  No, the labels are translated to the left (so approaching to the
center of the patch), but the rest of the layout it's getting worse.

  i can't live without patchlabel, so i've no interest in investigating
further (and probably neither the programming skill). Anyway i think
that a solution will be to calculate the centroid of the patch and use
it as a center for the label.

Thanks for explaining and four your hints!
