             Summary: OpenText - Exstream PDFs textual informations are recognized with erroneous font size
                 Key: PDFBOX-3841
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3841
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 1.8.13, 1.8.12
         Environment: Windows/Linux
            Reporter: Maxime Veron
         Attachments: 436bc378-aa42-43e5-a4de-a0bbaf233f79-4.PDF vII.PDF

I'm creating this bug report because I observed a particular behavior in PDFBox parsing of text positions. 

I used the command line tool (PrintTextPositions) to generate the text positions and remove any code logic our application could have over PDFBox and here is an extract of the result : 

String[17.279999,18.800049 fs=*50.0 *xscale=12.0 height=6.918 space=3.0 width=3.9960938]-
String[21.6,18.800049 fs=*50.0 *xscale=12.0 height=6.918 space=3.0 width=5.999998]*
String[28.08,18.800049 fs=*50.0 *xscale=12.0 height=6.918 space=3.0 width=3.9960918]-
String[31.679998,18.800049 fs=*50.0 *xscale=12.0 height=6.918 space=3.0 width=3.000002]

The font size is reported as 50.0 (which is indeed contained in the PDF as 50) but Adobe and other PDF viewers do not seem to take into account this font of size 50 to render the text selection. Should we rely on another metric from the text position, or could this font size be reported relative to the correct appearance the text should have?

Best regards
