[Qgis-user] question on Ftools - polygon centroids
Hi, 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. Is this a known bug? Is there any way to prevent this? Can I edit the coordinates manually to fix this? I use Qgis 1.0.1_Kore in Ubuntu 8.04lts, I have also experienced the error in Qgis for Windows. The coordinate system in use is Sweref99 TM. thanx / Fafner -- View this message in context: http://n2.nabble.com/question-on-Ftools---polygon-centroids-tp2540371p2540371.html Sent from the qgis-user mailing list archive at Nabble.com. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Is there any way to prevent this? Can I edit the coordinates manually to fix this? 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 -- Carson J. Q.

Re: [Qgis-user] question on Ftools - polygon centroids
Fafner, Hi Carson thank you for the prompt reply, thanx also for your awesome work on the ftools. Your first email motivated me to come up with an interim solution (which might actually become the permanent fix) this evening. I will upload this fix to my repository tonight, and you should be able to run the centroids tool on pretty much any projection... Please test (should be version 0.5.8) and let me know if this problem is fixed. Cheers, Carson -- Carson J. Q.

Please test (should be version 0.5.8) and let me know if this problem is fixed. Hi Carson, I just upgraded to 0.5.8 and in manage plugins it now says that ftools is incompatible and so cannot be activated. regards -- Giovanni -- ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Oops, my bad, I think I deleted the minimum qgis version.. ok I'll upload in a minute... the version number won't change, but if you wait about 15 minutes you can try to download again... C ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
