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.
