文字不清晰，K图也断断续续的了。这里icech找到一个缩小图片不失真的代码，还是不错的，测试成功！针对GIF和JPG的图片效果不错。
代码如下：
Java代码
- public static void reduceImg(String imgsrc, String imgdist, int widthdist,
- int heightdist) {
- try {
- File srcfile = new File(imgsrc);
- if (!srcfile.exists()) {
- return;
- }
- Image src = javax.imageio.ImageIO.read(srcfile);
- BufferedImage tag= new BufferedImage((int) widthdist, (int) heightdist,
- BufferedImage.TYPE_INT_RGB);
- tag.getGraphics().drawImage(src.getScaledInstance(widthdist, heightdist, Image.SCALE_SMOOTH), 0, 0, null);
- // tag.getGraphics().drawImage(src.getScaledInstance(widthdist, heightdist, Image.SCALE_AREA_AVERAGING), 0, 0, null);
- FileOutputStream out = new FileOutputStream(imgdist);
- JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
- encoder.encode(tag);
- out.close();
- } catch (IOException ex) {
- ex.printStackTrace();
- }
- }
