Method Detail

createShadow

public static java.awt.image.BufferedImage createShadow(java.awt.Image src,
                                                        java.awt.Paint shadowPaint,
                                                        int blurRadius)

Create and return a new buffered image containing a shadow of the specified source image using the specifed shadow paint and gaussian blur radius. The dimensions of the returned image will be src.getWidth() + 4 * blurRadius x src.getHeight() + 4 * blurRadius to account for blurring beyond the bounds of the source image. Thus the source image will appear to be be offset by (2 * blurRadius, 2 * blurRadius) in the returned image.

Parameters:

src - source image, must not be null

shadowPaint - shadow paint

blurRadius - gaussian blur radius, must be > 0

Returns:

a new buffered image containing a shadow of the specified source image using the specifed shadow paint and gaussian blur radius
