[Qgis-user] question on Ftools - polygon centroids

[Carson Farmer]

Hi Fafner,
> I have a question on the ftool-plugin, and more specifically the geometry tool "polygon centroids". I find this tool very useful. However, when I use it, quite regularly a few points get the X or Y (or both) coordinates transformed to negative numbers, instead of x = "1234567" I get x = "-1234567".

This is a known bug, and it will be fixed in a future version of fTools, 
however, no simple fix (that I know of) exists yet. It likely only 
happens with certain projections... I'll try to come up with a temporary 
fix in the mean time...

Sorry for the inconvenience,

Carson
