Examples of ROI

com.lightcrafts.mediax.jai.ROI
The parent class for representations of a region of interest of an image (currently only single band images with integral data types are supported). This class represents region information in image form, and can thus be used as a fallback where a Shape representation is unavailable. Where possible, subclasses such as ROIShape are used since they provide a more compact means of storage for large regions.
The getAsShape() method may be called optimistically on any instance of ROI; however, it may return null to indicate that a Shape representation of the ROI is not available. In this case, getAsImage() should be called as a fallback.
Inclusion and exclusion of pixels is defined by a threshold value. Pixel values greater than or equal to the threshold indicate inclusion.
