text rotation

I am printing caracters with GlBitmap in screen coord ( with glOrtho2D), and I would like to make them rotate.
I have tried a simple glRotate, but it seems that it is not applied to bitmap characters (it works with lines).

Is there a solution for me to do that?
Thanks in advance

You will have to load the text bitmaps to a texture and draw a textured quad to the screen.

There are libraries that can help you do this.
