minmax - Forced write of the minimum and maximum data header values
MINMAX sets the DATAMIN and DATAMAX items in an image in those rare
cases that you need it computed from a selected area. Most commonly
when data have been flagged (e.g. with MATHS or IMFLAG).
See also PUTHD on how to patch a user supplied value for DATAMIN
If the min/max was found to be the same, nothing will be done to
The input dataset name. No default.
The region of interest over which the min and max are to be computed.
Full region specifications are supported.
See the Users Manual for instructions on how to specify this.
Default: the whole dataset
If supplied, this is a fast way to set a new value for the min and
max as you want them. There is no checking if the values are
correct, or even if ``min < max''.
Default: not used.
