Renders this thumb at the specified center location.
public void Render(
Sub Render( _
ByVal renderer As IAnnObjectRenderer, _
ByVal mapper As AnnContainerMapper, _
ByVal location As LeadPointD, _
ByVal operations As AnnFixedStateOperations _
The object renderer being invoked. This value must not be null.
The mapper object to use for converting coordinates. This value must not be null.
The center location of the thumb in container coordinates.
The fixed state of the owner object.
This method is called by renderer from the IAnnObjectRenderer.RenderThumbs and IAnnObjectRenderer.RenderRotatePointThumbs methods. The framework will call these methods to render the selected and rotation thumbs of an object.
This IAnnThumbStyle perform the following during this method:
Converts the center location into physical coordinates using mapper.PointFromContainerCoordinates and Size into physical coordinates using mapper.SizeFromContainerCoordinates and then creates a rectangle for converted location and size (with its origin at the location).
Calls AddPath passing the rectangle calculated above to allow the implementation class to draw the actual thumb shape
