    BOOST_STATIC_ASSERT((num_channels<rgb8_view_t>::value==3));
    BOOST_STATIC_ASSERT((num_channels<cmyk16_planar_ptr_t>::value==4));

    BOOST_STATIC_ASSERT((is_planar<rgb16_planar_image_t>::value));
    BOOST_STATIC_ASSERT((is_same<color_space_type<rgb8_planar_ref_t>::type, rgb_t>::value));
    BOOST_STATIC_ASSERT((is_same<channel_mapping_type<cmyk8_pixel_t>::type,
                                 channel_mapping_type<rgba8_pixel_t>::type>::value));
    BOOST_STATIC_ASSERT((is_same<channel_type<bgr8_pixel_t>::type, bits8>::value));
