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 rou-
       tine for other color depths, because only the 32-bit format has enough room to store a proper alpha channel. You should only use RGBA  for-
       mat  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.
