关于PowerPoint的Java解决方案

心情: 一般

在找一些Java操作PPT文档的资料，得到这样一些信息：

POI(hslf)对PPT的支持还在开发之中，目前尚未发布任何版本包括测试版。可以通过apache的版本控制系统获取到正在开发中的代码，不知道能用否；
搜索引擎查到最多的是一个商业版本——TonicPoint Builder （http://tonicsystems.com/products/builder/），提供DEMO版，等填完资料后告诉你说两天后答复你；
使用jawin(http://jawinproject.sourceforge.net/)，这是一个开源的项目，只是它的工作原理是利用JNI调用OLE来操控PowerPoint，因此要求机器必须是Windows系统，且要装有PowerPoint，不是纯java的解决方案。
Here's the code to load and export a PowerPoint presentation (with strPowerPoint as the path to the PowerPoint presentation and strOutputDir as the path to a directory in which to dump the images):
```
Ole32.CoInitialize();
DispatchPtr app = new DispatchPtr("PowerPoint.Application");
DispatchPtr preses = app.getObject("Presentations");
DispatchPtr pres = (DispatchPtr) preses.invoke("open", strPowerPoint,
                                               new Integer(0), new Integer(0),
                                               Boolean.FALSE);
pres.invoke("Export", strOutputDir, "PNG");
pres.invoke("Close");
app.invoke("Quit");			
Ole32.CoUninitialize();
```
The code was based on a Jawin example. Obviously, this would be really painful for any significant amount of COM interaction, but for a quick-and-dirty task like this, it's pretty sweet.

继续搜寻中......或者等TonicPoint Builder把demo版发过来看能否破解之。如果不行，最后一种应该是最合适的方案。
