之前也用过其他的一些方式,比如调工具。但那只能转部分格式
还用过Adobe Acrobat 8 Professional,但用java代码转格式的时候,这个软件会打开,造成速率较慢
?
最终的解决方案,放弃一切其他工具和软件,只用office自带的功能实现word,ppt,excel到pdf的转变
PS.你的office必须是07及以上,并且需要在文件另存为选项中有,“另存为pdf或XPS”?的一项
如果没有,你需要下载office相应插件SaveAsPDFandXPS
?
这里有个疑问,想问下大牛,希望大牛们不吝赐教,哞~~
安装完插件后在word的帮助里面,选搜索→点脱机开发人员帮助
再点 Word 2007 开发人员参考→新增内容→新的成员和常量→WdSaveFormat →wdFormatPDF 同样 在ppt里面,我也找得到对象ppt到pdf的常量 但在excel里面找了很长时间都没找到,?既然excel的文件另存为那里有“另存为pdf”,那就应该有这个常量啊。请大神们赐教啊 工程必备文件需要jar包
jacob.jar
?
需要dll文件(放在system32下)
jacob-1.15-M4-x86.dll
?

好了,准备工作做完,废话不多说,我们代码揍起来

??代码里面,命名很清楚,word2pdf,ppt2pdf,excel2pdf,不用解释是什么意思吧
??按需求,大家各取所需。
