Class SVGComposite.OverCompositeContext_INT_PACK_UNPRE

java.lang.Object

org.apache.batik.ext.awt.image.SVGComposite.AlphaPreCompositeContext

org.apache.batik.ext.awt.image.SVGComposite.AlphaPreCompositeContext_INT_PACK

org.apache.batik.ext.awt.image.SVGComposite.OverCompositeContext_INT_PACK_UNPRE

All Implemented Interfaces:

CompositeContext

Enclosing class:

SVGComposite

public static class SVGComposite.OverCompositeContext_INT_PACK_UNPRE
extends SVGComposite.AlphaPreCompositeContext_INT_PACK

This implements SRC_OVER for Int packed data where the src is unpremultiplied. This avoids having to multiply the alpha on the the source then divide it out again.
