PrintHDC outputs a blank page

1. offizieller Beitrag

    Hi

    I am using V1.46 of WPViewPDF and am trying to use the PrintHDC method to output a pdf to the printer canvas as shown below but I always get a blank page being output

    Printer.BeginDoc;
    WPViewPDF1.PrintHDC(1, Printer.Canvas.Handle, 600, 600);
    Printer.EndDoc;

    However the PrintPages method as shown below works fine.

    WPViewPDF1.BeginPrint('Microsoft Office Document Image Writer');
    WPViewPDF1.PrintPages(0, 0);
    WPViewPDF1.EndPrint;

    I need to use the PrintHDC as I want the contents of a pdf file to be output in the current print job, not a new print job.

    Any ideas?

    Regards

    PrintHDC(0,..) doesn't output anything either. What do you do internally that is different between the PrintHDC command and the PrintPages command. Does PrintPages use the same code as PrintHDC ?

    Hi

    I have gotten around this problem by using the GetMetaFilePrn method and then doing PlayEnhMetaFile(Printer.Canvas.Handle, MetaFile.Handle, Rect(0,0,Printer.PageWidth,Printer.PageHeight))
