Use the Image Viewer app to view and explore images. Image Viewer includes tools that you can use to examine image pixels in detail, crop an image, adjust image contrast, and measure distances between pixels. Use the imtool function to launch Image Viewer.

If you want to interact with a large image using Image Viewer, 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 Image Viewer to navigate an R-Set image the same way you navigate a standard image.
