Remarks

The AnnObjectRenderer 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.

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

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.

RenderSelection

Called by the framework to renders the selected part of this object if it supports a selection stroke.

RenderAlignmentTarget

Called by the framework to highlight rectangle above the bounds of alignment target object when EnableObjectsAlignment is turned on and the object is target alignment.

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 Implement User-Defined Annotations - WinForms C# .NET 6.
