public class RasterImageGdiPlusGraphicsContainer : IDisposable This class holds the System.Drawing.Graphics, System.Drawing.Image and System.Drawing.Region representation of the surface of the Leadtools.RasterImage.
You can then use the members of the RasterImageGdiPlusGraphicsContainer along with GDI+ calls to draw on the surface of the Leadtools.RasterImage.
You can also use the RasterImagePainter.CreateGraphics method to create a GDI+ Graphics object from a Leadtools.RasterImage.
For more information refer to RasterImage and GDI/GDI+.
