Have there been any updates on this? I also need to be able to simply report save progress. Aspose Cells allows me to do this with its IPageSavingCallback handle. Like the original poster of this question, I want the normal PDF containing all of the pages but I need to monitor the “Page X of Y Saved” progress. That is, I don’t want to mess with the stream at all and I don’t need individual pages saved separately. I just need to know how far along the conversion is.
