本文主要是介绍java 图片转换、加水印等工具类，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
技术实现：主要使用的jmagick.jar 和jdk本身自带的图像处理jar
主要方法：
1.获取图片信息
2.压缩图片
3.水印(文字)
4.切图
5.按照指定的宽高进行图片缩放
6.图片按照等比缩放
7.图片缩放
8.图片按照等比缩放
9.给图片添加文字水印
10.给图片添加水印、可设置水印的旋转角度,并调整大小
11.根据文字生成图片
12.将多个小图片合成一张大jpg图 (小的jpg图片按照行列顺序平铺)
13.彩色转为黑白
14. 添加图片水印---指定图片水印的4个位子(0,1,2,3,4,5)
15.图片加文字文字(五个位置，分别是图片的左上角，右上角，中间，左下角，右下角）对应参数 int weizhi 可以取0到4)
16.通过 ImageMagick 的 convert 转换成实现psd文件转换成其他图片
17.取得汉字的长度
安装步骤：
jar包地址 http://downloads.jmagick.org/6.3.9/
* window下使用的是: jmagick-win-6.3.9-Q16.zip 和 ImageMagick-6.3.9-0-Q16-windows-dll.exe

* 六. ln -s /usr/local/imgtools/JMagick/lib/libJMagick.so /usr/lib/libJMagick.so
* 不做这步会报一个找不到lib.path的错误
* 七.java代码使用一下包
* /usr/local/imgtools/JMagick/lib/jmagick.jar3.代码集，我们没有整理，直接复制的java类，请自己挑选自己用的上的方法。
