Constants
- ABOVE → const BlendMode
- The display object appears above the background. Pixel values of the display object are invisible where the backround is transparent.
- ADD → const BlendMode
- Adds the values of the constituent colors of the display object to the colors of its background, applying a ceiling of 0xFF.
- BELOW → const BlendMode
- The display object appears in behind the background. Pixel values of the background object override those of the display object. Where the background is transparent, the display object is visible.
- ERASE → const BlendMode
- Erases the background based on the alpha value of the display object.
- MULTIPLY → const BlendMode
- Multiplies the values of the display object constituent colors by the colors of the background color, and then normalizes by dividing by 0xFF, resulting in darker colors.
- NONE → const BlendMode
- Works only in WebGL and may improve performance for big background images withoug alpha. The source pixels are not blended with the destination pixels and therefore the GPU does not read the color from the destination pixels.
- NORMAL → const BlendMode
- The display object appears in front of the background. Pixel values of the display object override those of the background. Where the display object is transparent, the background is visible.
- SCREEN → const BlendMode
- Multiplies the complement (inverse) of the display object color by the complement of the background color, resulting in a bleaching effect.
