[jira] [Closed] (PDFBOX-1331) Can't load any text when font is null

Posted by "Timo Boehme (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/PDFBOX-1331?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Timo Boehme closed PDFBOX-1331.
-------------------------------

       Resolution: Not A Problem
    Fix Version/s: 1.7.0
         Assignee: Timo Boehme

The document is broken. Values of length parameter in streams are wrong (too large by some bytes e.g. in object 249). Even a fall back to the sequential parser seems not possible with this document.

[jira] [Resolved] (PDFBOX-1331) Can't load any text when font is null

Posted by "Timo Boehme (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/PDFBOX-1331?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Timo Boehme resolved PDFBOX-1331.
---------------------------------

       Resolution: Duplicate
    Fix Version/s:     (was: 1.7.0)
                   1.8.0

Ok, this issue has more interesting aspects as I though first (thanks for insisting on it).

First it is true that the document is broken. Some readers will hide error messages to the user, but xpdf for instance will show them (you can test it yourself e.g. with object 249 where the length is some bytes too large). Since NonSeqPDFParser currently does not try to repair such documents it will fail.

For the standard parser 1.7.0 introduced an improvement when parsing streams by using length value. Now if this value is wrong it fails too. The solution would be to fall back to old (scanning) stream parsing in such cases. I have created a dedicated issue for this improvement with PDFBOX-1333.

There is another (independent) isssue with PDFStreamEngine.getFonts if no fonts are defined. I will track this in a new issue.

resolved as duplicate of PDFBOX-1333; using this patch allows parsing document with standard parser

philip huang reopened PDFBOX-1331:
----------------------------------


I don't think this document is a wrong document. Adobe reader and Foxit reader can also show it correctly.
I think the document is generated by non-standard creator , it maybe include some new PDF features.
