I tried to do a fill_pixels, but the thing is I get an error (because I am doing special things) on something like this:

        typedef pixel<bits32f, devicen_layout_t< num_channels<View>::value > > comp_pixel_t;
        typedef image<comp_pixel_t, false, std::allocator<unsigned char> > comp_image_t;
        typedef typename view_type_from_pixel<comp_pixel_t>::type comp_view_t;
        typedef typename comp_view_t::x_iterator tmp_iterator;

        comp_image_t itmp( dst.dimensions( ) );
        comp_view_t tmpv( view( itmp ) );
        fill_pixels(tmpv, 0);

But this is not working...

Anyway,
thank you
Eloi.

Hi Eloi, for performance reasons gil is not initializing the array
with a default value. Also, I wouldn't trust the compiler to do
anything special since it might be different from platform to
platform. Just call fill_pixels which in your case ( rgb32f_image_t )
should be reduced to a memset call.

Regards,
Christian
