Re: [boost] [gil] numeric extensions pixel division.

26 Mar 2013

      Yes,

That is what I mean, and we have something very similar
herehttp://svn.boost.org/svn/boost/trunk/boost/gil/extension/numeric/pixel_numer...for
operations like addition, substraction of pixels, also for
multiplication and division by scalars too. But why not for division?

Thanks Chris.

Hey,
It seems that in the numeric extensions it is implemented the division of
channels, but not the division of pixels. Are you planning to include it
at
some point?
I'm not sure what the numeric extension has to do with division of
channels?
When you say "division of pixel" do you mean the division of all
channels in a pixel?
you can do that like this:
typedef rgb8_pixel_t pixel_t;
pixel_t a( 10, 20, 30 );
    pixel_t b( 10, 20, 30 );
static_for_each( a, b, [] ( channel_type< pixel_t >::type& a
                              , const channel_type< pixel_t >::type& b
                              )
        {
            a /= b;
        } );
Hope that helps,
Christian
