Detailed Description

read an image from a file

vil_load returns a pointer to the base class of a vil_image_view object. You can then cast, or assign it to the appropriate type. You must not forget to delete the created view.

vil_load_image_resource() returns a smart pointer to vil_image_resource which will "read an image from a file". In practice it may or may not read the image on creation, but a disk read will take place at some point before get_view() returns.
