new RecursiveParserWrapper(
new AutoDetectParser(),
new BasicContentHandlerFactory(HANDLER_TYPE.XML, -1)
);
Metadata metadata = new Metadata();
ParseContext context = new ParseContext();
FileEmbeddedDocumentExtractor extractor = new
FileEmbeddedDocumentExtractor();
context.set(FileEmbeddedDocumentExtractor.class, extractor);
PDFParserConfig config = new PDFParserConfig();
config.setExtractInlineImages(true);
config.setExtractUniqueInlineImagesOnly(true);
context.set(org.apache.tika.parser.pdf.PDFParserConfig.class, config);
context.set(org.apache.tika.parser.Parser.class, new AutoDetectParser());
InputStream is = PdfRecursiveExample.class.getResourceAsStream("/my.PDF");
ToXMLContentHandler handler = new ToXMLContentHandler(new
FileOutputStream(new File("out.txt")), "UTF-8");
parser.parse(is, handler, metadata, context);
