I agree the old versions of symbology and labeling should be removed rather sooner than later. It would increase pressure on developers, financers and users to implement the really important bits that are missing. If we do this in the master version it won't hurt existing users.

Re: [Qgis-developer] What will be in QGIS 2.0
Dear All, I followed your discussion with interest and I have a feeling there are two aspects to be considered: One is the developer's perspective and one is the user's perspective. From a developer's perspective there is the api change, new raster architecture (and a lot more I cannot name, basically under the hood). From a user's perspective 2.0 should be clearly distinguishable from 1.* (icons, GUI) and things long introduced (new symbology, new labelling) should be standard and work reliably but without regression compared to the old methods. So the project should take its time to satisfy both perspectives. my two cents Bernhard __ Information from ESET Mail Security, version of virus signature database 7290 (20120711) __ The message was checked by ESET Mail Security. http://www.eset.com ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

I'm using the new label engine, and manually adjusting many of the labels for x/y and rotation. Labels are in map units, with parallel-to-line feature layout. Is there a means to have PAL layout the labels, then do something to freeze (write) *all* labels' x/y coords to the data source? I'm not aware of any straightforward solution. I have heard of some plans to provide PyQGIS wrappers for classes responsible for (PAL) labeling, so with your Python skills you could create a script/plugin that would take care of freezing labels - though the API would probably need some tweaks to allow not only draw the resulting labels, but also fetch the label positions. Freezing the labeling and editing of label placement were things I wanted to do from the early times when playing with PAL, but never got to it close enough :-) Thanks for taking the time to address my question. I've actually coded this in C++ and it works pretty well, as a rough proof-of-concept [0]. I'd appreciate it if you checked it out, if you have the time. It's my first attempt at an actual C++ feature. There's no GUI, but it can be bluntly toggled for testing like this: * Load a line vector layer with x, y, and rotation fields in its attribute table * Configure label engine settings (I only tested with parallel-to-line settings noted above) * Enable editing for layer and the labels of its features within the map canvas extent have their coords and rotation written to the attribute table * Try move, rotate, and change label tools to test (all work well for me, and no longer 'reset' the label on first edit) The caveat here is that, on every canvas update while the layer is still editable, labels are always written to the table, even if they have already been and are identical. This causes a lot of writes that can take time to undo if layer editing is cancelled. This can be fixed. It only writes what's visible in the extent (actually a good feature), but panning around at different zoom levels, or just zooming out to layer extent if using map units and showing all labels, eventually writes most or all labels to the table. I'm thinking of wiring it to a toggle-able button in the adv. labeling toolbar. Then a user can leave it on or off while they pan. A user can then zoom in on a troublesome area, freeze the labels there, toggle freezing off, then adjust the frozen labels, while leaving the rest dynamic. There can be other settings, like only freezing selected feature's labels.

In this case it was an easy sell since we are using the work in the project to build software that 'must just work' and having tests will be critical in providing that assurance. That said I think in all cases, if a client has paid for something the will want to know that it 'just works and keeps working down the line' too.

Re: [Qgis-developer] WCS and Raster improvements for QGIS
Hi In my opinion, it is better to use the Qt classes for the network requests than curl. In QGIS, we have QgsNetworkAccessManager, which picks up automatically the network settings from the options tab (proxy settings, exclusion list, password, disk cache). It has nice progress reporting by signal/slot, the possibility to interrupt the network request and a disk cache. And the possibility to provide custom implementations for all that if necessary. Like this, WFS, WPS, WMS providers, plugin installer and open layers plugin (and third party python plugins) have a unified method to do network requests. No need to use a different network library for each one (and the mapping is never 1:1, there is always loss). So while it might be quicker (in terms of development time) to use the GDAL provider, a standalone provider is always more native and flexible (that's also the reason there are QGIS vector providers for postgres, wfs, gpx, spatialite, grass while everything can be read with the OGR provider).

Re: [Qgis-developer] Freeze dynamic labels in advanced labeling

Hi, +1 for that functionnality. I wrote a plugin to duplicate a layer and add advanced labeling fields in order to quickly make a labeling ready layer. having XY prelocated thanks to PAL is big feature I miss. (I have some more things to fix before releasing it.. ) I have an immediate need on my current project for just such a plugin! Please contact me directly if you don't mind sharing it a bit before release. The logic in my patch to freeze dynamic labels comes just after the labels are drawn to the canvas using PAL. It currently can't write all layer labels to its source (or a duplicated layer) unless all the labels can be shown in the canvas when zooming to the layer's extent, which is possible in some labeling setups. In other words, with my approach, it requires some specific setup or interactivity from the user. The freeze labels tool I'm working towards (need it on my project with thousands of labels right now) is basically an interactive one, similar to the other labeling tools. It may be possible to mimic those actions in a plugin, to freeze all labels for a layer, but it won't be very elegant until the Python access is crafted, as mentioned by Martin (unless you are coding your plugin in C++, I guess).

[Qgis-developer] shapefile editing memory issue
Hello List: I am developing a QGIS plug-in for the purpose of running simulation models for unique land units, as represented by polygons in a polygon shapefile. Essentially, the plug-in uses spatial information in the polygon layer to write a simulation model input file. It then uses Python's 'subprocess' module to call the model executable and run the simulation. It then reads an output file generated by the model, sets the polygon shapefile to be editable, changes some attributes based on the model output, and then commits those changes. Then repeating this in a loop for each feature in the polygon shapefile. I've also included an optimization routine for the purpose of model calibration. This essentially means doing the above procedures repeatedly tens or hundreds of thousands of times. After each model simulation, the updated 'simulated' attribute values are compared with other attributes that contain 'observed' data. The optimization then repeatedly adjusts the model parameters until simulated and observed data are in best agreement. This process can take many hours or days, while I am repeatedly editing the shapefile and commiting the edits. However, I am not adding or removing any features or attributes. Problem is the memory slowly creeps up and if the optimization takes too long, I'll run out of memory and QGIS will crash. I notice that if my optimization routine does finish, I can completely shut down my plugin's dialog window, but the memory usage remains high. This makes me think the problem is not in my plug-in. Any ideas for me? Thanks, Kelly ~ Kelly Robert Thorp, Ph.D., P.E.

Re: [Qgis-developer] WCS and Raster improvements for QGIS
Given the planned work on the composer I wonder if you're considering to move the print code (e.g. [1]) outside of the GUI/app control, and make it available for the python API, maybe in a QgsComposerPrinter class.
