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
       includes 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.
