Hi All,

 

The following code is straight out of the tutorial about making function generic. Can anyone suggest how I might determine the layout of DstView here so that I can build an image of the same layout? In this example they hardcode gray_layout_t and I’m not seeing any metafunctions that return the layout.

 

template <typename SrcView, typename DstView>

void x_luminosity_gradient(const SrcView& src, const DstView& dst) {

    typedef typename channel_type<DstView>::type d_channel_t;

    typedef typename channel_convert_to_unsigned<d_channel_t>::type channel_t;

    typedef typename image_type<channel_t, gray_layout_t>::type gray_image_t;

    typedef typename gray_image_t::value_type gray_pixel_t;

 

    gray_image_t ccv_image(src.dimensions());

    copy_and_convert_pixels(src, view(ccv_image));

    x_gradient(const_view(ccv_image), dst);

}

 

Thanks,

Mark
