Re: [Boost-users] [GIL] Change layout type of a pixel...

I see. Do you still have problems then? No, it is okay, my code is working now :)

For the hsl color space, we probably should have it for double ( hsl64f_pixel_t ), as well, I suppose. Yes, that could be a good idea, but 32f is enough for our needs I think. But good question, I will answer my friends what do they think of that (according to their needs).

Thank you, you are totally right for hsl :). I didn't saw that... I found how to do what I need for other cases:

typedef pixel::type, rgb_layout_t > rgb_pixel_t;

Hi Eloi,

for homogeneous pixel types ( like rgb8_pixel_t ) or packed_pixel types there is no bits member. Can you describe what you want in more detail? Also hsl pixel is only defined for 32f ( hsl32f_pixel_t ).

Hi all,

I would like to know how to change the layout of a given pixel type. For example, I would like to do something like:

// Pixel = rgb16_pixel_t for example. template<class Pixel> void foo(Pixel & A) { typedef typename pixel::type hsl_pixel_t; hsl_pixel_t a; color_convert(A, a); }

Thank you by advance, Eloi.
