Enum vulkano::swapchain::CompositeAlpha[−][src]

#[repr(u32)]
pub enum CompositeAlpha {
    Opaque,
    PreMultiplied,
    PostMultiplied,
    Inherit,
}

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.
