[jira] [Commented] (PDFBOX-4101) Word ordering / line detection
failures in text extraction
[ https://issues.apache.org/jira/browse/PDFBOX-4101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16354597#comment-16354597 ]
Tilman Hausherr commented on PDFBOX-4101:
-----------------------------------------
Try the sort option... however you still won't be satisfied... PDFBox doesn't know about columns. You as a human know this, but PDFBox doesn't have any heuristics to detect this. It can be done with "article beads" but your PDF doesn't have them. Same for the "D" - how would PDFBox "know" that it belongs to the very beginning?

> Dear Apache contributors,
> I am a (y) user of pdfbox mainly for the purpose of text extraction. The word ordering is not correct for some cases and the line detection may fail too.
> Attachments:
> * 1st page: the first letter D is not written before "uis sit amet..." but at the end of the page ;
> * 2nd page: the sentence "scolaire ferry" is just before "réouverture du musée" which is wrong because it's not on the same column ;
> To manage these cases would be more than welcome :D A.
