如何在Java中调整图片大小？

我使用仿射变换来完成此任务，这是我的代码，希望对您有所帮助

public static BufferedImage scale(BufferedImage sbi, int imageType, int dWidth, int dHeight, double fWidth, double fHeight) {    BufferedImage dbi = null;    if(sbi != null) {        dbi = new BufferedImage(dWidth, dHeight, imageType);        Graphics2D g = dbi.createGraphics();        AffineTransform at = AffineTransform.getScaleInstance(fWidth, fHeight);        g.drawRenderedImage(sbi, at);    }    return dbi;}
