Tyler Palsulich commented on TIKA-93:
-------------------------------------
Thanks for the help! I applied the patch. But, there are two copies of each
class in the patch. Is that intentional? I just deleted one of the copies. I
installed Tesseract and added the TesseractOCRParser to the META-INF file, but
OCR isn't running on the example PDF. Should I be using an AutoDetectParser? I
put my parse-only test below (I put testOCR.pdf in test-documents/ocr/ since it
was messing with PDFParserTest.)
{code}
@Test
public void testPDFOCR() throws Exception {
Parser parser = new AutoDetectParser();
BodyContentHandler handler = new BodyContentHandler();
Metadata metadata = new Metadata();
TesseractOCRConfig config = new TesseractOCRConfig(); // Have
Tesseract on my PATH.
ParseContext parseContext = new ParseContext();
parseContext.set(TesseractOCRConfig.class, config);
InputStream stream = TesseractOCRTest.class.getResourceAsStream(
"/test-documents/ocr/testOCR.pdf");
try {
parser.parse(stream, handler, metadata, parseContext);
} finally {
stream.close();
}
}
{code}
