Command line: INVERSION
This functionality is available only in the Raster module.
Inversion changes the color value of each point of a monochrome image to the opposite (creates a “negative image”). The background points become the image points, and the points transmitting the image of the objects - the background ones. The figure below shows the result of applying the filter.
