I'm finding a PowerPoint library to copy, insert, delete, update and etc& slides of PowerPoint file. But I don't know what the best is. I tried use POI3.2 but its still have many bugs. I tried latest ASPOSE.Slide for java, it seem good library. But when I add Effect into slide, ASPOSE clone slide just work with entrance Effect type and lose Effect with the other.
My question: Is ASPOSE the best for me? (If no) What library should I choose?
Another question: Have a PowerPoint java library support .pptx(PowerPoint 2007) currently?
