> Render non-text in PDFs for OCR
> -------------------------------
>
> Key: TIKA-3270
> URL: https://issues.apache.org/jira/browse/TIKA-3270
> Project: Tika
> Issue Type: Improvement
> Reporter: Tim Allison
> Assignee: Tim Allison
> Priority: Major
> Fix For: 2.0.0
>
> Attachments: test-no-text.png, test.png, tiger-no-text.png, tiger.pdf
>
>
> When we render a PDF page for OCR, we are relying on PDFBox to render all of
> the contents of the page, including text that may be available via regular
> extraction methods.
> The result of this is that if a user selects ocr_and_text, there can be
> duplicate text -- text as stored in PDFs and the text generated via OCR. In
> the xhtml output, we do mark a separate "div" for OCR so that users can
> distinguish, but still, it might be useful not to have to run OCR on text
> that was reliably extracted.
> One solution to this was proposed by [~lfcnassif] on TIKA-3258, with a
> technical/implementation recommendation by [~tilman] to subclass PDFRenderer
> and PageDrawer to render only the image components of a page.
> This would be a new, non-breaking feature. This is not a blocker on 2.0.0.
