Problem running OCR
Ok this is one of those situations where I must be doing something stupid, but I can't get Tika to properly process the attached file. It's an image based PDF. It's just not getting any text out of it. Even if I run with OCRStrategy = ONLY_OCR.
It's definitely getting to the call to doOCROnCurrentPage(AUTO)in AbstractPDF2XHTML, so it's not a matter of the character counts preventing the OCR.
Don't think it has anything to do with the fact that it is in German. Tried setting the language to DEU, but same results
What is going on?

I even broke out my Windows laptop, and the basic commandline w tika-app
works there, too...in 2.0.0 and 2.1.0.

RE: Problem running OCR
Posted by Peter Kronenberg <pe...@torch.ai>.
So the option that was throwing me off was extractInlineImages. Has something changes recently? My code hasn’t changed and I’m not sure how I wouldn’t have noticed this before.
If extractInlineImages=false, does that mean that OCR won’t work at all for the PDF? Even if it is a non-searching PDF where each page is a scanned image?
And I can’t figure out why it’s set to FALSE. In tika-config.xml, I have
<parser class="org.apache.tika.parser.pdf.PDFParser">
<params>
<param name="extractInlineImages" type="bool">true</param>
</params>
</parser>
In my code, I have
TikaConfig tikaConfig;
try (InputStream is = TikaOCRParser.class.getClassLoader().getResourceAsStream("tika-config.xml")) {
tikaConfig = new TikaConfig(is);
}
final PDFParserConfig pdfConfig = new PDFParserConfig();
final TesseractOCRConfig tessConfig = new TesseractOCRConfig();
final AutoDetectParser parser = new AutoDetectParser(tikaConfig);
final ParseContext parseContext = new ParseContext();
parseContext.set(AutoDetectParser.class, parser);
parseContext.set(PDFParserConfig.class, pdfConfig);
parseContext.set(TesseractOCRConfig.class, tessConfig);
I know I probably talked to you about this at the time, and thought I had it right. Is this correct that I’m passing the tikaConfig to the AutoDetectParser()?
When I print the value of isExtractInlineImages right after instnatiaton PDFPaserConfig, it comes up as FALSE. What is the Tika default for this
