Hello,

I need to rotate the text by 90, 180, 270 degrees.
Does anyone know how to do it by using standard windows API?


Thank you
Rony.

  //Apply rotation of n deg.

  //create a new font based upon new settings
  SelectObject (Canvas->Handle, HFnt);

  //sample text
  TextOut (Canvas->Handle, 100, 100, &Text[1], Text.Length());

  //free resources
  DeleteObject ( HFnt );
