LMD 2024 TLMDSpeedButton certain images are not displayed

SOT3215229272

If I assign certain images to the glyph via Objebtinspector or from an LMDBitmapList, the image remains empty.
It works with the old 2019 version.

I have now found a solution myself:

procedure TLMDGlyph.UpdateMaster;

var
  done: Boolean;
  BMP: TBitmap;// BS 17.07.2025
begin
  done := False;
  if Assigned(FOnGetBitmap) then
  begin
    FMaster.Assign(nil); // Clear for sure.
    FOnGetBitmap(Self, FMaster, done);
  end;
  if not done then
  begin
    if FGlyph.PixelFormat = pf32bit then // BS 17.07.2025
    begin
      BMP := TBitmap.Create(FGlyph.Width, FGlyph.Height);
      try
        Bmp.Canvas.Draw(0,0, FGlyph);
        FMaster.Assign(Bmp);
      finally
        Bmp.Free;
      end;
    end
    else
      FMaster.Assign(FGlyph);
    FMaster.AlphaFormat := afDefined;
  end;
end;

Your bitmap is a 32bit bitmap with alpha-channel. Bitmap's alpha-channel contains only zeros, so it's fully transparent. As a result, it correctly shows as fully transparent (invisible).

I've converted it to 24bit bitmap without alpha-channel for you using free PixelFormer image editor.
