Field Detail

### NUM_KERNELS

    public static final int NUM_KERNELS

  The number of kernels to apply

  See Also:
    Constant Field Values

### GAUSSIAN_BLUR_KERNELS

    public static final float[][] GAUSSIAN_BLUR_KERNELS

  The blur kernels applied across the effect

Constructor Detail

### ShadowEffect

    public ShadowEffect()

  Default constructor for injection

### ShadowEffect

    public ShadowEffect(java.awt.Color color,
                        int xDistance,
                        int yDistance,
                        float opacity)

  Create a new effect to apply a drop shadow to text

  Parameters:
    `color` - The colour of the shadow to generate
    `xDistance` - The distance from the text on the x axis the shadow should be rendered
    `yDistance` - The distance from the text on the y axis the shadow should be rendered
    `opacity` - The transparency factor of the shadow

Method Detail

### draw

    public void draw(java.awt.image.BufferedImage image,
                     java.awt.Graphics2D g,
                     UnicodeFont unicodeFont,
                     Glyph glyph)

  Description copied from interface: `Effect`
  Called to draw the effect.

  Specified by:
    `draw` in interface `Effect`
  Parameters:
    `image` - The image to draw into
    `g` - The graphics context to use for applying the effect
    `unicodeFont` - The font being rendered
    `glyph` - The particular glyph being rendered
  See Also:
    `Effect.draw(java.awt.image.BufferedImage, java.awt.Graphics2D, org.newdawn.slick.UnicodeFont, org.newdawn.slick.font.Glyph)`

### getColor

    public java.awt.Color getColor()

  Get the colour of the shadow generated

  Returns:
    The colour of the shadow generated

### setColor

    public void setColor(java.awt.Color color)

  Set the colour of the shadow to be generated

  Parameters:
    `color` - The colour ofthe shadow to be generated

### getXDistance

    public float getXDistance()

  Get the distance on the X axis from the text the shadow should be generated at

  Returns:
    The distance on the X axis the shadow will be from the text

### setXDistance

    public void setXDistance(float distance)

  Sets the pixels to offset the shadow on the x axis. The glyphs will need padding so the shadow doesn't get clipped.

  Parameters:
    `distance` - The offset on the x axis

### getYDistance

    public float getYDistance()

  Get the distance on the Y axis from the text the shadow should be generated at

  Returns:
    The distance on the Y axis the shadow will be from the text

### setYDistance

    public void setYDistance(float distance)

  Sets the pixels to offset the shadow on the y axis. The glyphs will need padding so the shadow doesn't get clipped.

  Parameters:
    `distance` - The offset on the y axis

### getBlurKernelSize

    public int getBlurKernelSize()

  Get the size of the kernel used to apply the blur

  Returns:
    The blur kernel size

### setBlurKernelSize

    public void setBlurKernelSize(int blurKernelSize)

  Sets how many neighboring pixels are used to blur the shadow. Set to 0 for no blur.

  Parameters:
    `blurKernelSize` - The size of the kernel to apply the blur with

### getBlurPasses

    public int getBlurPasses()

  Get the number of passes to apply the kernel for blurring

  Returns:
    The number of passes

### setBlurPasses

    public void setBlurPasses(int blurPasses)

  Sets the number of times to apply a blur to the shadow. Set to 0 for no blur.

  Parameters:
    `blurPasses` - The number of passes to apply when blurring

### getOpacity

    public float getOpacity()

  Get the opacity of the shadow, i.e. how transparent it is

  Returns:
    The opacity of the shadow

### setOpacity

    public void setOpacity(float opacity)

  Set the opacity of the shadow, i.e. how transparent it is

  Parameters:
    `opacity` - The opacity of the shadow

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
  See Also:
    `Object.toString()`

### getValues

    public java.util.List getValues()

  Description copied from interface: `ConfigurableEffect`
  Returns the list of `ConfigurableEffect.Value`s for this effect. This list is not typically backed by the effect, so changes to the values will not take affect until `ConfigurableEffect.setValues(List)` is called.

  Specified by:
    `getValues` in interface `ConfigurableEffect`
  See Also:
    `ConfigurableEffect.getValues()`

### setValues

    public void setValues(java.util.List values)

  Description copied from interface: `ConfigurableEffect`
  Sets the list of `ConfigurableEffect.Value`s for this effect.

  Specified by:
    `setValues` in interface `ConfigurableEffect`
  See Also:
    `ConfigurableEffect.setValues(java.util.List)`
