Interface TextRenderer.RenderDelegate
- All Known Implementing Classes:
TextRenderer.DefaultRenderDelegate
- Enclosing class:
- TextRenderer
public static interface TextRenderer.RenderDelegate
Class supporting more full control over the process of rendering
the bitmapped text. Allows customization of whether the backing
store text bitmap is full-color or intensity only, the size of
each individual rendered text rectangle, and the contents of
each individual rendered text string. The default implementation
of this interface uses an intensity-only texture, a
closely-cropped rectangle around the text, and renders text
using the color white, which is modulated by the set color
during the rendering process.

Method Summary
Modifier and TypeMethodDescriptionvoid
draw
(Graphics2D graphics, String str, int x, int y) Render the passed character sequence at the designated location using the supplied Graphics2D instance.void
drawGlyphVector
(Graphics2D graphics, GlyphVector str, int x, int y) Render the passed GlyphVector at the designated location using the supplied Graphics2D instance.getBounds
(GlyphVector gv, FontRenderContext frc) Computes the bounds of the given GlyphVector, already assumed to have been created for a particular Font, relative to the origin.getBounds
(CharSequence str, Font font, FontRenderContext frc) Computes the bounds of the given character sequence relative to the origin.getBounds
(String str, Font font, FontRenderContext frc) Computes the bounds of the given String relative to the origin.boolean
Indicates whether the backing store of this TextRenderer should be intensity-only (the default) or full-color.

intensityOnly
boolean intensityOnly()Indicates whether the backing store of this TextRenderer should be intensity-only (the default) or full-color. -
getBounds
Computes the bounds of the given String relative to the origin. -
getBounds
Computes the bounds of the given character sequence relative to the origin. -

Computes the bounds of the given GlyphVector, already assumed to have been created for a particular Font, relative to the origin. -
draw
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. -
