NAME

       makeacol,  makeacol_depth  -  Converts  RGBA  colors into display dependent pixel formats.
       Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

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

       int makeacol_depth(int color_depth, int r, int g, int b, int a);

DESCRIPTION

       Convert RGBA colors into display dependent pixel formats. In anything less than  a  32-bit
       mode,  these  are  the  same  as  calling makecol() or makecol_depth(), but by using these
       routines it is possible to create 32-bit color values that contain  a  true  8  bit  alpha
       channel  along  with  the red, green, and blue components. 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.

RETURN VALUE

       Returns the requested RGBA quadruplet.
