==== Protected Methods ====
** {{wiki:ProtectedMethod.gif|}} DrawCore(GeoCanvas,Collection<SimpleCandidate>) **

  * //This method draws the Layer.//
== Remarks ==
  * //This abstract method is called from the concrete public method Draw. This method draws the representation of the layer based on the extent you provided. When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.//

== Parameters ==
  * //canvas//
    * Type:[[ThinkGeo.MapSuite.Core.GeoCanvas|GeoCanvas]]
    * Description:This parameter is the canvas object or a GeoImage to draw on.
