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.
