PDFParser mixes the text from separate columns
----------------------------------------------
Key: TIKA-611
URL: https://issues.apache.org/jira/browse/TIKA-611
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 0.9
Reporter: Julien Nioche
Assignee: Julien Nioche
Fix For: 1.0
As reported on the dev list by Michael Schmitz :
bq. I don't think the current snapshot is parsing articles (pdfs with
columns/beads) correctly. The text is not in the write order as it intermixes
text from different beads. Try it on an academic paper.

This can be fixed by changing the value of setSortByPosition to false, which is
the default value in PDFTextStripper. This line (PDF2XHTML:82) had been added
as part of the commit rev 1029510, see
https://issues.apache.org/jira/browse/TIKA-446?focusedCommentId=12926787&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12926787
Ideally we could specify what value to set for these parameters via the Context
object, but for the time being wouldn't it make sense to set setSortByPosition
to the default value of false? I think that this would be the best option for
most cases where docs have columns.
