Applies the
current look-up table function to each pixel in the current selection
(or the entire image if there is no current selection) and restores the
default look-up table (the identity function). This modifies the gray
values so that when the image is viewed using the default grayscale
look-up table it will look the same as it did before. It also makes any
brightness and contrast changes permanent. It can be used to posterize
(reduce the number of gray values) an image by loading and applying,
for example, a LUT consisting of four shades of gray. It can also be
used to convert color images to grayscale, and to convert a thresholded
image to binary. If density slicing is in effect, a dialog box is
displayed, allowing you to process highlighted pixels in one way, and
all other pixels another way.
