Printing existing pdf file with overlay in c# code

[slimke]

Hello guys,

my company is using a registered licence for pdf x-change 5 api.
now i want to use the api to set up a temporary printer which should open an existing pdf file, overlay it with another existing pdf file and save it to special path

my code atm looks like this:

Code: Select all

			
PXCComLib5.CPXCControlEx prnFactory = new PXCComLib5.CPXCControlEx();
_pdfPrinter = (PXCComLib5.CPXCPrinter)prnFactory.get_Printer("", "Simple PDF-XChange 2012", "<regCode>", "<devCode>");
			
_pdfPrinter.ResetDefaults();
_pdfPrinter.Option["Save.File"] = @"\\my\path\to\the\final\output\file.pdf";
_pdfPrinter.Option["Save.SaveType"] = 2;
_pdfPrinter.Option["Save.ShowSaveDialog"] = "no";
_pdfPrinter.Option["Saver.ShowProgress"] = "no";
_pdfPrinter.Option["Save.WhenExists"] = "Overwrite";
_pdfPrinter.Option["Save.RunApp"] = "Yes";
_pdfPrinter.Option["Overlay.Enabled"] = "Yes";
_pdfPrinter.Option["Overlay.OverlayFile"] = @"\\my\path\to\the\overlay\file.pdf";

im missing some parameter/property where i can set up the original pdf file (which should be overlayed) like

_pdfPrinter.Option["Open.File"] = @"\\my\path\to\the\file\that\should\be\overlayed.pdf";

Is there any way to realize this? If "yes"...how?!
Thank's for your support!

Hello slimke,

The printing drivers are designed to only create new files, and there is the Overlay option, but that can only be applied to newly "printed" files, so you will need to either "repritnt" the original document through the drivers, or use the PDF Tools SDK to do the overlay:
