[jira] [Commented] (TIKA-2584) Tika should have a way to pass
arbitrary Tesseract options
[ https://issues.apache.org/jira/browse/TIKA-2584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16372078#comment-16372078 ]

--------------------------------------
ewanmellor opened a new pull request #224: Fix for TIKA-2584 contributed by ewanmellor.
URL: https://github.com/apache/tika/pull/224
Add TesseractOCRConfig.{add,get}OtherTesseractConfig, plus parsing of
TesseractOCRConfig.properties to extract any key-value pair where the key
has an underscore.
Inside TesseractOCRParser, pass these key-value pairs to Tesseract using
its -c command line option.
This gives a mechanism by which user code can pass arbitrary options to
Tesseract without Tika having to understand them.
This PR depends on PR 222 / TIKA-2582 because of merge conflicts.

> Key: TIKA-2584
> URL: https://issues.apache.org/jira/browse/TIKA-2584
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Affects Versions: 1.17
> Reporter: Ewan Mellor
> Priority: Minor
>
> Tesseract has a very large number of config options (use tesseract --print-parameters to see them). There is no mechanism for TesseractOCRParser / TesseractOCRConfig to pass these to Tesseract, and so they cannot be controlled by user code.
> Tika should pass these through as opaque key-value pairs, so that user code can set them as necessary.
