97 Basically, a blend mode sets the alpha blending equation for plane
98 composition that fits the mode in which the alpha channel affects the state of
100 example, consider the following elements of the alpha blending equation:
103 - *fg.alpha*: Alpha component value from the foreground's pixel.
105 - *plane_alpha*: Plane alpha value set by the **plane "alpha" property**, see
108 in the basic alpha blending equation::
110 out.rgb = alpha * fg.rgb + (1 - alpha) * bg.rgb
112 the alpha channel value of each pixel in a plane is ignored and only the plane
113 alpha affects the resulted pixel color values.
