I'm very new to WPF and trying to port an application from VB6 to C# and XAML. What I need to do now is create one big image out of a number of small ones, arranged like a series of "tiles." Some of these smaller ones will have overlays superimposed on them. In VB6, accomplishing both the tiling and overlaying would simply be a matter of using the PaintPicture method with the PictureBox control. This is my attempt at the tiling and overlaying in one step (though really the overlaying could occur beforehand): ImageDrawing Drawing1 = new ImageDrawing(new BitmapImage(new Uri(@"c:\one.bmp", UriKind.Absolute)), new Rect(0, 0, 40, 130)); ImageDrawing Drawing2 = new ImageDrawing(new BitmapImage(new Uri(@"c:\two.bmp", UriKind.Absolute)), new Rect(40, 0, 45, 130)); ImageDrawing Drawing3 = new ImageDrawing(new BitmapImage(new Uri(@"c:\overlay.bmp", UriKind.Absolute)), new Rect(40, 0, 45, 130)); DrawingGroup myDrawingGroup = new DrawingGroup(); myDrawingGroup.Children.Add(Drawing1); myDrawingGroup.Children.Add(Drawing2); myDrawingGroup.Children.Add(Drawing3); myImage.Source = new DrawingImage(myDrawingGroup); The tiling works fine, but the overlay is a no-go. I was wondering if someone could point me towards a means of accomplishing the overlays and someone could indicate whether this is the best way to do the tiling. Thanks!!
