[Sergey Beryozkin]

Hi Tim

and when is "extractInlineImages" actually effective ?

Thanks, Sergey

Y, well, sorry.  I’m thrilled someone is using it!

I tried to document that here:

https://wiki.apache.org/tika/PDFParser%20%28Apache%20PDFBox%29

See the OCR section.

And there’s a link to that page from https://wiki.apache.org/tika/TikaOCR (See OCR on PDFs)

How can we improve the documentation so that you don’t waste an hour?

Got it working. In case someone else hits the same issue, here is my config file... Well... That was obvious :D

/<?/*xml version**="1.0" **encoding**="UTF-8"*/?>
/<*properties*>
<*parsers*>
<*parser class="org.apache.tika.parser.DefaultParser"*/>
<*parser class="org.apache.tika.parser.pdf.PDFParser"*>
<*params*>
<*param name="ocrStrategy" type="string"*>ocr_and_text</*param*>
</*params*>
</*parser*>
</*parsers*>
</*properties*>

    So I saw in debug mode that indeed config.getExtractInlineImages()
    is false so I'm going to check my config.

    :D

        Hey guys

        First post here ;)

        I'm trying to play with OCR with Tika. I installed Tesseract and
        I can extract text from a PNG image.

        I created a PDF document with this image embedded and I'm trying
        now to extract the text out of it.

        I added this configuration but I guess I'm doing it wrong:

        /<?/*xml version**="1.0" **encoding**="UTF-8"*/?>
        /<*properties*>
        <*parsers*>
        <*parser class="org.apache.tika.parser.DefaultParser"*>
        </*parser*>
        <*parser class="org.apache.tika.parser.pdf.PDFParser"*>
        <*params*>
        <*param name="extractInlineImages" type="bool"*>true</*param*>
        </*params*>
        </*parser*>
        </*parsers*>
        </*properties*>

        I'm creating my Tika instance with something like:

        TikaConfig config = *new
        
*TikaConfig(TikaInstance.*class*.getResourceAsStream(*"/tika-config.xml"*));
        detector = config.getDetector();
        parser = *new *AutoDetectParser(config);

        /tika /= *new *Tika(detector, parser);

        Any idea? I'm feeling that my xml config is wrong but can't find
        what should be the right syntax.

        Thanks for your help guys!
        David
