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.
