06-24-2008, 10:14 delemed Joined on 04-11-2008 Posts 19 Control the repaint Im working with an RasterImage (displayed in an RasterImageViewer) on which I would like to draw different objects like rectangles, circles etc... How can I handle the repainting of the image in a smart way? Is it possible to repaint only single regions of an RasterImage? Is it possible to stop the "auto-redraw" of my RasterImage or the RasterImageViewer and handle it by myself? RasterImaging Pro V15 Greets Jonas    Report

If you want to do completely manual painting, you can use the RasterImage.Paint method.  If you did this, you will probably not want to use the RasterImageViewer because you'll have to fight with its events.
