vector shape: export to PDF only as pixmap, keeping original size ratio

[Friedrich W. H. Kossebau]

Hi Inge,

there are two more issues I have with the vector shape:
export to PDF (end up as pixmap, not vector image) and getting/keeping the 
original ratio.

Anyone looking into this?

If not, any proposals how to get the original image ratio from the data?

And for export to PDF, is there a flag, so on painting/rendering one knows 
what to output, the cached pixmap or the vector commands?

Cheers
Friedrich
