Large Image Files

Read and navigate very large images

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