Detailed Description

A vil_image_resource to a frame of a vidl_istream.

With this class you can create image resources to several frames of an open vidl istream. When get_view is called the stream is seeked to the relevant frame number and the frame is decoded and converted to an image view. The stream must be seekable unless views are requested in sequential order. The stream is closed when all image resources using it are destroyed.
