Blocked Images

Read and navigate very large images

A very large image may not fit into memory, which makes it challenging to display and process. The blockedImage object solves this problem by representing an image as a collection of smaller blocks of data that can be independently loaded and processed. A blockedImage object can support large images and images with one or multiple resolution levels.
