Vitalie Bureanu updated PDFBOX-1553:
------------------------------------
Description:
Hello,
Preamble: We are glad to use PDFBox and I personally grateful to all developers
who sustain this project. It is good work, guys!
We have one problem. For our application purposes we extract from pdf "char by
char" with rispective coordinates for each char. (see attached Parser)
After this we group chars into the words. We noticed that for some pdf
documents we have a strange "offset" for extracted rect coordinates. (see
screens)
The offset is seems to be incremental (not sure) - at left top corner of
document is near to real coordinates of character, but at right bottom corner
is near to 0.5 cm..
If I make selection in Adobe Reader - it seems all ok.
I attached two pdf files with offset to this post.
If you want to see the offset "in action" you can use our service to do it at
http://pdf2data.cloudforpeople.com/ (Please do not consider it as advertising)
Please can you test these files and tell me if it is a really bug?
How we can resolve it?
Thanks,
Vitalie
