Subject [jira] [Commented] (TIKA-2174) JP2 and JPX (JPEG 2000) support not declared by TesseractOCRParser
Date Wed, 09 Nov 2016 12:56:59 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15650860#comment-15650860

Tim Allison commented on TIKA-2174:
-----------------------------------

Thank you for opening this. Will fix. To confirm, you're running ocr on extracted inline images?
 We added a new way to handle ocr of PDFs that uses pdfbox to generate a single image of each
page and then runs ocr on that.  I suspect that one strategy will be better for some PDFs
and the other for others. Will document on our wiki shortly.

>             Project: Tika
>          Issue Type: Bug
>          Components: parser
>    Affects Versions: 1.14

> Tesseract produces OCR output fine for JPX images as of this version:
> {noformat}
>   $ tesseract -v
>      tesseract 3.04.01
>        leptonica-1.73
>          libjpeg 8d : libpng 1.6.26 : libtiff 4.0.6 : zlib 1.2.5}}
> {noformat}
> However, these types are not declared by getSupportTypes so no output is produced for
PDFs which contained JPX images of scanned documents, for example.
