.net - Print XpsDocument scaled to fit page -


we using telerik's wpf charting controls in our application. charting controls have built-in support exporting graphics xps file. want utilize wpf's support printing xps documents print chart. part, works great, i'm having trouble scaling chart fit 1 page. chart graphic cut off on right , bottom. chart coming out large page. ideas?

here code i'm using:

const string packageuristring = "pack://inmemorychart.xps";  using (var memorystream = new memorystream()) {     //utilize telerik chartview method export xps...      _chart.exporttoxps(memorystream);      using (var package = package.open(memorystream))     {         var packageuri = new uri(packageuristring);          packagestore.addpackage(packageuri, package);          var xpsdocument = new xpsdocument(package, compressionoption.maximum, packageuristring);          var printdialog = new printdialog();         var result = printdialog.showdialog();          if (!result.getvalueordefault())             return;          var fixeddocumentsequence = xpsdocument.getfixeddocumentsequence();          if (fixeddocumentsequence == null)             return;          var documentpaginator = fixeddocumentsequence.documentpaginator;          if (documentpaginator == null)             return;          //attempt adjust fit page?         adjustflowdocumenttopage(documentpaginator, printdialog.printqueue);           printdialog.printdocument(documentpaginator , "chart");          packagestore.removepackage(packageuri);     } }

i found adjustflowdocumenttopage on site:

public static void adjustflowdocumenttopage(documentpaginator documentpaginator, printqueue printqueue) {    const double inch = 96;     var printticket = printqueue.userprintticket;     // media size.    double width = printticket.pagemediasize.width.value;    double height = printticket.pagemediasize.height.value;     // set margins.    const double leftmargin = 1.25 * inch;    const double rightmargin = 1.25 * inch;    const double topmargin = 1 * inch;    const double bottommargin = 1 * inch;     // calculate content size.    var contentwidth = width - leftmargin - rightmargin;    var contentheight = height - topmargin - bottommargin;     documentpaginator.pagesize = new size(contentwidth, contentheight); }

upon further research, found following implementation , seems work great! http://www.telerik.com/community/forums/wpf/chart/behaviour-based-chart-print-solution.aspx
