====== Region of interest ======

In **Autoscaling** regime the color palette is automaticaly spreaded out to the whole range of height values on the image (the same will happen if you do the double-click on the palette in **Fixed scale** regime). You can specify a certain part of the image as a base for autoscaling -- this will be the **region of interest**.

To specify the region, select it with one of the standart selection tools and then press the tool bar button:

{{:en:processing:button_region_of_interest.jpg|Region of interest button}}

You can also call this function from the menu [[view|View]] -> **Region of interest**.

The selected area will be heilighted with red line. Use [[настройки_изображения|image settings]] to remove the line:

{{:en:processing:region_of_interest.jpg|}}
