09-02-2008, 3:35 roadman Joined on 06-27-2007 Posts 104 Display annotation per image 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?      Report
