make_trans_font(3)		 Allegro manual 	      make_trans_font(3)

NAME
     make_trans_font  -  Makes a font use transparency. Allegro game programming
     library.

SYNOPSIS
     #include <allegro.h>

     void make_trans_font(FONT *f);

DESCRIPTION
     This function converts a font to use transparency	for  drawing.  That  is,
     each glyph in the font will be drawn with draw_trans_sprite, so you can use
     the  same	blenders  as with draw_trans_sprite to draw the font. One common
     use of this is to load a bitmap font with an alpha channel,  and  therefore
     get  anti-aliased	text  output by using Allegro's alpha blender. Here's an
     example how to do that:

	FONT *f = load_font("alphafont.tga", NULL, NULL);
	make_trans_font(f);
	set_alpha_blender();
	textprintf_centre_ex(screen, f, 320, 240, -1, -1, "Anti-aliased Font!");

SEE ALSO
