[Qgis-developer] python application
Hello, I'm trying to create a pygis-application with a code found in the quantum gis coding and application guide. I've programmed before but I'm new to python as such, so right now I'm basically just trying to break this down and understand how it works. To the issue: I'm using the code below but I get the invalid syntax error on the line of: self.connect(self.actionAddLayer, SIGNAL(activated()), self.addLayer) where ..actionAddLayer is marked.

[Qgis-developer] Bug working with size in data-defined properties?
Hi, I'm getting not expected results when working with data-defined size on symbols. I'm wondering if I'm doing something wrong or maybe it's a bug. The test it's quite simple: 1. Create a point layer with a sizeT table . 2. Create a point and give sizeT=10 . 3 Go to symbol layer (simpleMarker) and set size = 10 and see the result 3. Now active size in data-defined properties and pick the column sizeT. The result is not the same (I was expecting that). Neither in milimeters/map units. I'm working against master, and other fields as rotation are running as expected. I have had a look to the bug tracker but I haven't seen this one reported. It seems a pretty obvious bug so I rather to ask first here, because maybe I'm doing something wrong or maybe I'm expecting something erroneous. Sorry for the inconvenience. Thanks. -- Jordi Torres ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Bug working with size in data-defined properties?
Hi,Confirmed for me. It looks like size is multiplid by a factor 0.2. 6 value in data defined looks like 1,2 on screen. 1 look like 0,2. BTW behaviour is not clear since old advanced properties (proportion / rotation) have not been removed AND have a different behaviour. They do not use actual value, but act as a modifier of symbol size. New behaviour is by far better! (still lacks options to use non linear fonctions.. but it still is very nice) Can anybody explains that newbehaviour and it interfers with data defined style?

Re: [Qgis-developer] manageR update for 2.0
Using R via Sextante is also a good alternative. Shapefiles and Rasters are exported into R and it's possible to apply all sorts of R tools to them. There are a few good examples already in the algorithms tree. On Fri, Jun 7, 2013 at 11:27 AM, Giovanni Manghi giovanni.man...@faunalia.pt wrote: I also miss it.

Same with Postgis, but with Postgis there is some good autodetection (depending on the QGIS version). QGIS needs a specific CRS (ie. SRID) and a defined geometry type (point, line, polygon) for each layer and offers what it finds in the database or requires to enter what is undefined. You can only select the lines that are fully defined. That's very similar in the PostGIS and Oracle dialogs. It's just that Oracle doesn't have standard constraints, that limit the usable geometry types and SRIDs in a column and therefore also doesn't have a metadata table that carries that information, while PostGIS tables are usually quite constrainted. So for Oracle everything except the geometry columns themselves need to be scanned, while for PostGIS that can be taken from the metadata table in the usual case with applied constraints. If you create geometry column in PostGIS 2 with SRID 0 (meaning any) and type GEOMETRY (any geometry type) the outcome might be quite similar and you get a couple of lines for that column, each with a different combination of available geometry type and SRID combinations in the table plus another line where you can enter geometry types and SRIDs that you don't already have.

Re: [Qgis-developer] Oracle provider tests
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Il 07/06/2013 16:39, Jürgen E. Fischer ha scritto: QGIS needs a specific CRS (ie. SRID) and a defined geometry type (point, line, polygon) for each layer and offers what it finds in the database or requires to enter what is undefined. You can only select the lines that are fully defined. That's very similar in the PostGIS and Oracle dialogs. It's just that Oracle doesn't have standard constraints, that limit the usable geometry types and SRIDs in a column and therefore also doesn't have a metadata table that carries that information, while PostGIS tables are usually quite constrainted. So for Oracle everything except the geometry columns themselves need to be scanned, while for PostGIS that can be taken from the metadata table in the usual case with applied constraints. If you create geometry column in PostGIS 2 with SRID 0 (meaning any) and type GEOMETRY (any geometry type) the outcome might be quite similar and you get a couple of lines for that column, each with a different combination of available geometry type and SRID combinations in the table plus another line where you can enter geometry types and SRIDs that you don't already have.

Re: [Qgis-developer] manageR update for 2.0
Hi Filipe, On Jun 7, 2013, at 3:37 AM, Filipe Dias filipesd...@gmail.com wrote: Using R via Sextante is also a good alternative. Shapefiles and Rasters are exported into R and it's possible to apply all sorts of R tools to them. There are a few good examples already in the algorithms tree. I will have to test this. The value of manageR is the familiar R console and the simple import/export of raster and vector layers into the workspace. Although manageR is marked as incompatible with 2.0, I have gotten it to run after a fresh installation in QGIS, but the import function is broken, so it is of little use. I'll look into the example R scripts and see how that works out. Cheers, John ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [Qgis-developer] many SVG symbols disappeared
Hi ! So I've been working a little bit about that deprecated folder idea. It's not ready yet, but I have some questions since I'm not familiar at all with QgsProjectFileTransform nor with how SVG search paths work. https://github.com/olivierdalang/Quantum-GIS/tree/SvgLibraryRetroCompatibility *Here's what it does :* 1. Installation It creates a new svg_deprecated folder containing all original 1.8's symbols (alongside the normal svg folder, right in the installation root) 2. Project file conversion In the QgsProjectFileTransform::transform1800to1900() method, it updates the svg paths. - if the path starts with a / (which seems to correspond to the svg folder path), it prepends QGIS_PREFIX_PATH/svg_deprecated - if not, it does nothing (since it's an absolute path) *Questions :* A. Is it always right that a path starting with a / is a file inside the QGIS's svg folder ? (I never used SVGs search paths, if such a thing exists in 1.8) B. Is it okay to refer to the deprecated folder using an absolute path ( starting with QGIS_PREFIX_PATH ) ? I tried to prepend /../svg_deprecated instead, but with no success... (using absolute path has the major disadvantage of making the project file unportable). Any idea ? C. The file paths for SVGs in the print composer are absolute... So they still link to the 1.8 installation's svg folder. This works, but only until the user uninstalls 1.8... Is that OK ? D. Are there other places where SVGs from the library can appear in QGIS 1.8's projects ? (I've thought of SvgMarker, SVGFill and as images in the print composer) (E: is it better to already open a pull request for this kind of questions, even if the branch is not ready to merge ?)

But please don't make us and others rebuild their entire organization's cartography just because you don't like the symbols. Thanks, Duarte An option to get the old symbols should suffice, right? Instructions on what needs to be done with these symbols for each platform might also be helpful. Well, even though I agree with the new changes, it will be a harsh situation for those who have used the deprecated ones in their projects. And, kind of rude (from the users standpoint) to force the change and require a manual rebuild of existing projects. There are still some issues regarding the new symbol setup: 1) IMO, the deprecation of many symbols is fine, if they are moved to a 'deprecated' folder. Such a folder may or may not be part of the SVG search paths, but still in source and installed. Then, just like when you move or restructure a web site, create some path rewrite rules that will auto-update a 2.0 project and rewrite the deprecated SVG paths to the deprecated SVGs folder. This could remove the deprecated SVGs from the selector interface, but not break existing projects. When user goes to work with the symbol, the correct path is visible, but they can only select new-style SVGs for which to update the symbol, unless they specifically browse to the deprecated folder and link to a deprecated one again. I think such an approach will keep good karma with the user community. 2) Many of the new symbols are white as default. This is probably so they work well on top of a colored background when layered. However, this makes them very difficult to preview (especially on Mac). Either the widget view needs to have a medium gray background, or the default color for those SVGs should be gray (or maybe black, but gray would work better). This assumes that all those SVGs have color parameters that can just be changed later. 3) The new SVG backgrounds for labels do not yet support such 'layered' symbols. Currently only a single SVG can be used. There needs to be a decent selection of background SVGs for labels (e.g. road shields) that do not require layering. Layering backgrounds may not be a good fit for labeling in the future either, since single SVGs with drop shadows already slow labeling down.

[Qgis-developer] QGIS defaulting to no ellipsoid - Bug #7441, opinions needed
I'm posting this comment to the list to hopefully get some more opinions about bug 7741 - Measurements in degrees even when meters are chosen as map units I think this bug is caused by QGIS defaulting to None / planimetric for the ellipsoid for new projects. In 1.8 QGIS defaulted to WGS84. IMO The correct behaviour should be to restore this as the default setting. However -- I'm having lots of trouble understanding how this is supposed to work. The option to choose a canvas unit for a project is under the Canvas units (CRS transformation: OFF) group in the project properties dialog. If you hover over an option the tooltip states Used when CRS transformation is turned off. I'm pretty sure this tooltip is wrong -- since the choice DOES apply even if CRS transformation is turned on. HOWEVER, the choice is reset when the project properties window is opened UNLESS CRS transformation is off very confusing!! To add to the confusion there's 2 WGS84 ellipsoids listed - one is WGS84 and one is WGS 84. Choosing WGS84 actually results in Clarke 1986 being saved for the project! My gut feeling is that: - Ellipsoid should default to WGS 84 - The duplicate/bad WGS84 ellipsiod needs to be removed - The tooltip for canvas units needs to be fixed/reworded - The choice of canvas unit should save even if CRS transformation is enabled I'd like a second opinion on this though, since there may have been discussion around this behaviour which I'm not aware of.
