Examples of RoiShape

com.lightcrafts.mediax.jai.ROIShape
A class representing a region of interest within an image as a Shape. Such regions are binary by definition. Using a Shape representation allows boolean operations to be performed quickly and with compact storage. If a PropertyGenerator responsible for generating the ROI property of a particular OperationDescriptor (e.g., a warp) cannot reasonably produce an ROIShape representing the region, it should call getAsImage() on its sources and produce its output ROI in image form.
