2.3.9 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
• screen
