["Andreas Lehmkühler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12661242#action_12661242 ] 

Andreas Lehmkühler commented on PDFBOX-358:
-------------------------------------------

Version 732038 contains a patch to solve some displaying issues if the rotation-angle is not a multiple of 90 degrees.
I'll try the stripping-part later.

> Vertical text gets splitted during extraction using PDFTextStripper.
> "Specification" gives:
> Spécif
> ic
> ations
> This is made worse when sorted by position, as it gets mixed up with the
> horizontal text:
> ic
> ations
> [CLASSIFIED INFO]
> [CLASSIFIED INFO]
> Spécif [CLASSIFIED INFO]
> [CLASSIFIED INFO]
> I'm afraid I can't provide the PDF in question due to confidentiality
> requirements. It's a PDF obtained from the conversion to PDF of a Windows
> Word document. According to the forums I'm not the only one with this
> problem.

> I have attached an admittedly very complicated PDF document which (as far
> as I can tell) features 90° and 135° rotated text in a 90° rotated page.
> Position-ordered text extraction gives horrible results. 
> Normal text extraction is also very messy, although in this second case
> the results are almost understandable. 
> This is not the document I need to treat, but i think that if text can be
> correctly extracted from that PDF, it should work for almost every other
> existing PDF.
