Posted - Dec 25 2025 : 18:28:01 When I use TImageEnMView for duplex scanning, how can I determine whether the currently acquired image is the front or back side of the scan?

At this time, it is only supported by tracking the image sequence:
procedure TForm1.ImageEnMView1AcquireBitmap(Sender: TObject; ABitmap: TIEBitmap; DpiX, DpiY: Integer; var Handled: boolean);
var
isFrontSide: Boolean;
begin
Inc( fImagesAcquired );
// Odd images = Front, Even images = Back
isFrontSide := (fImagesAcquired mod 2) = 1;
...
end;
