AnnD2DObjectRenderer Class

Summary

Base class for all object renderers.

Syntax

public abstract class AnnD2DObjectRenderer : IAnnObjectRenderer

Public MustInherit Class AnnD2DObjectRenderer  
   Implements IAnnObjectRenderer

Remarks

The AnnD2DObjectRenderer is the default renderer for the annotation objects in this platform. 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.

AnnD2DObjectRenderer 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	Called by the framework to render the rotation center and gripper thumbs when the object is in a selected state.
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.
