[svagg-users] perspective transformations

[<vla...@gm...>]

Hi all,

I am having a small problem with perspective transformations. If I
transform larger images (64x64 pixels and more), all works fine, but
if I try to transform small ones, like 16x16 pixels, the results are
quite weird. The outline of the transformed rectangle consist of
curves(!), not lines anymore, and even the corners are misplaced.

Could it be that there is a loss of precision due to underflow or
something like that in agg's perspective transformation? Or should I
keep looking in my own code?

Thanks for any suggestions,
Vlasta
