Good day! I am currently having a problem with the preview generation of powerpoint documents
There are 6 ppt presentations and only one presentation(800kb) is working fine. All other ppt are not generating a preview (approx.1.1-5.9MB). Is this because of the file size? I have set max.file.size to 50 MB.

This is the error log:

Good day! I am having a trouble in previewing ppt presentations.
In windows xp os, when I tried to upload a document in openkm, preview doesnt work. when i tried to download that document in openkm, it gives 0 byte size and blank presentation.
Now, I created a shared folder with my linux from windows. I have uploaded the same document/ppt presentations and now it works fine.
Can someone explain to me what happened? How can other users (especially when their os is XP) upload documents properly?

PostPosted:**Fri Jun 24, 2011 6:36 pm**

1- Which openkm version are you using, and which openoffice version ( on windows is diferent than linux ? ) ?
2- Can you convert the file directly with openoffice ?
3- Can you export a word document to pdf, that's good test to ensure openoffice service has been right started by openKM ?

PostPosted:**Thu Jun 30, 2011 12:43 am**

Hello! sorry for the late reply..
I've been using OpenKM 5.1.5 in linux and OpenOffice 3.1.1
In my linux server, I can convert directly the files in any pdf & vice versa.
However when I tried to upload a document from windows to OpenKM, preview is not working.
I've been using flexpaper as my previewer and it shows on the right hand corner "Infinity"
What might have caused the problem?

PostPosted:**Sat Jul 02, 2011 1:13 pm**

I suggest upgrade to 5.1.6 ( it's easy )
On Which operating system do you have OpenKM installed ( the server ) ?

1- Ensure you can convert .doc to pdf ( into OpenKM )
2- Then try with small power point
3- After it try with bigger

PostPosted:**Mon Jul 04, 2011 5:37 pm**

Can you reproduce the problem in the online demo? http://demo.openkm.com

Al try to open the document with your installed OpenOffice. I think that OpenOffice version is quite old and can't handle PPTX documents.

PostPosted:**Thu Jul 28, 2011 5:51 am**

Good day sir! I have done the following steps still the problem persists: SOME of the ppt presentations are still not previewing.
1. I have migrated from OpenkM 5.1.5 to 5.1.7
2. I removed the Openoffice 3.0.1 version and installed the latest version 3.3
3. I have pdf2swf and Imagemagick working.

this is the error I am getting:

Hi

what i learned from my "not previewing session" is to clear the pdf cache (openkm/cache/pdf)
If there is a document with a converting error , the error will not be solved automatically

After cleaning up the cache, openkm will generate a new preview using the new setup

Please look in the PDF cache folder if a readable PDF is generated.
If so, OpenKM and OpenOffice are working together

Also, in a few other posts jllort and pavilla are mentioning that the newest version of openoffice (3.3) is not the most reliable choice at this moment
OpenOffice 3.1 or 3.2 are the stable choices for OpenKM at this moment

PostPosted:**Mon Aug 08, 2011 8:02 pm**

In next stable OpenKM 5.1.8 release the document conversion logic has been improved. I don't know when will be released, but you can grab a night build from http://integration.openkm.com/5.1.x/ .
