ROIs are drawn on an image using the ROI tools at the top of the tool bar on the Openlab image document window. There is a choice of shape, including a freehand, a lasso and a wizard ROI.

If you find that your ROI won't retain the shape you have drawn is that you may have mistakenly selected the lasso ROI rather than the freehand ROI.
