is it possible to leave the label and text in 90 degrees?

I succeeded as follows. Add text in an image equal to the idea of @ Junior

with the code below.

procedure TForm2.ConvTextOut(CV: TCanvas; const sText: String; x, y,
  angle: integer);
var
  LogFont: TLogFont;
  SaveFont: TFont;
begin
  SaveFont := TFont.Create;
  SaveFont.Assign(CV.Font);
  GetObject(SaveFont.Handle, sizeof(TLogFont), @LogFont);
  with LogFont do
  begin
    lfEscapement := angle *10;
    lfPitchAndFamily := FIXED_PITCH or FF_DONTCARE;
  end;
  CV.Font.Handle := CreateFontIndirect(LogFont);
  SetBkMode(CV.Handle, TRANSPARENT);
  CV.TextOut(x, y, sText);
  CV.Font.Assign(SaveFont);
  SaveFont.Free;
end;

ConvTextOut(Origem.Canvas, label1.caption, 0, 0, 0);
  Resultado.Width := Origem.Height;
  Resultado.Height := Origem.Width;
  Resultado.Update;
  for k := 0 to Origem.Width do
    for Y := 0 to Origem.Height do
      Resultado.Canvas.Pixels[Origem.Height-Y, k] := Origem.Canvas.Pixels[k,Y];

One thing that was not 100% in my opinion, was that the caption size inside the image was not a legal size.

You can not rotate the TLabel component (so far as I discovered), you can find components that support this behavior, FireMonkey is able to generate this effect!

However, follow a procedure that can clear your ideas and maybe get where you want!

Implement this in OnPaint of the form!

var
  lf: TLogFont;
  tf: TFont;
begin
  with Form1.Canvas do
  begin
    Font.Name := 'Arial';
    Font.Size := 24;
    tf        := TFont.Create;
    try
      tf.Assign(Font);
      GetObject(tf.Handle, SizeOf(lf), @lf);
      lf.lfEscapement  := 320;
      lf.lfOrientation := 320;
      SetBkMode(Handle, TRANSPARENT);
      tf.Handle := CreateFontIndirect(lf);
      Font.Assign(tf);
    finally
      tf.Free;
    end;
    TextOut(10, Height div 2, 'Texto Rotacionado aqui!');
  end;

Take a look at FireMonkey , you can find something I can help even more!

If it does not resolve, you can copy String and generate an image in ( TImage ), rotate and position in TLabel .
