InvertOriginal
To use this feature:
Choose the Invert command in the Preferences menu. A
check appears next to the command when it is enabled.
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.
