Hi,

I have been trying to create a new Custom Annotation and have managed to get it working, however I found that when toggleing the Visible option the Annotation appears to still be there (although not selectable). It looks like the Annotation is burnt into Layer!

 I tried this on the DotAnnotateDemo app using the Custom Triangle Annotation and it does the same.

Is there a fix for this? or is there somethign extra that the Custom Annotation needs to force the Layer to be refershed?

 Thanks,

 Louis

public class TriangleRenderingEngine : Atalasoft.Annotate.Renderer.AnnotationRenderingEngine

public TriangleRenderingEngine()

// We will use our own custom grip renderer.

// We could simply override the RenderGrips method as well.

//this.GripRenderer = new MyCustomGripRenderer();

public override void RenderAnnotation(AnnotationData annotation, Atalasoft.Annotate.Renderer.RenderEnvironment e)

// Perform a basic check.

TriangleData data = annotation as TriangleData;

if (data == null) return;

if (data.Fill == null) return;

if (annotation.Visible == false) return;

// SetGraphicsTransform handles combining multiple

// transformation matrix objects so you can render normally.

base.SetGraphicsTransform(annotation, e);

Brush b = CreateBrush(data.Fill);

Hope this solves your problem.
