Hi guys,

I want to try to rotate some text. To do this it might be best to put the text into a bitmap, and rotate that. But I have no idea how I could get text into a bitmap.

Any ideas?

With A5, this is pretty easy to do:

al_set_target_bitmap(text_bitmap);
//draw the text
al_set_target_bitmap(al_get_backbuffer(al_get_current_display())); //reset the target bitmap

Transformations will work fine too:

#SelectExpand
  1ALLEGRO_TRANSFORM old, new;
  2
  3/* Save the current transform */
  4al_get_current_transform(&old);
  5
  6/* Create the new transform and use it */
  7al_identity_transform(&new);
  8al_translate_transform(&new, -cx, -cy);
  9al_rotate_transform(&new, angle);
 10al_translate_transform(&new, dx, dy);
 11al_use_transform(&new);
 12
 13/* Draw text at 0,0 as the transformation takes care of the positioning */
 14al_draw_text(font, color, 0, 0, 0, "blah");
 15
 16/* Reset the old transformation*/
 17al_use_transform(&old);
