Any idea for custom PictureMarkerSymbol to rounded corner picture.

[baohuachu3]

I want the symbol to show the picture to rounded corner. In html can set css to the border-radius. While js api is not supported for this customization. 

 The css for rounded corner image effect should like this: http://jsfiddle.net/YhDXm/1276/

You can use a round image, like this: https://codepen.io/solowt/pen/EbVRMJ?editors=1000#0 

S ome images may seem round, but actually have a white (or some other color) background.  But you can have images with no background and a centered circle.
