Parameters

surface  SKSurface

An SKSurface instance, whose data is about to be accessed.

backColor  SKColor  (Optional)

Determines the BackColor property of the result. When setting pixels of bitmaps without alpha support, specifies the color of the background. Color values with alpha, which are considered opaque will be blended with this color before setting the pixel in the result bitmap data. The Alpha property of the specified background color is ignored. This parameter is optional.
Default value: The bitwise zero instance of SKColor, which has the same RGB values as Black.

alphaThreshold  Byte  (Optional)

Determines the AlphaThreshold property of the result. Can be relevant in some operations such as when drawing another IReadableBitmapData instance with alpha into the returned bitmap data by the DrawInto extension methods and the specified surface has no alpha support. This parameter is optional.
Default value: 128.
