Example 





GdPicture14.WPF Namespace > GdViewer Class > PrintDialog Method : PrintDialog(PrintSizeOption) Method
A member of the PrintSizeOption enumeration. Sets up the automatic scalling of a printed document to fit the current paper size.
Invokes the standard Windows Print dialog box, which allows you to select additional options or settings and then to print the document currently displayed in the GdViewer control. You can also adjust the size of printed pages according to your preference using this method for printing.

During the print process, the BeforePrintPage and the AfterPrintPage events are raised just before and right after the single page is printed.

Parameters

PrintSizeMode
A member of the PrintSizeOption enumeration. Sets up the automatic scalling of a printed document to fit the current paper size.

Return Value

true if the method has been followed successfully, otherwise false. Please use the PrintGetStat method to determine the reason for the printing failure.
Remarks
We strongly recommend using the GetStat method or the PrintGetStat method to identify the specific reason for the method's failure.

Just to remind you that you can also utilize both the BeforePrintPage and the AfterPrintPage events during the print process using this method.

You also need to be aware that annotations and form fields included in the document are rendered by default using this method when printing.
