Re: [libreoffice-users] Re: Impress - mass photo import - mass slideshow merge

HI :)
It might be better to find another OpenSource program to create your presentation.  Impress is not 
particularly brilliant but neither is PowerPoint.

Tom :)

Not that I know of, unless you do it programmatically (Python, JS or
LOBasic). There might be an extension out there somewhere on the net
that lets you do this, but I don't recall having seen one.

You would need a script for that to merge the XML - even then, you would
probably encounter the image saving bug/mess : LO, which inherited its
image storing management routines from OOo, stores each image in a ODF
file as a pseudo-randomly generated sequence of characters, and then
includes a pointer to that in the XML attributes. Your script would have
to be able to extract the image from one ODP file, in all likelihood
meaning you would have to read the binary stream API to do this, store
it in memory, rename it and resave it in the new file - fun, huh ?

this via a fairly complicated script. You could try using any of the
language bindings available for your script, and Python is as good as
any other in this respect, but be warned if you want it multi-OS and
clickable, it will not be a task for the fainthearted.
