Premult
Brief Description
Multiply the Red, Green and Blue channels of the image by its alpha channel. Using this modifier is rarely needed as alpha premultiplication is automatically handled by Autograph. However in certain cases where for example you inject a custom alpha with a Shuffle Modifier, you may need to apply this modifier manually.
