Package org.jzy3d.plot3d.text.renderers

Class TextRenderer

java.lang.Object

org.jzy3d.plot3d.text.AbstractTextRenderer

org.jzy3d.plot3d.text.renderers.TextRenderer

All Implemented Interfaces:

ITextRenderer

Direct Known Subclasses:

AxisBox2d.RotatedTextBitmapRenderer

public class TextRenderer
extends AbstractTextRenderer
implements ITextRenderer

The ITextRenderer computes text layout according to Horizontal, Vertical settings, text length, font size and text position. This is achieved with the help of TextLayout processor. It can be given a 2D offset in screen coordinates and a 3D offset in world coordinates that are applied after the initial layout is processed according to the settings, the text length, the font size and the text position. Rendering text relies on IPainter.drawText(Font, String, Coord3d, Color, float) which was introduced as of Jzy3D 2.0 and offers much more flexibility than the initial simple IPainter.glutBitmapString(int, String) which only support two fonts.
