A very large image may not fit into memory, which makes it challenging
to display and process the image. The
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.
If you want to interact with a large image using the Image Viewer app, then you may notice that zooming and panning actions can be slow, or the image may not load. If this happens, create a reduced resolution data set (R-Set) to improve performance. You can use the Image Viewer to navigate an R-Set image the same way you navigate a standard image.
