Out of Range Tool

The Out of Range tool uses pseudo colors to display pixels above or below user specified threshold. It is also capable of outputting a mask of the out-of-range pixels or its inverse, so that corrective action can be taken by other tools downstream. The Out of Range tool is in the Channel folder in the Tools tab.

The Out of Range tool has the following parameters:

Channel Select the source image channel to analyze.
Minimum Set the minimum value threshold of the source image channel.
Maximum Set the maximum value threshold of the source image channel.
In Range RGB Select the source image channel to display as the “In Range” color or deselect to use arbitrary color.
In Range Alpha Select the source image alpha channel to display as the “In Range” alpha or deselect to use arbitrary alpha value.
Below Range Select color to display pixels below the specified threshold.
In Range Select color to display pixels within the specified threshold.
Above Range Select color to display pixels above the specified threshold.
