Tim Allison commented on TIKA-2167:
-----------------------------------
Thank you for opening this. Can you give more info on what is failing? What
is the stacktrace? How are you running Tika (tika-app, tika-server, API)?
When I run this in trunk via the API:
{noformat}
@Test
public void testTiff() throws Exception {
XMLResult r = getXML("simple.tiff");
System.out.println(r.xml);
}
{noformat}
I get this:

Looks like we need to fix the xhtml (just opened TIKA-2169), but I'm not
getting a fail...
> Image processing causes OCR to fail
> -----------------------------------
>
> Key: TIKA-2167
> URL: https://issues.apache.org/jira/browse/TIKA-2167
> Project: Tika
> Issue Type: Bug
> Components: ocr
> Affects Versions: 1.14
> Environment: Mac OS X 10.11.6; Java 1.8.0_45; tesseract 3.04.01;
> ImageMagick 6.9.6-2
> Reporter: Matthew Caruana Galizia
> Priority: Critical
> Labels: convert, image, ocr, tiff
> Attachments: simple.tiff
>
>
> Image processing before OCR is enabled by default in the OCR configuration
> properties file. Unless this is disabled, running Tika on a simple TIFF image
> (attached) with two clear words fails. When image processing is disabled, it
> succeeds.
