Re: [Qgis-developer] user-defined symbology defaults + project templates
I've pushed to a slightly modified version of both features. 1) Added default vector transparency for projects ; ui tweaks Would there be any thing else to add to vector defaults? Also, how about raster defaults? Perhaps the entire Rasters section from the main options dialog? 2) Save the default template to $HOME/.qgis/default.qgs (see UI in Options-General-Project Files) Next would be to implement a template folder (both saving and loading) and UI for custom template folder(s) - perhaps a single folder is good enough to make it simple? cheers, Etienne On Tue, Jul 17, 2012 at 8:44 AM, Etienne Tourigny etourigny@gmail.com wrote: On Mon, Jul 16, 2012 at 11:49 PM, Nathan Woodrow madman...@gmail.com wrote: On Tue, Jul 17, 2012 at 1:19 AM, Etienne Tourigny etourigny@gmail.com wrote: I'm glad others see this as useful!

Re: [Qgis-developer] New adv labeling freeze-thaw tools
I've updated and extensively tested this new tool (not all platforms) and it works very well. I have sent in a pull request: https://github.com/qgis/Quantum-GIS/pull/193 Again, here's the intro video: http://vimeo.com/dakotacarto/freezethawlabels (Note: I haven't had much sleep, so the video is a bit rough.) As an unexpected added bonus (well, unexpected to me), the tool helps greatly with slow label rendering options, like a polygon layer's 'free' and 'horizontal' modes. After the PAL labeling engine finishes with those modes during a canvas refresh (sometimes taking several minutes), just use the freeze label tool on the result. The subsequent canvas refreshes are magnitudes faster.

Re: [Qgis-developer] shapefile editing memory issue
Thanks for the quick response. Since my previous post, I have modified the code to eliminate all the calls to startEditing() and commitChanges(). I thought the memory problems might have been related to memory leaks in those functions. Now, I'm implementing changeAttributeValues() through the vector data provider to modify the attribute table directly without messing with the layer editing buffer, as recommended here: http://lists.osgeo.org/pipermail/qgis-developer/2011-July/015385.html However, some major memory leaks remain. As recommended in the previous post, I implemented my plug-in under valgrind on a Linux machine. Some output below highlights the changeAttributeValues() function as a possible culprit: 500,000 bytes 'definitely' lost with only a couple iterations of my algorithm. It's easy to see how gobs of memory can be lost after many thousand iterations. Any suggestions for a better way to update an attribute table repeatedly without losing so much memory?

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? You would probably need to run your plugin under a memory profiler like valgrind to see where the leaks are occurring. My apologies if that is too low level an answer.

[Qgis-developer] Tests for sextante qgis providers.
Hello all, I have had some difficulty with implementing the tests for Sextante, in particular, using QgsProviderRegistry. cf: http://code.google.com/p/sextante/source/browse/trunk/soft/bindings/qgis-plugin/src/sextante/tests/qgis_interface.py The providers seem not to load. Note that the qgis interface stub is initialized after a call to QgsApplication.initQgis(). If you have any pointers on what I could be doing wrong, it would be very much appreciated. Thank you regards, Camilo ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
