[scribus] background pattern fill

[vwf]

Hello,

This may be not a real Scribus question, but maybe someone has the
answer. I want to use a small part of a photo as a background colour: a
pattern fill. Scribus cannot do that (yet)? I tried Inkscape, but that
produces an image with stripes because of a strange fill algorithm. Is
there a technique to get a solid background from a small tile of photo?

Thanks,
Frits
