Object.defineProperty('PremultiplyAlpha');
This property is only supported in Silverlight versions. This property only applies to 32-bit images. This property only has an effect when using WriteableBitmap for memory storage of the image data.
When this property is set to True, LEADTOOLS will automatically do the required conversions to store premultipled alpha values into the WriteableBitmap. If you are dealing with 32-bit images that do not have meaningful alpha channel values, you should simply set this property to false.
Setting this property to True will slow down image processing functions. You should only use this if you know your images have meaningful alpha channel values.
