NAME

       getr,  getg, getb, geta - Extract a color component from the current pixel format. Allegro
       game programming library.

SYNOPSIS

       #include <allegro.h>

       int getr(int c);

       int getg(int c);

       int getb(int c);

       int geta(int c);

DESCRIPTION

       Given a color in the format being used by the current video mode, these functions  extract
       one of the red, green, blue, or alpha components (ranging 0-255), calling the preceding 8,
       15, 16, 24, or 32-bit get functions as appropriate. The alpha part is only meaningful  for
       32-bit pixels. Example:

          int r, g, b, color_value;

          color_value = getpixel(screen, 100, 100);
          r = getr(color_value);
          g = getg(color_value);
          b = getb(color_value);
