    sizeType: String - can be "stdDeviation" (from SVG), "radius" (from Silverlight), "pixelRadius" (from VML) (default = "stdDeviation")

shadow: Object
    dx: Integer - sets x-axis offset (default = 4)
    dy: Integer - sets y-axis offset (default = 4)
    size: String - sets shadow size, can be float or "none" (default = 2.5)
    sizeType: String - can be "stdDeviation" (from SVG), "radius" (from Silverlight), "pixelRadius" (from VML) (default = "stdDeviation")
    color: Array|String|Object (dojo.Color) - sets shadow color (default = [0,0,0,0.5])

FAQ

Q: Why does the blur effect not work with the Canvas renderer?
A: Canvas doesn't support a stand-alone blur effect.

Q: Why doesn't my Silverlight blur work?
A: Silverlight version 3 or higher is required for blur.

Q: Why doesn't my Silverlight object show multiple effects?
A: Silverlight currently only supports one effect per object.

Q: Why is my opacity missing with the VML renderer?
A: If setFill occurs after setBlur, it will override the opacity. Make sure to use setBlur after setFill. See dojox.gfx.plugins.Blur.js file for a workaround fix.

Q: Why doesn't the blur effect work in Safari?
A: Safari doesn't currently implement feGaussianBlur properly. Use WebKit nightly instead.

Q: Why isn't the shadow blurred using the VML renderer?
A: VML doesn't support shadow blur.

Q: Why does the shadow sometimes appear through the original object using the Canvas renderer?
A: Good question. Setting globalCompositeOperation="lighter" helps a little but I'm sure there's a better answer.
