Subject [jira] [Commented] (PDFBOX-4367) Error expected floating point number actual='18-5'
Date Wed, 07 Nov 2018 17:40:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16678555#comment-16678555

Peter Johnson commented on PDFBOX-4367:

We are using Tika programmatically.  However, I could not figure out how to have it only
parse one page at a time.  There is a way to override the ContentHandler to receive one page
at a time after it is parsed, but by then it is too late.


If you do make the change to allow us to skip bad content (by page or any other means of dividing
text), that would be greatly appreciated.  We would then try to get that option exposed in
Tika.  Thanks for the responses!

>             Project: PDFBox
>          Issue Type: Bug
>          Components: Text extraction
>    Affects Versions: 2.0.12
>         Environment: Mac OS X Sierra
>            Reporter: Peter Johnson
>            Priority: Minor
> Able to repeat with command line.  Unfortunately, the only files that repeat this are
from a customer, and contain sensitive information.  The file opens without error in Acrobat
Reader and Mac Preview.  The desired result is that any corrupt portions of the PDF are skipped,
so that we can use what text is extractable.
> Unfortunately, I still get an error when using the -force option.
