Hi,

I ran into some trouble with the MSOD->Karbon filter and I need some advice:

1. MSOD doesn't only have host specific data - it also requires some 
information from the host. For example, the texts of each powerpoint slide 
are stored outside the MSOD chunk, but are referenced from within it. The 
same goes for the color scheme as far as I know.
Therefore, I think host specific information needs to be passed to the 
MSOD->Karbon filter. Is it a good idea to prepend host specific data to the 
MSOD data sent to the filter? It can be packed like an ordinary MSOD 
container, with an atom identifying the host (maybe an integer that will 
equal 0 for powerpoint, 1 for ms word and 2 for excel?), and then a sub 
container with host records (in the host's format) that are relevant to the 
MSOD filter (for powerpoint these are text and color scheme records). If the 
filter can't find the host specific container it will attempt to function 
without host specific information, so it remains compatible with programs 
already using it (currently only the PPT filter). Even though this method will 
work, I'm not sure it's the right way to go, so please help me out a little.

2. If I understand correctly, Karbon describes (in its XML files) text 
characters (and strings) like it does shapes. This means I need to specify 
the character shape data myself. I could do this by making a list of 
character shapes (which I can generate with Karbon) to be scaled/rotated as 
necessary to construct strings. However, I can only do this for a limited 
number of fonts (one?). Is this an acceptable solution?

Thanks.
