2、在resources目錄下添加ISOcoated_v2_300_eci.icc文件
聲明：
此文章是給照片生成平鋪水印的照片文件，並解決javax.imageio.IIOException: Unsupported Image Type異常，
javax.imageio.IIOException: Unsupported Image Type異常的產生原因是因爲圖片的顏色模式具體錯誤描述請看另一篇文章
點擊跳轉：javax.imageio.IIOException: Unsupported Image Type異常詳解
此文章僅發佈成功生產平鋪水印無異常的照片文件
操作：
1、第一步引入pom文件
本身生產水印圖片的方法不用引入pom文件，僅僅使用java.awt包即可，但是這裏是解決異常問題，所以添加了其他pom文件解決問題
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-imaging</artifactId>
<version>1.0-alpha1</version>
</dependency>
<dependency>
<groupId>org.apache.sanselan</groupId>
<artifactId>sanselan</artifactId>
<version>0.97-incubator</version>
</dependency>
2、在resources目錄下添加ISOcoated_v2_300_eci.icc文件
ISOcoated_v2_300_eci.icc此文件爲解決顏色轉碼失去準確性的文件，也是爲了解決異常問題
3、添加工具文件生成水印圖片類

4、測試結果
如果想讓水印旋轉可以修改ImageByText (logoText, srcImg, targerPath, -10);參數 -10代表旋轉角度，可自行調試
結束！感謝觀看～
