Large Image Files

Read and navigate very large images

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.

Create and Open Reduced Resolution Files

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.
