2.3.7 Blending

+ +

Rendering a scene often involves drawing layers of objects that +overlap each other. Blending determines how two overlapping pixels +are combined in the final image that is rendered to the screen. +Chickadee provides the following blend modes: +

replace +Use the latest color, ignoring all others. + +
alpha +Blend pixels according to the values of their alpha channels. This is +the most commonly used blend mode and thus is Chickadee’s default +mode. + +
add +Add all pixel color values together. The more colors blended +together, the more white the final color becomes. + +
subtract +Subtract all pixel color values. The more colors blended together, +the more black the final color becomes. + +
multiply + +
darken + +
lighten + +
