Tim Allison updated TIKA-3270: ------------------------------ Attachment: tiger-no-text.png > 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 > Priority: Major > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
