Invert - Microtek ScanMaker 6400XL Reference Manual

Invert

This command creates a negative of an image. The Invert effect is applied to all
scan jobs, not just the selected scan job.
When an image is inverted, the brightness value of each pixel is converted to the
inverse value on the 256-step color values scale. For example, a pixel in a
positive image with a value of 255 is changed to 0, and a pixel with a value of 5 is
changed to 250.
