How Can I draw the Roi on overlay

[Mohamed Tleis]

Dear Members,

I was using the drawPixels to draw over my images, but I decided to use
overlays.

roi.drawPixels(ip);

I succeeded initially in drawing a rectangle Roi over the image, using the
Overlay.add(roi) method, but this isn't working on the non-rectangular
rois; Any ideas?

Best Regards,
