Invert - Microtek ScanMaker 35T Plus User Manual

Invert

This command creates a negative of an image. The Invert effect is applied to
the whole preview image; it cannot be used for only a specific portion of the
image.
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.
