No-Data Overlay |

#### No-Data Overlay

Toggles the overlay of the no-data mask within a band's Image View. The overlay style properties can be modified using the no-data overlay page in the Options Dialog.

The no-data mask overlays displays all the band's pixels with undefined sample values. In order to control no-data pixels, use the band's `no-data value` and/or the band's `valid pixel expression` in the Property Editor for the selected band.
