Hi, I wrapped boost::gil::rgb8_image_t::view_t as a simple class Image: class Image { public: // ... some methods here. private: boost::gil::rgb8_image_t::view_t view; }; And I have a method Crop, which is crop image to other image object, like this: void Image::Crop(int x, int y, int width, int height, Image& out) const { boost::gil::rgb8_image_t s(width, height); boost::gil::copy_pixels( boost::gil::subimage_view(view, x, y, width, height), boost::gil::view(s)); out.view = boost::gil::view(s); } I will get error after I run this code... But I can't understand what's wrong. So, how can I implement this? Thank you very much. -- View this message in context: http://www.nabble.com/-GIL--How-can-I-copy-a-subimage_view-to-a-view--tp2323... Sent from the Boost - Users mailing list archive at Nabble.com.
