Re: [Qgis-user] [QGIS-Developer] Dropping the extra label placement algorithms?

Label placement took a lot of time and efforts in the past and this is the outcome. It's true, there is no real need for it while on screen, but it could be very useful in Layout. The problem is similar to generalisation, you need proper data to support label placement. Losing the relationship

Specialists may suggest a more focused approach, but you can use several tools and approaches. You can start with the PDAL library (pdal.io), use the tools in GDAL (grid tools) or prepare a workflow using GRASS algorithms in Processing. c Il ven 20 apr 2018 17:42 C Hamilton

Re: [Qgis-user] [QGIS-Developer] QGIS 3 Print Composer - Page Properties

I suggest to provide the same interface as version 2 calling this "default page size" and explaining that every page could get a different size, right-clicking on the page. Most users make one-page maps and they would never need this otherwise vital feature. c On Mon, Apr 2, 2018 at 10:01 PM,

Re: [Qgis-user] Editing a Postgis view

Ciao Andrea, by default Postgresql views are read only. Even the simplest view made in Postgresql needs a rule to be updated. After writing a statement for a view, just take the habit of writing the rules for insert, update, delete. Please read the chapter on the Rule System in the Postgresql

Re: [Qgis-user] QGIS 2.16 DB Manager and spatialite view

Hello Enrico, QGIS implements an older arrangement from the first version of Spatialite. The views share metadata with tables in geometry_columns. I think that QGIS should use the proper metadata table as well. It's time to do it as Spatialite is at version 4 and the views_geometry_columns comes

Ciao Luca, if you mean cutting the stream and manually assigning a width to every arc, well, it's not the right procedure anyway, but if you deal with a network as a network you should allow waterflow grow for other reasons besides going downhill. Every node brings affluents so more water becomes

The correspondence is not always true, several not-free formats are writable by OGR, but, as a precaution, they are not editable in QGIS. This is the case for files that are able to style features: MapInfo, Intergraph DGNs, etc. could be writable asking the user losing stylesif he would be

Hello Priscilla, there is a plugin that will enable you to open MapInfo .wor files in QGIS. MapInfo styles are a double faced beast, features could be styled inside the .tab file, but themes are added in the wor(kspace). Both are well documented, OGR (a part of GDAL -- www.gdal.org -- which is the
