A very large image might not load in Image Viewer, or if the image does load, zooming and panning can be slow. In either case, creating a reduced resolution data set (R-Set) can improve performance. Use the Image Viewer to navigate an R-Set image the same way you navigate a standard image.

A reduced resolution (R-Set) file creates a smaller version of an image file by dividing the image into spatial tiles and resampling the image.
Using larger block sizes reduces overall computation time but requires more memory to process each block.
To work with image data in file formats not supported by block processing functions, construct a class that manages files based on region.
