Extracting ROI without IDL objects is it possible [message #37731]

I'm having a little trouble with extracting ROI with IDL. I'm trying to make
a little application for temporary use while I don't learn how to manage
IDLanROI objects.

Suppose I have a variable image from I want to extract the ROI and that I've
defined a draw with widget_draw function. Then I make:

ROI=cw_defroi(draw) ;and here I draw my region of interest

How can I visualize my region of interest

I can define a second image, per example image2=FLTARR(xdim, ydim)

And make image2=image(ROI) and do TV, image2 and I see only my roi but I
want to see both, i. e., the roi over the image, perhaps with another colour

(cw_defroi does it in part, but I want save those roi indeces and calling
back in the future and also apply from the window that defines the roi to
others)

It would help another thing, get the boarders of the roi, and make it red,
blue, white.

Cheers,

N.
