RenderContext

• java.lang.Object

Fields Summary
RenderingHints	hints Table of hints. May be null.
AffineTransform	usr2dev Transform to convert user coordinates to device coordinates.
Shape	aoi The area of interest. May be null.

Constructors Summary
public RenderContext(AffineTransform usr2dev, Shape aoi, RenderingHints hints) Constructs a RenderContext with a given transform. The area of interest is supplied as a Shape, and the rendering hints are supplied as a RenderingHints object. param usr2dev an AffineTransform. param aoi a Shape representing the area of interest. param hints a RenderingHints object containing rendering hints. this.hints = hints; this.aoi = aoi; this.usr2dev = (AffineTransform)usr2dev.clone();
public RenderContext(AffineTransform usr2dev) Constructs a RenderContext with a given transform. The area of interest is taken to be the entire renderable area. No rendering hints are used. param usr2dev an AffineTransform. this(usr2dev, null, null);
public RenderContext(AffineTransform usr2dev, RenderingHints hints) Constructs a RenderContext with a given transform and rendering hints. The area of interest is taken to be the entire renderable area. param usr2dev an AffineTransform. param hints a RenderingHints object containing rendering hints. this(usr2dev, null, hints);
public RenderContext(AffineTransform usr2dev, Shape aoi) Constructs a RenderContext with a given transform and area of interest. The area of interest is supplied as a Shape. No rendering hints are used. param usr2dev an AffineTransform. param aoi a Shape representing the area of interest. this(usr2dev, aoi, null);

Methods Summary
public java.lang.Object	clone() Makes a copy of a RenderContext. The area of interest is copied by reference. The usr2dev AffineTransform and hints are cloned, while the area of interest is copied by reference. return the new cloned RenderContext. RenderContext newRenderContext = new RenderContext(usr2dev, aoi, hints); return newRenderContext;
public void	concatenateTransform(java.awt.geom.AffineTransform modTransform) Modifies the current user-to-device transform by appending another transform. In matrix notation the operation is: [this] = [this] x [modTransform] param modTransform the AffineTransform to append to the current usr2dev transform. this.concetenateTransform(modTransform);
public void	concetenateTransform(java.awt.geom.AffineTransform modTransform) Modifies the current user-to-device transform by appending another transform. In matrix notation the operation is: [this] = [this] x [modTransform] This method does the same thing as the concatenateTransform method. It is here for backward compatibility with previous releases which misspelled the method name. param modTransform the AffineTransform to append to the current usr2dev transform. deprecated replaced by concatenateTransform(AffineTransform). usr2dev.concatenate(modTransform);
public java.awt.Shape	getAreaOfInterest() Gets the ares of interest currently contained in the RenderContext. return a reference to the area of interest of the RenderContext, or null if none is specified. see #setAreaOfInterest(Shape) return aoi;
public java.awt.RenderingHints	getRenderingHints() Gets the rendering hints of this RenderContext. return a RenderingHints object that represents the rendering hints of this RenderContext. see #setRenderingHints(RenderingHints) return hints;
public java.awt.geom.AffineTransform	getTransform() Gets the current user-to-device AffineTransform. return a reference to the current AffineTransform. see #setTransform(AffineTransform) return (AffineTransform)usr2dev.clone();
public void	preConcatenateTransform(java.awt.geom.AffineTransform modTransform) Modifies the current user-to-device transform by prepending another transform. In matrix notation the operation is: [this] = [modTransform] x [this] param modTransform the AffineTransform to prepend to the current usr2dev transform. this.preConcetenateTransform(modTransform);
public void	preConcetenateTransform(java.awt.geom.AffineTransform modTransform) Modifies the current user-to-device transform by prepending another transform. In matrix notation the operation is: [this] = [modTransform] x [this] This method does the same thing as the preConcatenateTransform method. It is here for backward compatibility with previous releases which misspelled the method name. param modTransform the AffineTransform to prepend to the current usr2dev transform. deprecated replaced by preConcatenateTransform(AffineTransform). usr2dev.preConcatenate(modTransform);
public void	setAreaOfInterest(java.awt.Shape newAoi) Sets the current area of interest. The old area is discarded. param newAoi The new area of interest. see #getAreaOfInterest aoi = newAoi;
public void	setRenderingHints(java.awt.RenderingHints hints) Sets the rendering hints of this RenderContext. param hints a RenderingHints object that represents the rendering hints to assign to this RenderContext. see #getRenderingHints this.hints = hints;
public void	setTransform(java.awt.geom.AffineTransform newTransform) Sets the current user-to-device AffineTransform contained in the RenderContext to a given transform. param newTransform the new AffineTransform. see #getTransform usr2dev = (AffineTransform)newTransform.clone();
