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

Duh, thanks! It worked. Now I have to figure out which config option was
messing it up.

If you turn off all the configurations, does it work for you?

I'm having luck with 2.1.0's app. How are you calling Tika? What
configurations do you have? Is tesseract on your command line, etc?
java -jar tika-app-2.1.0.jar ~/Downloads/sample\ german\ image.pdf
INFO [main] 10:07:23,958 org.apache.tika.parser.ocr.TesseractOCRParser
Tesseract is installed and is being invoked. This can add greatly to processing
time. If you do not want tesseract to be applied to your files see:

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?
