Workaround
There are several options when referring to images used as the Source for a PictureMarkerSymbol:Note:- The following examples assume the image is in a folder called "Images".#1. The image is included in the project and the Build Action is "Resource": Use the Pack URI scheme e.g.:BitmapImage bi0 = new BitmapImage();bi0.BeginInit();bi0.UriSource = new Uri("pack://application:,,,/Images/MyImage.png");bi0.EndInit();PictureMarkerSymbol pms = new PictureMarkerSymbol();pms.Source = bi0;#2. The image is included in the project and the Build Action is Content: Use absolute Uri e.g.:Note:- Ensure image is in output location (set Copy to Output Directory to "Copy if Newer" / "Copy Always")BitmapImage bi0 = new BitmapImage(new Uri(Path.Combine(Environment.CurrentDirectory, "Images", "MyImage.png")));PictureMarkerSymbol pms = new PictureMarkerSymbol();pms.Source = bi0;#3. Image is in memory (or needs to be modified in memory):ImageBrush simpleArrow = new ImageBrush();simpleArrow.ImageSource = new BitmapImage(new Uri("<a href="http://static.arcgis.com/images/Symbols/Basic/ArrowYellow.png" target="_blank">http://static.arcgis.com/images/Symbols/Basic/ArrowYellow.png</a>"));// Add an Ellipse Element & use the ImageBrush as the Fill for the EllipseEllipse myEllipse = new Ellipse();myEllipse.Fill = simpleArrow;myEllipse.HorizontalAlignment = HorizontalAlignment.Center;myEllipse.VerticalAlignment = VerticalAlignment.Center;myEllipse.Width = 24;myEllipse.Height = 24;// Rotate by the angle 90 and about the center of the 24x24 pixel image.myEllipse.RenderTransform = new RotateTransform(90, 12, 12);//Force a rendermyEllipse.Measure(new System.Windows.Size(Double.PositiveInfinity, Double.PositiveInfinity));myEllipse.Arrange(new Rect(myEllipse.DesiredSize));RenderTargetBitmap render = new RenderTargetBitmap(34, 34, 96, 96, PixelFormats.Default);render.Render(myEllipse);PictureMarkerSymbol pms = new PictureMarkerSymbol();pms.Source = render;Steps to Reproduce
