NAME

6       make_trans_font  - Makes a font use transparency. Allegro game program‐
7       ming library.

SYNOPSIS

10       #include <allegro.h>
11
12
13       void make_trans_font(FONT *f);
14

DESCRIPTION

16       This function converts a font to use transparency for drawing. That is,
17       each glyph in the font will be drawn with draw_trans_sprite, so you can
18       use the same blenders as with draw_trans_sprite to draw the  font.  One
19       common  use of this is to load a bitmap font with an alpha channel, and
20       therefore  get  anti-aliased  text  output  by  using  Allegro's  alpha
21       blender. Here's an example how to do that:
22
23
24          FONT *f = load_font("alphafont.tga", NULL, NULL);
25          make_trans_font(f);
26          set_alpha_blender();
27          textprintf_centre_ex(screen, f, 320, 240, -1, -1, "Anti-aliased Font!");
