Re: Powerpoint and HSLF
Hi Nick, Thanks for the answers... These are my futher findings: - Slide ID is really in the Slide Persist Atom unless the slide is from the Template - The slide sequence is listed under the latest 1000 record under 4080 and the sequence of 1011 shows the list slides ... There is no real Slide number that I can find. I am using Powerpoint 2002 SP3 Thanks Regards, Budi Darmawan ITSO Tivoli Projects [EMAIL PROTECTED] phone: 1-512-838-7184 Sunday, March 26, 2006 3:27 PM To: POI Users List poi-user@jakarta.apache.org cc: From: Nick Burch [EMAIL PROTECTED] Subject: Re: Powerpoint and HSLF On Fri, 24 Mar 2006, Budi Darmawan wrote: I am trying to extract slides information from PPT files using POI HSLF (alpha 3.0 scratchpad).

There is no real Slide number that I can find. Yup, you just seem to have to get the slide number from either the RefId or the Identifier. I'm wondering if the RefId can be used to identify the slide record, but I've yet to test this out on a document with lots of slides. Any chance you could upload one of your out-of-order PPT docs to bugzilla, so I can use it to check if I ever fix the out-of-order stuff?

I'm wondering if the RefId can be used to identify the slide record, but I've yet to test this out on a document with lots of slides. I'm starting to think that the RefId in a SlidePersistAtom corresponds to the ID of a core record (as found from PersistPtr stuff). So, you find a SlidePersistPtr. That gives you the slide's external facing ID (via SlideIdentifier), which is also the value used to match a Slide to its Notes (SlideAtom - Notes ID, NotesAtom - Slide ID). Then, you take the RefId, and go and fetch the record that has that ID allocated to it by the PersistPtr stuff (in hslf, that means the most recent core record with an ID one less than that, since our array is zero based). That should be the matching slide record. (With slides with notes, this does all tie up). Can you run org.apache.poi.hslf.dev.SlideIdListing against a problem sheet, and check that the RefIds from SlidePersistAtom matches that sheet ID from PersistPtr? If it does, I can use the above to link slides and their text better, hopefully fixing your out-of-order problem Nick - To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/
Re: Powerpoint and HSLF
Yes, the output from Slide ID listing quite match with it.
