Hi All

I'd like to return the perimeter of a wand selection as a variable in my
macro.  So far, all I can get is

getSelectionCoordinates(xCoordinates, yCoordinates);
perimeter = lengthOf(xCoordinates);

which is not correct as edge pixels should be counted as sqrt(2).

How can I get a similar result to:
*getTracedPerimeter()

in a macro?
