Many thank for you all guys, based on your advice, I think I'm approching the solution.
Actually we have setup a Flash RIA based website, http://www.weekee.tv/liveboard. This site is setup for e-Learning and web conference based on PPT and other resources, such as video\audio\images. People can upload ppt format document onto the website, and we have written a CODEC backend to convert these files into our formats. And, after uploading, people can drag the ppt onto a shared whiteboard and begin talking and marking, the system will record all the process, and finally generate a courseware which can be viewed on the internet. This is a demo courseware<http://www.weekee.tv/liveboard/player.swf?course=ca0f863b-0120-4a60-b4cf-a875015b813b>we recorded, unfortunatedly it is in Chinese. In this CODEC server, we first use JOD-Converter to transform PPT to zip file, and then we extract the zip file into many seperate pieces of resources, e.g, images, objects, and we will translate content.xml and styles.xml into a xml of our format. Based on this xml, the flash client can play these PPT and resources. The reason why I posted this question is that we found we can't transform the objects just by ourselves. But according to your replies, we found that OO provides us many useful services that we can directly leverage on. I believe that PPT to Flash convertation is quite useful, because flash player is the most popular web plugins in the world, across OSes and across explorers. And ODF is a world standard so that our job is sure on the basis of it. We will keep on the paces of OO's development, and try our best to contribute to the community. Thanks for your help again. After the problem is solved, I will post some source codes so that you guys can help me check it.
