Regards Tim so I have created the project with qgis gui and saved it as a qgis project, now what I want is to send qgis a gpx file for using it's gps addon and take the snapshot of the project as a png file with --snapshot parameter however I couldnt find any way to give gpx file name as a project parameter does anyone know how can i do that ? My second question is when I called qgis with --snapshot parameter a gui of qgis appears for an instance is there a way to stop this?

Re: [Qgis-user] python plugin action vs mode tool
gLine = QgsGeometry.fromPolyline( [ QgsPoint(1,1), QgsPoint(2,2) ] ) # buffer with distance 0.5, use 5 segments to approximate curves gBuffer = gLine.buffer(0.5, 5) print gBuffer.asPolygon() The buffer() method is a great starting point to create a geoprocessing plugin. At the moment we want to implement a geoprocessing plugin with functions like buffer, union, difference etc. At the moment we realised it with Shapely. But this approach with third party libs is not nice and would be obsolete when QGIS offers the mentioned methods. QGIS native methods() based on GEOS would be the much better approach! What are your plans? Do you plan to implement union(), difference(), intersect() and relate() as QgsGeometry methods? A second question. I want to create a dissolved buffer polygon. To achieve this it is neccessary to combine all single objects p.e. LineStrings to one MultiLineString before buffer(). How do I concatenate single Linstrings into one Multilinestring?

But mine is suppossed to be a tool like the zoom tool, or the select tool: you click on the tool/plugin-button, the button gets activated/surpressed/darker, and keeps in that state until you select one of the other (zoom, select or info) tools. Current plugin-buttons do not get 'activated', when you click the plugin button it doesn't stay visually(!)'active', it's a clickclack button. To get the behaviour the only thing you have to do is to call map tool's setAction() or setButton() method. That will cause that when the tool is activated/deactivated, the associated action or button will get selected/delected. (This behaviour is implemented in QgsMapTool::activate() and QgsMapTool::deactivate() so that's why it's good to call them also if you reimplement these methods.) But still some details were not clear for me: for example it's not clear for me if you must make a new 'tool' when you want to make a plugin which does something with a click in the mapcanvas. No, you can use ready-made QgsMapToolEmitPoint tool and just connect to its gotPoint signal. Another question is the one about keeping a button 'activated'. I hope that one got answered above. My idea is to make some 'plugin-stubs' for different kind of simple plugins: eg starting with a very simple plugin which does not have an interaction with the map, to a tool like the xy-info tool which must handle a mouse click, and finally your copyright-plugin which was really helpful for me. But maybe a plugin stubb is not what I'm looking for: it's either to complicated because you want to make it technically useful, or it's to simple to be functionally useful. The idea was to hand beginners the first steps to to a really easy plugin. Probably the best way would be to create the same starting plugin as the template plugin written in c++. For the rest I think it's better to use code snippets... But maybe we need a code-snippets wiki page with questions like: - I want to keep de plugin button activated - I want to get hold of the active geometries of the active layer - I want to loop through all geometries of this layer - How do I test the type of a geometry - How do I make pixel coordinates from world coordinates and vice versa - How can I add a label to a (new) layer - How can I add a new geometry to a layer - How can I keep some project info by writing it to a project file etc etc. ... I should start this page myself maybe ... Well, some of those are already on PythonBindings wiki page, however some are probably missing :) I'll see what more could I add. For sure you can start a list of such simple tasks, we could address them with the code snippets. ps (referring to my buffer questions a while a go) if you point me to some 'easy' buffer algorithms, I'm ready to give C++ a try :-) ) Uhm, starting from r7986 you can use QgsGeometry::buffer() function that does exactly what you need :-) Obligatory snippet: gLine = QgsGeometry.fromPolyline( [ QgsPoint(1,1), QgsPoint(2,2) ] ) # buffer with distance 0.5, use 5 segments to approximate curves gBuffer = gLine.buffer(0.5, 5) print gBuffer.asPolygon() Enjoy!

Re: [Qgis-user] bug : ECW raster not display correctly
Considering most of the raster features have been merged for 0.9.2, perhaps the best is filing bug reports using a beta release of 0.9.2 (once it is released, I understand developers are very busy) Most users (the ones able to test and file bug reports) don't even know what replicate against svn trunk is.
