how can I create a bitmap from a rich edit box

I need to be able to create a bitmap from a rich edit box so I can avoid having to have my customers fonts on my machine so I can print their labels. I have tried copyrect but this requires a canvas on the control. My best bet seems to be paintto but I have had trouble grappling with device contexts.

My code to date is following. Hope someone out there can help.
var
bitmap:TBitmap;
dev:HDC;
begin
bitmap:=TBitmap.create;
try
dev:=bitmap.canvas.handle;
bitmap.height:=beamfrom.ClientHeight;
bitmap.width:=beamfrom.ClientWidth;
bitmap.pixelformat:=pfdevice;

beamfrom.paintto(dev,0,0);
beamto.Picture.Assign(bitmap);
finally
bitmap.free;
end;
end;

Hi!

Try this code, which uses the form's canvas to copy the rich edit into a TImage and then to disk (written in D3):

procedure TForm1.Button1Click(Sender: TObject);
var
  Dest,
  Source : TRect;

begin
  Source.Top := richedit1.Top;
  Source.Left := richedit1.Left;
  Source.Bottom := (richedit1.Top + richedit1.Height);
  Source.Right := (richedit1.Left + richedit1.Width);
  Dest.Left := 0;
  Dest.Top := 0;
  Dest.Bottom := richedit1.Height;
  Dest.Right := richedit1.Width;
  image1.Height := richedit1.Height;
  image1.Width := richedit1.Width;
  image1.Canvas.CopyRect(Dest,form1.canvas,Source);
  image1.Picture.SaveToFile('Test.BMP');
end;

You could make the image invisible, it should work anyway...
