Description: Invert the grey-range of a grey-level woolz object writing the new object to standard output. The original grey-values are transformed from their original range. The transformation is
\[ g_{out} = g_u + g_l - g_{in} \]
where \(g_{out}\) is the new grey value, \(g_{in}\) is the given grey value, \(g_u\) is the upper grey value and \(g_l\) is the lower grey value.

Examples

WlzGreyInvert -u 255 -l 0 in.wlz >out.wlz

Inverts the grey valued object read from in.wlz so that its values are inverted and in the range 0 - 255. The resulting object is then written to out.wlz.
