Using GdViewer, since updating to v7.1, when I open a particular image from a stream and attempt to print it -- it prints a completely blank page (there definitely being data in the stream that was passed to the GdViewer.
If I attempt to open the same data from a file and print it, it prints perfectly. If possible, however, I'd like to avoid writing this data to disk.
Code: Select all
FirmCover fc = FirmCover.OpenReferenceNumber(coverId);
PdfDocument doc = new PdfDocument(); //Create a new document.
PdfSection section = doc.Sections.Add();
PdfPage page = section.Pages.Add();
page = Barcode.GenerateCoverPage(page, fc);
doc.Save(@_sTempPath + @"\Cover" + fc.ReferenceId.ToString() + ".pdf"); // saves to disk
MemoryStream ms = new MemoryStream();
//doc.Save(ms); // saving image to a memorystream did not work correctly in 7.1
GdPicture.GdViewer GdViewer1 = new GdPicture.GdViewer();
GdViewer1.SetLicenseNumber("xxx");
GdViewer1.DisplayFromFile(@_sTempPath + @"\Cover" + fc.ReferenceId.ToString() + ".pdf"); // load from file since memorystream load isnt working
//GdViewer1.DisplayFromStream(ms); // old statement for loading from memorystream
//GdViewer1.DisplayFirstPage();
GdViewer1.Print();
GdViewer1.CloseDocument();
File.Delete(@_sTempPath + @"\Cover" + fc.ReferenceId.ToString() + ".pdf");
