Issues with Powerpoint OLE Objects

[omsoft]

I use Docsplit to extract images from PPTs: it works great, but some graphs linked inside the original Powerpoint are not visible. There is a small "OLE" thumbnail in place of them.

Is there a way to import those graphs, too?

Thanks

Hey @omsoft, do you have any sample files you might be able to share with us?

For sure, here it is. I've tried to use the original PPTx or PPT 97/2003. In either cases those graphs are not visible.
Take a look at slide nr.24

Let me know ;)
thanks a lot
