Invert

This command inverts or creates an effect similar to negative film for all scan
jobs.
Original Inverted image
Take note that all scan jobs are inverted at the same time; you cannot invert an
individual scan job alone.
When an image is inverted, the brightness value of each pixel is converted to its
inverse value. In the case of 24-bit images, 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.
To use this feature:
Choose the Invert command in the Preferences menu. A check mark is shown
before the command when it is enabled.
