createContext in interface Composite

getAlpha

public float getAlpha()

Returns the alpha value of this BlendComposite.

Returns:

the alpha value of this BlendComposite.

getBlend

public BlendComposite.BlendingMode getBlend()

Returns the blend of this BlendComposite.

Returns:

the blend of this BlendComposite.

geteInstance

public static Composite geteInstance(BlendComposite.BlendingMode mode)
