> The following suggestions have been taken from OFFICE-2306:
> Why is there a folder thumbnails if there can be
> only one thumbnail? Would it make sense to allow multiple sizes, in
> order for the whole spectrum of devices (from small screen devices to
> high end systems) to have a pleasing rendering? Question: Are there no
> constraints or recommendations with regards to the PNG itself, e.g.
> allow/disallow alpha layering/color spaces? Question: What about
> accessibility - is there information we can add for blind people that
> use a file browser to navigate through a large amount of ODF files?
> Where can we store this information, and are there recommendations to
> make to those making file browsers (including office applications, who
> may include this)? Question: Should we consider allowing an SVG preview
> image, if necessary with a PNG embedded? Question: Is there information
> we should store in the metadata of the PNG? Question: Some platforms
> may require other preview formats. E.g. NeoOffice currently seems to
> add a small pdf of the first page for the preview on Mac OS X. In fact,
> one could say that a low resolution version of a PDF rendering of an
> ODF file would be an interesting addition to the preview concept in ODF
> in some cases - it is a frozen, final format version. It might be
> interesting to recommend applications should be allowed to include the
> possiblity to include full PDF's in ODF as preview. That way hybrid
> PDF's are available both ways: PDF contained within ODF ('as last seen
> by the author', ODF contained within PDF ('meant as a final
> publication, but you can edit it if you want'. Of course these two
> mechanisms should not loop.
