Currently, I have a RasterThumbnailBrowser and a RasterImageViewer Object in window form.
When user select a image from the RasterThumbnailBrowser, the corresponding image will be displayed in the RasterImageViewer.
Then, the user draw some annotations (from the Default Tool Bars of AnnAutomationManager) on the image of the viewer. e.g. draw a line annotation.The user then select another image for drawing another annotation. However, the line annotation still exist in the second image.

How can I remove/refresh the annotation?

Currently, i have to delete the link of RasterImageViewer and the AnnAutomationManager by disposing the automation object.

Do you want to discard the annotation objects when the image changes, or do you want to keep them associated with the original image on which the user drew them?

Let's say you have an AnnAutomation object called annAuto.  If you want to discard all the annotation objects, you can just call annAuto.Container.Objects.Clear().  This will remove all the annotation objects without having to destory/create any resources or objects.
