| Leadtools.Annotations.Rendering Namespace : AnnD2DObjectRenderer Class |
public abstract class AnnD2DObjectRenderer : Leadtools.Annotations.Core.IAnnObjectRenderer
'Declaration
Public MustInherit Class AnnD2DObjectRenderer Implements Leadtools.Annotations.Core.IAnnObjectRenderer
'Usage
Dim instance As AnnD2DObjectRenderer
public sealed class AnnD2DObjectRenderer : Leadtools.Annotations.Core.IAnnObjectRenderer
function Leadtools.Annotations.Rendering.AnnD2DObjectRenderer()
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.
