gitee项目地址:/betelnutandwine/meutilswatermark: java实现pdf,word,excel,ppt,图片加水印
jar地址:spire.office.free-5.3.1.jar-Java文档类资源-CSDN下载
spire.office.free官方地址:Spire.Office for Java ｜ 专业的 Java Office 套件 ｜ 创建、修改、转换、打印 Word/PowerPoint/PDF 文档
说明:
基于spire.office.free-5.3.1.jar实现的.
由于是免费版,会有一些官方的水印,ppt,pdf加水印限制为10页
excel的水印在打印的时候再能看到,或者点击页面布局打印预览也可看到
图片加水印不需要spire.office.free-5.3.1.jar支持
gitee上的项目不是maven,可能需要手动导下包
