Printing and Exporting
- 2 minutes to read
To invoke the standard Print dialog, select Print in the application menu. The Print dialog allows you to select the printer (if required), specify the range of pages to print, the number of copies, etc. To invoke the dialog in code, use the DiagramControl.Print method.
The Quick Print application menu item immediately sends the diagram to the default printer. The corresponding method is DiagramControl.QuickPrint.
The Print Preview application menu item invokes the Print Preview dialog. The corresponding method is DiagramControl.ShowPrintPreview.
The Print Preview dialog allows you to select the printed page size. If you do not modify this setting, the drawing page size specified in the Page Setup Dialog Window is used.
To specify a custom background for printed pages, use the DiagramControl.PrintPageBackgroundTemplate property.
Export
To export a diagram to a file, select Export As in the application menu. This command invokes the Export As dialog where you can specify the output format and file path.
Diagrams can be exported to the following formats: GIF, PNG, BMP, JPG, PDF, SVG.
The following export settings are available:
- DiagramControl.ExportDPI - the resolution (in dpi).

You can override these settings in the parameters of the export methods.
Use the DiagramControl.ExportDiagram method to invoke the Export As dialog window. This window allows users to select any available file format.
