Constructor Detail

GlyphRenderer

public GlyphRenderer(java.lang.String text,
                     AnimationFunction<java.lang.Float> scaleFunction,
                     AnimationFunction<java.lang.Float> translateFunction,
                     AnimationFunction<java.awt.Color> colorFunction,
                     long glyphDelay)

Constructs a GlyphRenderer that paints individual glyphs with different transforms.

Parameters:

text - the initial text

scaleFunction - maps times to glyph scales

translateFunction - maps times to glyph translations

colorFunction - maps times to colors

glyphDelay - a time delay between the glyph animations

Method Detail

getTime

public long getTime()

setTime

public void setTime(long time)

relativeTime

private long relativeTime(int glyphIndex)

scaleAt

private float scaleAt(int glyphIndex)

colorAt

private java.awt.Color colorAt(int glyphIndex)

render

public void render(java.awt.Graphics2D g2,
                   int width,
                   int height)

Renders the text. Firstly, ensures a valid cache, then sets the color, and finally paints the cached glyph shaped, using individual transforms.

Parameters:

g2 - the graphics object to render on

width - the width of the graphics area

height - the height of the graphics area
