[Qgis-developer] Virtual column joins
Greetings, Earlier this week, I ran into the need to do a temporary join between two datasets that would have relied on a virtual column. It however seems that QGIS is unable to do so as the virtual colum did not appear in the list of available columns to use to establish a join. Is that a known limitation or an implementation issue?

[Qgis-developer] Virtual geom column
Hi, Now that we have virtual columns in QGIS, I wonder if we could improve this towards virtual geom columns. Often, there is point (x/y, lat/lon) data in some non-GIS database and you only have read-only access. Rather than copying this data to some other database/format it would be nice being able to visualize the data on-the-fly. How complicated would it be to introduce such a virtual geom column in a future QGIS version? Thanks, Andreas ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [Qgis-developer] Export to web: OpenLayers, Leaflet, Threejs
Hi all, +1000 for this merge René-Luc and I have also created a very simple (unpublished) plugin as a proof of concept to export pseudo mercator tiles from the project layers, very similar to QTiles plugin, but with a simple but usefull addition : Tiles are first saved in a mbtiles database, then exported to a simple architecture similar to TMS but with no duplicates in tiles. For example, a completely blue tile from the ocean will be stored only once. A JSON file stores the correspondance between zoom / x and y and each png. We have a simple but usefull leaflet tilelayer definition which can use this particular format, thanks to the plugin Functionnal tilelayer ( https://github.com/ismyrnow/Leaflet.functionaltilelayer ) So no revolution here, no real new concept, but a very simple way to export QGIS rendering to a format which can be used offline with any HTML browser, which means it is usable with Iphone, android, etc. I think we could add this kind of tiles export feature to the merged plugin.

[Qgis-developer] Export to web: OpenLayers, Leaflet, Threejs
Hi all. I'm doing a course, and we found several potential issues, some of them related: * openlayers export: if a layer has a transparency in QGIS, the exported page has black polygons instead of transparent ones * the opacity control of qgis2leaf does not seem to work. More generally, the three plugins do a very similar job, but have different interfaces, and different behaviour, e.g. one shows a preview, two open an external browser directly, others not, two allow to save the result to a specified layer, etc. It would be very good if the interfaces and the behaviour would be unified, for maximum ease of users. I do not mean to change much in the plugin itself, just cosmetic stuff. Perhaps even better if the three could be unified (and possibly brought to core), but that requires obviously much more effort. I'm available for help if useful.

Re: [Qgis-developer] Data-defined buttons for en masse size and rotation
Hi Regis, Here is a PR for one element of this feature https://github.com/qgis/QGIS/pull/1853 It's only the ground work, so you have no GUI to help you setup the expression for the size rotation, but you can use scale_exp and scale_linear to define your value range and the corresponding symbol size range. It works for line width too. The legend's symbol does dissapear though, but I believe it's due to the data defined size. I'll work on the legend to have something meaningful when using size expressions. If you can recompile the branch and give feedback, it will be welcome. Thanks, V.

Re: [Qgis-developer] Export to web: OpenLayers, Leaflet, Threejs
definitely a great addition. I think that any plugin or script that exports a qgis project to another format (so it uses QGIS as a front end for easily setting up layers, symbology, etc), can fit in here. We can create a small framework and then plug converters into it, so they use a similar interface (with basic common parameters such as the list of layers to include) and some custom inputs for each converter.

We have a simple but usefull leaflet tilelayer definition which can use this particular format, thanks to the plugin Functionnal tilelayer ( https://github.com/ismyrnow/Leaflet.functionaltilelayer ) So no revolution here, no real new concept, but a very simple way to export QGIS rendering to a format which can be used offline with any HTML browser, which means it is usable with Iphone, android, etc. I think we could add this kind of tiles export feature to the merged plugin. Anyway, let's gather people around to contribute ! 2015-01-22 16:56 GMT+01:00 Victor Olaya vola...@gmail.com: yes, when i said our plugins i meant his one (qgis2leaflet) and myone (qgis2OL3) :-) 2015-01-22 16:52 GMT+01:00 Thomas Gratier osgeo.mailingl...@gmail.com: Hi, I maybe misunderstandood but I think Victor was already speaking about ol3 e.g https://github.com/volaya/qgis-ol3 Thomas 2015-01-22 16:39 GMT+01:00 Luca Delucchi lucadel...@gmail.com: On 22 January 2015 at 16:36, Victor Olaya vola...@gmail.com wrote: I am discussing with the author of the qgis2leaflet plugin about the possibility of merging our plugins into a single one.

Re: [Qgis-developer] Processing disappeared from QGIS master?
Hi Alexander, which version of SAGA do you have? Processing provider was updated recently and some old SAGA versions are not supported yet. It should work with SAGA 2.1.2 and 2.1.3 I think that may arise a problem here, because ubuntugis-unstable [0] just have SAGA 2.1.1 for ubuntu versions 14.XX, and most users of ubuntu-like-systems use ubuntugis-unstable to install these packages and dependencies. How can we get around this issue?
