Enum crow::BlendMode

#[non_exhaustive]
pub enum BlendMode {
    Alpha,
    Additive,
}

Used in DrawConfig to specify how each pixel should be draw onto the target.

Variants (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.

Alpha

src_alpha * src_color + (1.0 - src_alpha) * dst_color

Additive

src_alpha * src_color + 1.0 * dst_color
