[Qgis-developer] Fwd: #8884 Symbol too small in legend when map units are used
Forwarding to qgis-developer mailing list (he wrote to me :-) ) -- Forwarded message -- From: Andreas Neumann a.neum...@carto.net Date: Tue, Apr 15, 2014 at 3:14 PM Subject: Re: [Qgis-developer] #8884 Symbol too small in legend when map units are used To: Luca Manganelli luc...@gmail.com Hi, Confirmed. We would need a way to override the symbol map unit size with a size mm - solely for the display of the legend.

Simple test case: pick a vectorial point layer with the default style, see the TOC legend; open the style properties, go to Style and switch the units to Map units. As you can see, the symbol is very small. The situation is worse if you use a SVG symbol, it's impossible to distinguish which is on the map and which is on the legend. https://hub.qgis.org/issues/8884 [1] Links: -- [1] https://hub.qgis.org/issues/8884 ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer -- It means your future hasn't been written yet.

Another point : apart from performance issue, I cannot see any reason why *not* to enable symbol levels. Are there situations were users do want different symbol layers to overlap ? I think there are such situations, from the top of my head: - with symbol levels you cannot see the rendering progress (everything is rendered at the end) - this makes quite a difference with big layers - you don't always want the symbol layers to be blended (different appearance) - not all renderers need to support symbol levels I don't think we should go with symbol levels always on.

[Qgis-developer] New plugin RasMover
Hello All, I created a new plugin that move all active raster, using a new temporary raster. http://plugins.qgis.org/plugins/rasmover/ This plugin is very useful to fine collimate Raster with vector layers. Please, test it and approvate it if you like. Thank you Roberto ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] different projects, same layers IDs
Hi all, sometimes it is necessary to create and publish with qgis server multiple projects, that are made from the same template containing a bunch of layers that are the same in all projects. IDs for this layers are the same, then on qgis server issues happens http://hub.qgis.org/issues/7956 http://hub.qgis.org/issues/10068 as suggested here http://hub.qgis.org/issues/7956#note-5 it seems that adding the project name to the actual layers id seems a good and easy solution. I was remembering that there was a patch/pull request about it, but can't find it. cheers! -- Giovanni Manghi Faunalia.pt Sistemas de Informação Geográfica Open Source Portugal Web: http://www.faunalia.pt Email Jabber: giovanni.man...@faunalia.pt PGP Key available Tel. + 351 96 7058216 -- ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Ok, so ... why the UI asks the user for integers ? And what is the meaning of two layers with the same number ? Integers are there for convenience... with more complex scenarios (e.g. roads with highway crossings) it may be handy to have numbers instead of just a pure list, and to possibly have holes between the levels. What about a UI with the list of symbol layers and some up/down buttons ? That would be possible, but maybe harder to use. In the table view, you can see symbols and their levels at once. In a simple list with up/down buttons you need to split the symbols into symbol layers and it is more difficult to identify what are the levels for one symbol (IMHO). Another point : apart from performance issue, I cannot see any reason why *not* to enable symbol levels. Are there situations were users do want different symbol layers to overlap ? I think there are such situations, from the top of my head: - with symbol levels you cannot see the rendering progress (everything is rendered at the end) - this makes quite a difference with big layers If I am correct, you can still see the progress. You will see the first symbol layer, then the second one, etc. Yes, but only once all features have been fetched from the provider - and that interval usually dominates the rendering time. So, with a layer that takes 5 seconds to render, there will be maybe 4 seconds when you see nothing from the layer.
