extends GraphicsPrimitive
Class Inheritance
Known Direct Subclasses
sun.java2d.loops.TransformHelper.TraceTransformHelper
Imports
java.awt.Composite, java.awt.geom.AffineTransform, sun.java2d.SurfaceData, sun.java2d.pipe.Region
TransformHelper 1) applies an AffineTransform to a rectangle of pixels while copying from one surface to another 2) performs compositing of colors based upon a Composite parameter precise behavior is undefined if the source surface and the destination surface are the same surface with overlapping regions of pixels
