Re: Getting viewport coordinates

/Hello

Use the NCL statement "getvalues'
http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclStatements.shtml

/

      getvalues

Use *getvalues* to retrieve resource values from HLU objects. It is
different than the *setvalues* and *create* NCL resource list because it
requires an identifier rather than an expression after the colon.
*getvalues* functions identically to the assignment
<http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclStatements.shtml#Assignment>
with respect to how it assigns values to the identifier.

      getvalues /obj_reference/
            /resource_string/ : /identifier/
      end getvalues

================================================
/ getvalues contour /
        /"vpXF" : vpx /
/ "vpYF" : vpy /
/ "vpWidthF" : vpw /
/ "vpHeightF" : vph /
 /end getvalues /
//
Good Luck
