We had a requirement of converting PowerPoint slides to images and finally display them on some kiosks. We tried many open source and other available products and none of them worked properly, other than Aspose.Slides for Java. The Aspose.Slides for Java is very easy to be integrated into the existing code and the conversion is also pretty fast. It converts even the latest format of PowerPoint slides, and of course the earlier version, with ease and perfection.

The Aspose.slides also provides easy methods to modify or create rich power pint presentations with minimum lines of code.
We would highly recommend the Aspose products to others.
