You can get a Hardcopy using Method GetFormImage from TForm.

Description

This example uses an image, a button, and a shape component on a form. When you click the button, an image of the form is stored in the FormImage variable and copied to the Clipboard. The image of the form is then copied back to the image component, producing an interesting result, especially if the button is clicked multiple times. Add ExtCtrls, StdCtrls, and Clipbrd to the uses clause.

Delphi-Quellcode:

procedure HardCopy(sJpegFile : String; fm : TForm);
Var
          FStream   : TStream;
          FBmp      : TPicture;
          FJpeg     : TJpegImage;
begin
  if SysUtils.FileExists(sJpegFile) then SysUtils.DeleteFile(sJpegFile);
  FStream := TFileStream.Create(sJpegFile,fmCreate);
  fm.WindowState := wsNormal;
  fm.Show;
  fm.Refresh;
  FJpeg := TJpegImage.Create;
  FBmp  := TPicture.Create;
  try
    FBmp.Bitmap.Assign(fm.GetFormImage); // <- get a Hardcopy from TForm
    FJpeg.Assign(FBmp.Bitmap);
    FJpeg.SaveToStream(FStream);
  finally
    FStream.Free;
    FJpeg.Free;
    FBmp.Free;
  end;
end;

end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ScreenShot(Image1.Picture.Bitmap; Form1); // <-- or any other TForm
