Modifier and Type	Method	Description
void	draw(java.awt.Graphics2D graphics, java.lang.String str, int x, int y)	* Render the passed character sequence at the designated location using the supplied Graphics2D instance.The surrounding region will already have been cleared to the RGB color (0, 0, 0) with zero alpha.The initial drawing context of the passed Graphics2D will be set to use AlphaComposite.Src, the color white, the Font specified in the TextRenderer's constructor, and the rendering hints specified in the TextRenderer constructor.Changes made by the end user may be visible in successive calls to this method, but are not guaranteed to be preserved.Implementors of this method should reset the Graphics2D's state to that desired each time this method is called, in particular those states which are not the defaults.
void	drawGlyphVector(java.awt.Graphics2D graphics, java.awt.font.GlyphVector str, int x, int y)	* Render the passed GlyphVector at the designated location using the supplied Graphics2D instance.The surrounding region will already have been cleared to the RGB color (0, 0, 0) with zero alpha.The initial drawing context of the passed Graphics2D will be set to use AlphaComposite.Src, the color white, the Font specified in the TextRenderer's constructor, and the rendering hints specified in the TextRenderer constructor.Changes made by the end user may be visible in successive calls to this method, but are not guaranteed to be preserved.Implementors of this method should reset the Graphics2D's state to that desired each time this method is called, in particular those states which are not the defaults.
java.awt.geom.Rectangle2D	getBounds(java.awt.font.GlyphVector gv, java.awt.font.FontRenderContext frc)	Computes the bounds of the given GlyphVector, already assumed to have been created for a particular Font, relative to the origin.
java.awt.geom.Rectangle2D	getBounds(java.lang.CharSequence str, java.awt.Font font, java.awt.font.FontRenderContext frc)	Computes the bounds of the given character sequence relative to the origin.
java.awt.geom.Rectangle2D	getBounds(java.lang.String str, java.awt.Font font, java.awt.font.FontRenderContext frc)	Computes the bounds of the given String relative to the origin.
boolean	intensityOnly()	Indicates whether the backing store of this TextRenderer should be intensity-only (the default) or full-color.
