Summary: OCR in PDF files
Key: TIKA-1729
URL: https://issues.apache.org/jira/browse/TIKA-1729
Project: Tika
Issue Type: Bug
Components: config, parser
Affects Versions: 1.10, 1.9
Environment: Windows 7, 64-bit, JDK 1.8.0_51 64 bit
Reporter: Loris Bachert
As described in this
[stackoverflow-post|http://stackoverflow.com/questions/32354209/apache-tika-extract-scanned-pdf-files]
i'm having troubles extracting text out of scanned PDF files. By scanned PDF
files i mean PDF files that consist only of images. Because each page is an
image i can't extract them using a custom ParsingEmbeddedDocumentExtractor. I
also tried using the setExtractInlineImages method of the PDFParserConfig but
this didn't work aswell.
There was already a [ticket|https://issues.apache.org/jira/browse/TIKA-93]
regarding the OCR support and including the [PDF
file|https://issues.apache.org/jira/secure/attachment/12627866/testOCR.pdf] i'm
using for my tests.
Here is a JUnit-test about my issue:
{code:title=PDFOCRTest.java|borderStyle=solid}
@Test
public void testPDFOCRExtraction() throws IOException, SAXException,
TikaException {
File file = new File(filePath);
InputStream stream = new FileInputStream(file);
BodyContentHandler handler = new BodyContentHandler(Integer.MAX_VALUE);
Metadata metadata = new Metadata();
PDFParserConfig config = new PDFParserConfig();
config.setExtractInlineImages(true);
ParseContext context = new ParseContext();
context.set(PDFParserConfig.class, config);
PDFParser pdfParser = new PDFParser();
pdfParser.setPDFParserConfig(config);
pdfParser.parse(stream, handler, metadata, context);
String text = handler.toString();
assertFalse(text.isEmpty());
}
{code}
