Property Value
true automatically detect if the image has meaningful alpha channel values; false otherwise.This property is only supported in Silverlght versions of LEADTOOLS.
This property only has an effect when using a Silverlight WriteableBitmap object for image data storage.
Setting this property to true can slow down image loading and image processing. If you know that your images have meaningful alpha channel values or if you know that your images have only 0xFF for alpha channel values, set this property to false.
When this property is true, LEADTOOLS will detect if the loaded image data contains meaningful alpha channel values and then set the RasterImage.PremultiplyAlpha property accordingly.
Target Platforms: Silverlight, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
