Domain type Picture

Picture domains are designed for raster maps which use a maximum of 256 different colors. You should use a picture domain for example for scanned pictures, i.e. when a raster map contains merely colors and when the pixels do not have a meaning in the sense of classes or values.

A picture domain can only be used by raster maps.

The colors in a picture domain are defined by Red, Green and Blue values, each ranging from 0 to 255. For example, orange is defined by (255, 128, 0) meaning 255 Red, 128 Green and 0 Blue.

You can convert a picture domain to a class domain: in the Properties dialog box of a picture domain, click the Convert to classes button.
