[jira] [Created] (PDFBOX-1140) TTFDataStream.read32Fixed() discards fractions

TTFDataStream.read32Fixed() discards fractions
----------------------------------------------

                 Key: PDFBOX-1140
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1140
             Project: PDFBox
          Issue Type: Bug
          Components: FontBox
    Affects Versions: 1.6.0
            Reporter: Arjohn Kampman
            Priority: Minor
         Attachments: TTFDataStream.patch

TTFDataStream.read32Fixed() tries to calculate its fracional part by dividing an unsigned short with 65536. But because this method uses an integer division, the fractional value will always be 0. I've attached a simple patch that fixes this.
