Draw(GeoCanvas)

• This method draws the Overlay.

• This method is the concrete wrapper for the abstract method DrawCore. This method draws the representation of the overlay based on the extent you provided. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.
