Package com.github.weisj.jsvg.nodes.filter

Class AbstractBlendComposite

java.lang.Object

com.github.weisj.jsvg.nodes.filter.AbstractBlendComposite

All Implemented Interfaces:

java.awt.Composite

Direct Known Subclasses:

BlendModeComposite, CompositeModeComposite.ArithmeticComposite, CompositeModeComposite.LighterComposite

public abstract class AbstractBlendComposite
extends java.lang.Object
implements java.awt.Composite

A blend composite defines the rule according to which a drawing primitive (known as the source) is mixed with existing graphics (know as the destination.)

BlendComposite is an implementation of the Composite interface and must therefore be set as a state on a Graphics2D surface.

Please refer to Graphics2D.setComposite(java.awt.Composite) for more information on how to use this class with a graphics surface.

Blending Modes

This class offers a certain number of blending modes, or compositing rules. These rules are inspired from graphics editing software packages, like Adobe Photoshop or The GIMP.

Given the wide variety of implemented blending modes and the difficulty to describe them with words, please refer to those tools to visually see the result of these blending modes.
