Class JLabelJ3D

java.lang.Object
  visad.bom.annotations.JLabelJ3D

All Implemented Interfaces:

ScreenAnnotation

public class JLabelJ3D
extends Object
implements ScreenAnnotation

Meant to encapsulate information representing a label which is going to be rendered on a VisAD display without being subject to the usual VisAD transformations. Thus the label should stick in Screen Coordinates. It should render using the Java3D Text3D class. Java3D dependent only in needing Text3D.

Constructor Summary

JLabelJ3D(String text)
It constructs a JLabelJ3D with text at the origin, coloured white.

JLabelJ3D(String text, int xLocation, int yLocation, float[] colour, Font font, double zValue, double fontSizeInPixels, int align, int path)
Constructor for a JLabel3D - It is filled and should have non null Font.

Method Summary

void	setAlign(int align)
void	setColour(float[] colour)
void	setFont(Font font)
void	setFontSize(double fontSizeInPixels)
void	setLocation(int xLocation, int yLocation)
void	setPath(int path)
void	setText(String text)
void	setZValue(double zValue)
