jmagic添加中文乱码问题

Question

如题MagickImage image;
        String srcImage="d:/1.jpg";
        String icon="d:/2.jpg";
        ImageInfo info=new ImageInfo(srcImage);
        ImageInfo info2=new ImageInfo(icon);
        
        image=new MagickImage(info);
        MagickImage iconImage=new MagickImage(info2);
        //System.out.println(image.getXResolution()+"       "+image.getYResolution());
        MagickCanvas canvas=new MagickCanvas();
        canvas.setImage(image);
        DrawInfo aInfo=new DrawInfo(new ImageInfo());
        
//        aInfo.setTile(image);
        aInfo.setFill(PixelPacket.queryColorDatabase("red"));
        aInfo.setOpacity(50);
        aInfo.setPointsize(40);
//        aInfo.setFont("fixed");
        aInfo.setText(toGb("Hello,中国"));
        aInfo.setTextAntialias(true);
        aInfo.setGeometry("+100+200");
        
//        image.compositeImage(3,iconImage,canvas.getWidth()/2-80,canvas.getHeight()/2-100);
        
        image.annotateImage(aInfo);
        
        
        MagickImage imageResize=image;
        imageResize.setFileName("d:/1_1.jpg");
       
        imageResize.writeImage(info);    public static String toGb(String uniStr){
        String gbStr = uniStr;
        if(uniStr == null){
        uniStr = "";
        }
        try{
        byte[] tempByte = uniStr.getBytes();
        gbStr=new String(tempByte,"ISO8859_1");
        }catch(Exception ex){
        }
        return gbStr;
    }以上是我对两个图片合成后添加了文字，但图片上面显示的是乱码。在控制台里面输出时已经显示是正确的中文，为何图片上面还是乱码呢，请哪位使用过的帮我一下。在线等
