pub enum CompositeAlpha {
Opaque,

PostMultiplied,
Inherit,
}
Expand description
How the alpha values of the pixels of the window are treated.
Variants
Opaque
The alpha channel of the image is ignored. All the pixels are considered as if they have a value of 1.0.
PreMultiplied
The alpha channel of the image is respected. The color channels are expected to have already been multiplied by the alpha value.
PostMultiplied
The alpha channel of the image is respected. The color channels will be multiplied by the alpha value by the compositor before being added to what is behind.
Inherit
Let the operating system or driver implementation choose.
