Method Detail

draw

public void draw(java.awt.Graphics2D graphics,
                 java.lang.String str,
                 int x,
                 int y)

Description copied from interface: TextRenderer.RenderDelegate

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.

Specified by:

draw in interface TextRenderer.RenderDelegate

Parameters:

graphics - the graphics instance.

str - the string to draw.

x - the x coordinate at which to draw.

y - the y coordinate at which to draw.

drawGlyphVector

public void drawGlyphVector(java.awt.Graphics2D graphics,
                            java.awt.font.GlyphVector str,
                            int x,
                            int y)

Description copied from interface: TextRenderer.RenderDelegate

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.

Specified by:

drawGlyphVector in interface TextRenderer.RenderDelegate

Parameters:

graphics - the graphics instance.

str - the GlyphVector string to draw.

x - the x coordinate at which to draw.

y - the y coordinate at which to draw.

getBounds

public java.awt.geom.Rectangle2D getBounds(java.lang.CharSequence str,

                                           java.awt.font.FontRenderContext frc)

Description copied from interface: TextRenderer.RenderDelegate

Specified by:

getBounds in interface TextRenderer.RenderDelegate

Parameters:

Returns:

the bounds of the string.

getBounds

Description copied from interface: TextRenderer.RenderDelegate

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

Specified by:

Returns:

the bounding rectangle.
