Enum nvtt_rs::AlphaMode

pub enum AlphaMode {
    None,
    Premultiplied,
    Transparency,
}

Specifies how the alpha should be interpreted on the image.

You can view wikipedia for more information about alpha blending.

Variants

None

The image does not contain any alpha information.

Premultiplied

The image uses premultiplied alpha.

Transparency

The image uses straight alpha, where the color channels represent the straight color of the channel without transparency.
