Members 
Base class for all HTML 5 Canvas object renderers.
Syntax
function Leadtools.Annotations.Rendering.AnnObjectRenderer() 
Remarks

The AnnObjectRenderer is the default renderer use with AnnHtml5RenderingEngine. This is an abstract class that implements most common operations, while actual rendering of the object is implemented in the derived class for the objects.

AnnObjectRenderer contains the following members:

Member Description
Render

Called by the framework to render an annotation object.

LabelRenderer

Used by the Render method to render the text labels of the object.

RenderThumbs

Called by the framework to render the thumbs of an annotation object when the object is in a selected state.

LocationsThumbStyle

The style to use in RenderThumbs.

RenderRotatePointThumbs

RotateCenterThumbStyle and RotateGripperThumbStyle

The style to use in RenderRotatePointThumbs.

RenderLocked

Called by the framework to render the locked portion of the object.

When implementing user-defined annotations, one of the objects required is a renderer for the new object type. You can derive your renderer from this class and use its helper methods. For more information, refer to Implementing User-Defined Objects With LEADTOOLS Annotations.
