.TesseractOCRParser does not extract text although Tesseract does

[David Pilato]

Hey team


I'm wondering what's wrong with my config.
I'm running this very basic piece of code:
@Test
public void testTika() throws TikaException, IOException, SAXException {
   BodyContentHandler handler = new BodyContentHandler(new 
WriteOutContentHandler(1000));
   new AutoDetectParser().parse(getBinaryContent("test-ocr.png"), handler, new 
Metadata(), new ParseContext());
   System.out.println("handler = " + handler);
}

Here are my logs:

16:31:13,089 DEBUG [o.a.t.p.o.TesseractOCRParser] hasTesseract (path: 
[tesseract]): true
16:31:13,560 DEBUG [o.a.t.p.o.TesseractOCRParser] hasTesseract (path: 
[tesseract]): true
16:31:13,564 DEBUG [o.a.t.p.o.TesseractOCRParser] ImageMagick does not appear

to be installed (commandline: convert)
handler =


The content is not extracted although Tesseract is detected.

When I run Tesseract manually:

tesseract test-ocr.png tess.out
cat tess.out.txt

I'm getting:

This file contains some words.

tesseract --version gives

What I'm missing here?
