Re: [Qgis-user] Double Labels on a SVG Marker
Hi Dave, Can you be more specific? I tried to reproduce your case but didn't succeed. What kind of data are you using? Points or Lines (with arrow heads)? What version of qgis? What platform. Maybe you can even provide some data and the qml (style)? Kind regards, Raymond On 28-12-2019 21:31, Dave Gardiner wrote: I have a svg marker (an arrow symbol) which when a single label is assigned to display an attribute, the attribute is displayed twice (i.e. displayed at either end).

[Qgis-user] Double Labels on a SVG Marker
I have a svg marker (an arrow symbol) which when a single label is assigned to display an attribute, the attribute is displayed twice (i.e. displayed at either end).

Re: [Qgis-user] filled polygon error
Hi, Just speculating as I do not know how simplification works but I imagine that only more complex shapes are being simplified. I also imagine that this simplification depends on the zoom level and depends on the total number of vertices in a shape therefore some island would not be filled in. I would expect multipolygons to exhibit this simplification faster than the polygon equivalents because they are more complex. Depending on how files are being exported, some may be exported as polygons or multipolygons depending on file formats. This may be what is happening with the FIX Geometries. I imagine multiSurface may be treated as a mesh by QGIS??? Meshes have been introduced later in QGIS and I suspect it may not use the simplification. This is pure speculation on my part. Bug reporting is done here. https://www.qgis.org/en/site/getinvolved/development/bugreporting.html Nicolas > Le 27 déc. 2019 à 14:43, malcolm a écrit : > > > Maybe a bug report, if so please advise where to submit. > > With simplification turned on, some complex polygons with holes inside get > filled when zoomed out.

Re: [QGIS-it-user] importare file .h5
Giacomo Fontanelli-2 wrote > sapete come farer per importare file .h5 in qgis 3.10? Ciao Giacomo, con quale versione di QGIS (e GDAL) esattamente hai problemi e su quale sistema operativo? Comunque sono stati riscontrati problemi su Windows: vedi http://osgeo-org.1560.x6.nabble.com/QGIS-Developer-Problems-loading-and-using-GDALinfo-on-hdf5-files-only-on-Windows-td5421777.html e https://github.com/OSGeo/gdal/issues/1428 Si tratta dello stesso problema? A presto.
