[Qgis-user] Problem loading plugin only on Qgis startup
Hi evrybody, I started to create plugin from plugin builder, it works fine when I enable it from Manage and install plugins when Qgis desktop is already open, but if I close Qgis with my plugin enabled, when it starts next time raisa an error at startup: error calling class_factory() method and ImportError: No module named resources_rc So I need to relaod it with plugin reloader, then it works fine Of course the file resources_rc.py exists and I compiled it with pyrcc4, the first line of my plugin file are: --- import sys # Import the PyQt and QGIS libraries from PyQt4.QtCore import QSettings, QTranslator, qVersion, QCoreApplication from PyQt4.QtGui import QAction, QIcon from PyQt4.Qt import QApplication from qgis.core import * # Initialize Qt resources from file resources.py import resources_rc # Import the code for the dialog from ctr_import_dialog import ImportCtrDialog import os.path --- Maybe I need some other modules or I'm not using the right order?

Hi Nathan, oh, good to know. I'll try the workaround for now. I thought the layer id would have a greater importance :-). Many thanks Burghardt *** mailto:burghardt.scho...@stadt.wolfsburg.de ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] QGIS/ArcGIS python interference
hi Torsten
I had a similar problem to run an external water model (of a client)
requiring a different set of python libs and linked libraries... I use
python subprocess command, that is more or less the same mechanism
applied by Processing Toolbox to run some external command providers.
In this way you can communicate with your application using stdin,
stdout and stderr... and receive exit codes.
More complex interprocess communication can be obtained parsing
stdout, or piping on common files... or a lot of other mechanism.
a good support by qgis can be obtained creating a Processing script
that execute subprocess command of your application. This script can
manage processing progressbar basing on result read from stdout.
I hope this can help you
regards, Luigi Pirelli

Re: [Qgis-user] qgis-server vs layer id

[Qgis-user] Grid extent resctriction on some SAGA algorithms too extrict
Hi there, i was trying to conduct some hydrological analysis using SAGA through the Processing Toolbox and as always when i try to run the 'Channel Network' algorithm i get the warning input layers do not have the same grid extent. Even when the layers have roughly (roughly in this case means up to the ninth decimal place) the same extent. I've tried to clip the rasters to exactly the same extent without any success so i assume there are only a few solutions left which aren't easy or practical. Then i found the script, /SagaAlgorithm212.py/, and the function responsible for this check /checkParameterValuesBeforeExecuting/. IMO the grid extent should be checked up to the 7 or 8 decimal places not the full mantissa (16 decimal places in my case, for and EPSG:4326 raster layer). -100.00013869,17.99986095 : -98.999861031065,19.000138968900 -100.00013840,17.99986089 : -98.99986018,19.00013876 Is there any reason behind this behavior? Could the extent check be less strict?

Re: [Qgis-user] QGIS/ArcGIS python interference
Hi Luigi,
I think I got the idea of what you meant. Actually, in the very beginning befor
using the QGIS plugin functionality I wrote a pure PyQT-Dialog which I called
using the QGIS processing script connector. With the inputs I fed a simple
python script, which however didn't applied any ArcGis-Python module. Ok, it
might be worth, to go that step back to this more simple approach.
Thanks much for your thoughts!

Windows7/64bit rules the hardware in the department.
At one time I agreed to program a workflow that does all the necessary
preprocessing and final gridding depending on quite a number of input
parameters. Of course, I had no plan to cut me off as a (quite happy) QGIS
user who by using QGIS in fact did an altruistic favour to the colleagues
but esp. to the IT dep. ;)
So, I wrote a general python script using arcpy/spatial analyst... that
accepts the input parameters as dictionary provided on command line or
using a seperate python script defining a class holding the input
parameter. I created a QGIS dialog plugin that collects all those
parameters in an appropriate manner in the form of:
start /i cmd /c python myWorkflow.py -d configDict = {'inputIsoLineFile':
rU:\... etc etc}
I also learned I had to copy the xxx64bit.pth-File (don't remember the
correct name right now) from the ArcGIS-Python directory to the QGIS python
site-packages directory.
Now, beside some error messages (some gdal dll in QGISetc are not real
32bit or so), which seem to have no real impact on the run itself, I
got my first grids, which I sent to a post processing befor leaving the
desktop.
This to getting work cost me a lot of extra time. I mean, I did this en
passent while fullfilling my main work. So I'm really interested in what
would be your approach to that! In fact to me it seems much more easy if I
could start a cmd session that has no inherits from what so ever and comes
with the environment as if I would start it from the Windows menu.
Sorry for the long description, appreciating some thoughts of you!

[Qgis-user] website template for local QGIS user groups
Dear local QGIS communities, the QGIS Project now provides a clone of the QGIS U.S. User Group site [1] at https://github.com/qgis/qgis-template.github.io. The aim is to provide a generalized template, that local user groups can use for their website. The british [2] and italian [3] QGIS user group already started their site based on the template. You are welcome to join but of course you don't have to. [1] http://qgis.us/ [2] http://qgis.uk/ [3] http://qgis.it/ If you have questions or need help, subscribe and send an email to the Qgis-community-team list. Kind Regards, Otto ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] making mistakes with raster calculator
Vou can do it with: (( 3_NDFI@1 = 0 ) * 0) + ((3_NDFI@1 0)*5) Claas Am 09.04.2015 um 00:09 schrieb Giacomo Fontanelli: Dear forum I use QGIS 2.8.1. I have a raster map, Float32, pixel values range from -0.7 to 1. I Would like to make a map with pixel having only two values: pixels with values = 0 should be 0 pixels with values 0 should be 5. the sintax ( 3_NDFI@1 = 0 ) =0 AND ( 3_NDFI@1 0 ) =5 doesn't work because it produces a map with only 0 values. In order to reach my goal I must do ( 3_NDFI@1 = 0 ) =0 AND ( 3_NDFI@1 0 ) =1 then multiply result by 5. What's the problem? Is it possible to fulfil the purpose with only one raster operation?

[Qgis-user] Georeferencer does not start
The Georeferencer plugin does not start in QGIS 2.8.1 nor latest dev version. The plugin is - installed by default - activation is checked in plugin manager and - appear in C:/OSGeo4W64/apps/qgis/plugins/ dated to 26-02-2015 - appear as a button and menu item But unlike some weeks ago, the georeferencer dialog does not appear when pressing the button. I have deleted the .dll and done an OSGEO4W reinstall of both 2.8.1. and dev without luck. Is this a bug, or could it be something on my Windows 7 or Symantec Endpoint protection anti virus applications stopping the dialog box? Although a check didn't reveal any logged problems there. I have no problems with any other QGIS dialog boxes. Karl -- Karl Brix Zinglersen ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
