Re: [mapserver-users] Rewarping/Reprojection with GDAL and -wo EXTRA_SOURCE parameter
Have you set the PROCESSING directive at the grid layer? With the patch applied, adding PROCESSING FORCE_FULL_EXTENT=YES at the GRID layer fixed it for me, ie: LAYER TYPE LINE STATUS DEFAULT EXTENT -180 -90 180 90 NAME GRID OPACITY 50 # the following line enables the hack: PROCESSING FORCE_FULL_EXTENT=YES I used the BBOXes from your examples below to generate the attached images. The POSTGIS (i.e. POLYGON) and RASTER layers are fine in any zoom or pan level. The LINE layer is ok if the BBOX has not been paned to far of center (for the ortho projection) and if extremly zoomed in the poles are cut. It looks like that POLYGON and LINE Layers are treated a little bit differently. If you like here is the test site with the patch included.

Re: [mapserver-users] Rewarping/Reprojection with GDAL and -wo EXTRA_SOURCE parameter
Oh Andreas, blind me. Copied it into the POSTGIS layer but not the LINE Layer. Sorry for that. It works now as described, panning and zooming is ok. Btw, where to send the bugreport ? Thanks and sorry for the additional noise. Regards Heiko Am 19.12.2013 10:01, schrieb Eichner, Andreas - SID-NLKM: Narf. Send before attaching the images. So here it goes again, sorry.

Oh Andreas, blind me. Copied it into the POSTGIS layer but not the LINE Layer. Sorry for that. It works now as described, panning and zooming is ok. Btw, where to send the bugreport ? No problem. I just found https://github.com/mapserver/mapserver/issues/4483 which is tagged with MapScript. But reading through the bug description it sound like it is strongly related to your case. Since your problem seems to start in msDrawVectorLayer() this turns into a more general problem. I'm currently wondering why msProjectRect() transforms your request BBOX (-650,-650,250,250) into (-179.464412, 0.002066, 178.470560, 66.995391) and returns MS_SUCCESS. It seems to be a good idea to create a new issue at https://github.com/mapserver/mapserver/issues, tag it with Bug, Proj Support and MapServer C Library, reference the issue mentioned above and attach the map file, proj string and request that triggers the issue. You should also mention the found cause: msProjectRect() used by msDrawVectorLayer() doesn't create a proper query BBOX to fetch the features in such cases. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
