Java给ceb文件添加水印

通过设置页面，点击添加水印即可

通过设置页面，点击添加水印就可以，或则到“控制面板”-“打印机和传真”里面，把“adobe PDF”打印机改名为“PDF”，就可以打印成pdf了。

最近项目在做一个商城项目 项目上的图片要添加水印① 添加图片水印②:添加文字水印一下提供下个方法 希望大家可以用得着   复制代码 代码如下: package blogs imageimport java awt AlphaCompositeimport java awt Colorimport java awt Fontimport java awt Graphics Dimport java
