cw_defroi vertices. [message #30365]

Hi All,

I have been using DEFROI to define a region of interest, and then
using xVerts and yVerts in the line that follows:

area=DEFROI(m,n,xVerts,yVerts)
ROI=OBJ_NEW('IDLanROI', xVerts, yVerts, type=2); type two
;is a closed polygon

I want to be able to use cw_defroi instead because I am updating a
draw widget.
Something like
area = cw_defroi(info.drawID)

Obviously xVerts and yVerts are no longer defined, and it seems that
the "area" array is the wrong dimensions to be used with the "data"
keyword in the initialization of "ROI" (above).

Does anyone know how I should input the vertices of the region of
interest when initializing "ROI"?

TIA
Dave Higgins
