vil_image_resource_sptr vil_new_image_resource_of_view ( vil_image_view_base const & view ) [friend]

Make a new image resource that is a wrapper on an existing view's data.

Note:: The output will be a shallow copy of the input, so changing the pixel values of one may change the pixel value of the other. Thanks to the magic of smart pointers, the output will remain valid even if you destroy the input. When you wrap a multi-component image in this way, the vil_image_resource API will treat it as a scalar pixel image with multiple planes. (This doesn't affect the underlying data storage.)
