SYNOPSIS#include <allegro.h> int getr_depth(int color_depth, int c); int getg_depth(int color_depth, int c); int getb_depth(int color_depth, int c); int geta_depth(int color_depth, int c);
DESCRIPTIONGiven a color in the format being used by the specified color depth, these functions extract one of the red, green, blue, or alpha components (ranging 0-255). The alpha part is only meaningful for 32-bit pixels. Example: int r, g, b, color_value, bpp; bpp = bitmap_color_depth(bitmap); color_value = getpixel(bitmap, 100, 100); r = getr_depth(bpp, color_value); g = getg_depth(bpp, color_value); b = getb_depth(bpp, color_value);
