[device dots per inch] for monitor

[N.Y.P.D.]

Ladis and Genttlemen, how to get [device dots per inch] for device, which is called monitor. (I am stupid, I need example).

[Kambiz]

The following function returns horizontal and vertical DPI of the screen as a point.

Code: Select all

function GetScreenDPI: TPoint;
var
  DC: HDC;
begin
  DC := GetDC(0);
  try
    Result.X := GetDeviceCaps(DC, LOGPIXELSX);
    Result.Y := GetDeviceCaps(DC, LOGPIXELSY);
  finally
    ReleaseDC(0, DC);
  end;
end;

By the way, needing an example has nothing to do with stupidity. All of us get things better when there is an example.
