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.
