[Qgis-user] QGIS Master error Modeler Sextante GRASS GIS extent
Hi list, I get an error in the Sextante Modeler to use any GRASS GIS algorithm, since it requires you to enter the values of the extension, and the default setting does not work [Use min covering Extent]. How I can define the extent is calculated from the input layers?. My solution has been to enter the values 1,1,1,1 as extension. Thanks, Error: Ha ocurrido un error mientras se ejecutaba el código de Python: Traceback (most recent call last): File "/usr/share/qgis/python/plugins/sextante/modeler/ModelerParametersDialog.py", line 836, in okPressed if self.setParamValues(): File "/usr/share/qgis/python/plugins/sextante/modeler/ModelerParametersDialog.py", line 604, in setParamValues if not self.setParamValue(param, self.valueItems[param.name]): File "/usr/share/qgis/python/plugins/sextante/modeler/ModelerParametersDialog.py", line 773, in setParamValue return self.setParamExtentValue(param, widget) File "/usr/share/qgis/python/plugins/sextante/modeler/ModelerParametersDialog.py", line 759, in setParamExtentValue value = widget.itemData(widget.currentIndex()).toPyObject() AttributeError: 'NoneType' object has no attribute 'toPyObject' Versión de Python: 2.7.5 (default, May 12 2013, 12:00:47) [GCC 4.8.0 20130502 (prerelease)] Versión de QGIS: 1.9.0-Master Master, fb15725 -- --- .~. / v \ //\\ /( )\ ^`~'^ ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Qgis - automate operation
Hello Lucien, I believe the best place to start would be by checking PyQGIS cookbook: http://www.qgis.org/pyqgis-cookbook/intro.html If you wanna take a very basic crash "course" of Python to get some bearings, you can try codeacademy: http://www.codecademy.com/tracks/python. or http://www.learnpython.org/ Some more intense\serious approaches would be: http://learnpythonthehardway.org/book/ http://www.greenteapress.com/thinkpython/ Best regards, Alexandre Neto On Fri, Jun 14, 2013 at 12:09 PM, BLANDENIER Lucien < lucien.blanden...@unine.ch> wrote: > Dear all, > > I'm trying to automate some basic operation (import of raster, select > color palette, ...). > > I assume it is possible to do it with Python scripts but I don't know this > programming language...
