Enum ColorMatrixAlphaMode 

pub enum ColorMatrixAlphaMode {
    Premultiplied,
    Straight,
}

How a ColorMatrix treats the premultiplied colours it is applied to (Win2D CanvasAlphaMode of ColorMatrixEffect.AlphaMode, Direct2D’s D2D1_COLORMATRIX_ALPHA_MODE).

Variants

Premultiplied

The colour is un-premultiplied, the matrix applied to [R, G, B, a, 1] and the result premultiplied again (the Win2D default).

Straight

The matrix is applied to the premultiplied colour as it is, [R a, G a, B a, a, 1], and the result taken as premultiplied (its colour clamped to its alpha).
