I think this nailed it. The code should append 05 but of course only appends 5. Meanwhile the code has been simplified to only support 1 decimal according to: <a href="http://opengrok.libreoffice.org/">http://opengrok.libreoffice.org/</a> It's a pity because this prevents LO to export fine detailed Vector-PDFS. I attached a testfile.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
