The Alpha field of the MaskMode enumeration specifies that the alpha channel values of the mask layer image should be used as the mask values. This is useful when you want to apply a mask based on the transparency of the image, allowing for complex masking effects based on the image's alpha channel.
Use MaskMode.Alpha when you need to apply a mask using the alpha channel of an image. This is typically used in UI design where you want to create effects such as fading or transparency-based masking.
// Example of using MaskMode.Alpha in a UI component var myComponent = new UIComponent(); myComponent.MaskMode = MaskMode.Alpha; // Assuming myComponent has a mask image set, the alpha channel of that image // will be used to determine the masking effect.
