Subject [jira] [Commented] (PDFBOX-4367) Error expected floating point number actual='18-5'
Date Tue, 06 Nov 2018 04:19:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16676114#comment-16676114

Tilman Hausherr commented on PDFBOX-4367:
-----------------------------------------

The "-force" option is a documentation mistake, there's a fresh issue about it, PDFBOX-4369.

There is no option to process each page by itself. Apache Tika (which uses PDFBox) has it,
I know it because we discussed it maybe a year ago. I can't find it on [https://tika.apache.org/1.19.1/gettingstarted.html]
so maybe it isn't available on the command line, only programmatically.

You could also modify ExtractText for yourself. You first get the number of pages (document.getNumberOfPages()),
and then call `setStartPage()` and `setEndPage()` for each page and run `writeText()` several
times.

I could also implement it for ExtractText, it would make sense for people who need this and
can't change the code. Main problem is that I'd need a good name for the option. (Not "force").

> 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.
> We get the following stack trace:
