makeacol32(3)			Allegro	manual			 makeacol32(3)

NAME
       makeacol32 - Converts an	RGBA color into	a 32-bit display pixel format.
       Allegro game programming	library.

SYNOPSIS
       #include	<allegro.h>

       int makeacol32(int r, int g, int	b, int a);

DESCRIPTION
       Converts	an RGBA	color into a 32-bit display pixel  format,  which  in-
       cludes  an  alpha  (transparency)  value. There are no versions of this
       routine for other color depths, because	only  the  32-bit  format  has
       enough  room  to	store a	proper alpha channel. You should only use RGBA
       format	colors	 as    the    input    to    draw_trans_sprite()    or
       draw_trans_rle_sprite()	after calling set_alpha_blender(), rather than
       drawing them directly to	the screen.
