[Bug 13156] New: ETO_OPAQUE and clear style are not transparent on a bitmap

http://bugs.winehq.org/show_bug.cgi?id=13156

Summary: ETO_OPAQUE and clear style are not transparent on a
                    bitmap
           Product: Wine
           Version: 1.0-rc1
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I paint some text on a bitmap using

Canvas.TextFlags:=ETO_OPAQUE;
  Canvas.Brush.Style:=bsClear;
  TextOut(...

resulting in a black background around the intended transparent text.

Can you attach a test program? (preferably with source)

Created an attachment (id=12998)
 --> (http://bugs.winehq.org/attachment.cgi?id=12998)
simple test program

procedure TForm1.Button1Click(Sender: TObject);
var bmp:TBitmap;
begin
  bmp:=TBitmap.Create;
  with bmp do
  try
    Width:=75;
    Height:=100;
    with Canvas do
    begin
      //background
      Brush.Style:=bsSolid;
      Brush.Color:=clYellow;
      FillRect(ClientRect);
      //foreground
      TextFlags:=ETO_OPAQUE;
      {ETO_OPAQUE       The text is drawn with an opaque background color.
      Using this flag improves performance but does not allow images
      behind the text rectangle to show.}
      Brush.Style:=bsClear;
      Font.Color:=clBlack;
      Font.Size:=72;
      TextOut(1,1,'A');
    end;
    Form1.Canvas.Draw(10,10,bmp);
  finally
    Free;
  end;
end;

Sourcecode is extensive and written in Delphi. I wrote some test code but
cannnot test it under Linux.

Is this still an issue in current (1.1.8 or newer) wine?

It is still an issue with release 1.1.8. Just have a look on my simple test
program.

It looks like I have the same problem but instead I call the Windows API
directly instead of using the Delphi wrappers. For me the following two
operations create inconsistent results on Windows and Wine:

* SetBkMode(DeviceContext, TRANSPARENT);
* ExtTextOut(DeviceContext, X, Y, ETO_OPAQUE, nil, Text, Length(Text), nil);

On Windows text is rendered with a transparent background and on Wine text is
rendered using an opaque background. It seems like in Windows SetBkMode 
overrides the ETO_OPAQUE parameter and on Wine it is the other way around.

I can confirm this issue in git (wine-1.3.29-121-gfdda702).
