Imaging extensions (files ending in the extension IEDLL) are used to extend the image processing capabilities of the XrayVision® (XV) application. These add-on extensions include operations like whitening and cosmetic imaging. By utilizing imaging extensions, users are able to add newer and more powerful image processing techniques as they come available. Existing XV installations can instantly add imaging extensions simply by running the corresponding upgrader from Apteryx's Add-ons and Components upgrade web site located at http://www.apteryx.com/software-updates.
