Re: [Boost-users] [GIL] Black filled or not ?

Please use: fill_pixels( tmpv, comp_pixel_t( 0.f, 0.f, 0.f )); This call wont be a memset unfortunately. But you could always just get the char* and memset yourself. Regards, Christian On Wed, Jan 13, 2010 at 11:40 AM, Eloi Du Bois wrote:

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

...

comp_pixel_t;         typedef image comp_image_t;         typedef typename view_type_from_pixel::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

Hi all !

I would like to know, when creating an image like that: rgb32f_image_t img(w, h);

is the image filled with 0 by default or should I call fill_pixels ?

Thank you ! Eloi.
