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<hsl_t, Pixel::bits>::type hsl_pixel_t; hsl_pixel_t a; color_convert(A, a); } Thank you by advance, Eloi.
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 ). Regards, Christian On Tue, Dec 15, 2009 at 11:01 AM, Eloi Du Bois <eloi.du.bois@gmail.com> wrote:

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<typename channel_type< Pixel >::type, rgb_layout_t > rgb_pixel_t; 2009/12/15 Christian Henning <chhenning@gmail.com>

I see. Do you still have problems then? For the hsl color space, we probably should have it for double ( hsl64f_pixel_t ), as well, I suppose. Christian On Wed, Dec 16, 2009 at 4:24 AM, Eloi Du Bois <eloi.du.bois@gmail.com> wrote:

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).
