Synopsis
WlzGreySetRange [-u#] [-l#] [-U#] [-L#] [-h] [-v] [<input file>]
Options
-h Help, prints usage message.
-d Dither values.
-v Verbose operation.
-l Low grey value in source image, default min value in source.
-L Low grey value in destination image, default 0.
-u Upper grey value in source image, default max value in source.
-U Upper grey value in dest image, default 0.
Description
Sets the grey-range of a grey-level woolz object riting the new object to standard output. The original grey-values are linearly transformed from their original range. The transformation is

g_{out} = (\frac{U - L}{u - l})g_{in} + L new_grey = ((U - L)/(u - l))*old_grey + L

where U and L are the new upper and lower values and u and l are the old upper and lower values. If u and l are set it is up to the user to ensure that the actual image values are within the range [u,l]. Use WlzGreyRange to check.
