下面的例子把文本旋转45度：
procedure TForm1.Button1Click(Sender: TObject);
var
lf : TLogFont;
tf : TFont;
begin
with Form1.Canvas do begin
Font.Name := 'Arial';
Font.Size := 24;
tf := TFont.Create;
tf.Assign(Font);
GetObject(tf.Handle, sizeof(lf), @lf);
lf.lfEscapement := 450;
lf.lfOrientation := 450;
tf.Handle := CreateFontIndirect(lf);
Font.Assign(tf);
tf.Free;
TextOut(20, Height div 2, 'Rotated Text!');
end;
end;
