> 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 coordinates. (see screens)
> The offset is incremental - at left top corner of document is near to real coordinates of charcater, 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)
