Image Device Fundamentals

The Image device descendents give the capability to easily export any report to various image formats which can be viewed using an image viewer or editor.

Begin by setting the Report.AllowPrintToFile property to True to enable the Print To File section of the Print Dialog. The print dialog can be bypassed by setting the Report.DeviceType property to the image type (ex. "BMP"), assigning the Report.TextFileName property, and setting the Report.ShowPrintDialog property to False.

uses
  ppTypes;

procedure TForm1.btnPrintClick(Sender: TObject);
begin
  ppReport1.AllowPrintToFile := True;
  ppReport1.ShowPrintDialog := False;
  ppReport1.DeviceType := dtBMP;

  ppReport1.TextFileName := 'C:\MyImageFile.bmp';

  ppReport1.Print;

end;
