IALOG-Takes the antilog of an image

Description:
IALOG takes the base 10 antilog of each pixel in an image. Each pixel in the output image takes the value 10 to the power of the corresponding pixel in the input image.

Parameters:
IMAGE
The datafile to be processed.
OUTPUT
The name of the resulting image. If this is the same as IMAGE (the default) the operation will be performed in situ. Otherwise a new image will be created.
