ColorManagementEffectAlphaMode Property |
Namespace: Microsoft.Graphics.Canvas.Effects
Effect inputs and outputs are assumed to be in premultiplied alpha format, so when this property is set to Premultiplied, color management is applied directly to the input values with no extra conversions.
If AlphaMode set to Straight, input values will be unpremultiplied, then the color management applied, and finally the result converted back to premultiplied format.
