示例1: filter

@Override
public BufferedImage filter(BufferedImage src, BufferedImage dst) {
if(blurMethod == FAST_BLUR) {
dst = new FastBlurFilter((int) radius).filter(src, null);
} else if (blurMethod == BOX3_BLUR) {
if ((src.getWidth() == 1) || (src.getHeight() == 1)) {
// otherwise we get ArrayIndexOutOfBoundsException in BoxBlurFilter
return src;
}
dst = new BoxBlurFilter(radius, radius, 3).filter(src, null);
} else if(blurMethod == GAUSSIAN_BLUR) {
dst = new GaussianFilter(radius).filter(src, null);
