Zoom to a scale related to the layer bbox sounds much better than zooming in a fixed factor.

[Qgis-developer] Legend for proportionnal symbols and expression based symbols
Hi All, we have a long lasting problem with proportionnal legends in QGIS. It gets more problematic with V2, as those maps are so beautiful and popular. I'm starting some brainstorming to clarify fonctionnal specifications what we actually want to have legends in layers registry and composer working. Here are some exemples of what I would love to see in legends: - [0] proportionnal circles or square with 1 to 5 classes - [1] proportionnal symbols AND colors Now that we have expressions everywhere, we probably will have to handle legends differently than in other GIS, where legend is generated once, when user tune symbology. Let me explain: - user can now define expressions for size, color, rotation, border width... for any sub-marker (1 to n) of a symbol. - Moreover, we can use conditionnal expressions, and scale dependent conditions ($scale variable). - QGIS is also a server, we need to be able to generate legends working on really displayed datas. Conclusion, It now is impossible to correctly pre-generate the legend by analysing symbology properties. Does this sound possible to developpers to explore some other way? We could read real dataset to collect informations to build a legend, and eventually do some statistical classification to get discrete classes from continuous data? We could do that on live or on-demand update maybe. My idea was to collect rendered object in current canvas and current scale. BUT.. we can face discrete data - some kind of SELECT DISTINCT can do the trick - , OR continuous data - we need then to do some statistical classification to reduce the legend to 1 - 10 classes to get it readable. We also need some intelligence in those statistical classifications: - round values to keep it readable - display separate classes only if size or color distance is long enough so that human eye sees some difference on screen. ie: do not display for classes if symbol size varies from 0.5 to 0.7... - add some options in GUI to choose number of classes, type of legend rendering.. - keep the classification process fast (subset of data with random sampling?) - test all use cases, I'm mostly thinking of points symbols, but lines and polygons must not be forgotten. I'm sure plenty of scientists have already been theorizing all this. Any opinions? Could this be an idea for GSoC or other kind of training course? I'll be pleased to get feedback from the community.

Re: [Qgis-developer] Legend for proportionnal symbols and expression based symbols
I haven't had a chance to properly plan this out, but something which has been playing in the back of my mind is the idea of table legends. Take a look at the legend in this map: http://www.cartogrammar.com/images/vba/cervical_cancer.jpg I'm thinking the user could specify the variable which is changed along each axis, along with the min/max value for that axis and number of rows/columns for the table. Then the classes would be generated automatically (maybe equal ranges? equal count? user specified?) and the symbol automatically generated for each cell in the table. The size and spacing of each cell could be user controlled, so that this type of legend would also work for symbol layers. As I said, I haven't really sat down to work out exactly how this would work yet... it's just a rough idea which I've been toying with!

[Qgis-developer] 64 bit busted, install 32 bit instead?
From some posts I have read it looks like the both the 64 bit Windows standalone and Osgeo4W installers are busted and one should install the 32 bit version instead. Is this correct? I used the 64 bit standalone installer back in early October and am missing some GDAL libraries and certain GRASS tools do not work, giving me a GDAL library error. Have a look at the thread here: http://osgeo-org.1560.x6.nabble.com/QGIS-2-0-Win-standalone-busted-td507 8946.html. I have a similar situation. Has the 64 bit installer been fixed or should I install 32 bit version instead?

[Qgis-developer] qt/ui different dialogs/windows/docks etc
Hi Devs, currently we have all kind of different dialogs popping up, from plugins, processing, actions etc etc. some have a close button in bottom, some have little close icons in the titlebar, some have all on windows and none on linux etc. some are dockable, others are not. there are already some issues related to this: http://hub.qgis.org/issues/9126 http://hub.qgis.org/issues/9141 http://hub.qgis.org/issues/8699 Different but also in the better usability category: http://hub.qgis.org/issues/9083 maybe we should start some ui/usability-team, which creates tasks for this kind of problems, propose/finds solutions (he, qt is huge) and maybe also can create some guidelines about a good dialog/popup/plugin should look like? any volunteers? Or should we ask this on the userlist? Regards, Richard Duivenvoorde ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Owner of qgis-web-client repo?
Hi Andreas, Am Mittwoch, 4.

Maybe just added by someone else? Where can I see who is the owner of the repo? Is it Tim or Pirmin? Or someone else? All PSC members are in the owner group. Thank you for your help. I can commit stuff to this repo, but I can't change settings or add collaborators. You should now have admin permissions for the QGIS Web Client repo.
