}
Expand description
How the alpha values of the pixels of the window are treated.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Opaque = 1
The alpha channel of the image is ignored. All the pixels are considered as if they have a value of 1.0.
PreMultiplied = 2
The alpha channel of the image is respected. The color channels are expected to have already been multiplied by the alpha value.
PostMultiplied = 4
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 = 8
Let the operating system or driver implementation choose.
