Re: [Qgis-user] problems to split images
Jan,
Have you tried the Image Cutter plugin at:
http://www.mappinggeek.ca/QGISPythonPlugins/image_cutter/indexInternet.html
You can install it from the repository at:
http://www.mappinggeek.ca/QGISPythonPlugins/
We used it to tile images for maps.
It will work as long as you don't have any spaces in your path or file names.

Subject: [Qgis-user] problems to split images
hi !
i try to split a image into 4 new tiles by gdal_translate - the problem
is, that there was a border between the image in right-axis.
i create a little script for the work:

Re: [Qgis-user] Lost Map Navigation Panel
Lene Fischer from Denmark suggested this link: http://osdir.com/ml/qgis-user-gis/2011-07/msg00333.html which suggested: You can remove (or rename) HKEY_CURRENT_USER\Software\QuantumGIS\qgis\UI\state in regedit. Unfortunately that also resets all toolbars and docks. Unfortunately my user doesn't have the privilege of editing the registry so that solution is out. In the same thread, the message: http://osdir.com/ml/qgis-user-gis/2011-07/msg00334.html suggests: Ok, I wonder what's wrong with that toolbar. One could check if it's just offscreen with qgis.utils.iface.mapNavToolToolBar().geometry() and if it is, move it back with qgis.utils.iface.mapNavToolToolBar().move(0,0) this should work to fix the problem.

Re: [Qgis-user] Does QGIS Currently Support WCS? or WMTS?
Jürgen, When I try and add a URL to the WMS layer definition with a &SERVICE=WMTS parameter it is stripped out. Unfortunately that is the only part of my URL that is the difference with the WMS URL so without the WMTS service specified it defaults to the WMS service. So I haven't been able to get WMTS to work.

Nathan, Yes, I set up the proxy server properly. If I don't set it up then my connections to the plugin repositories and to WMS servers don't work and I've tested them and they work OK. Right now I'm focusing on trying to identify ports or protocols that this plugin might be using that my Windows firewall might be blocking but I'm not making much progress so far.

I tried using this plugin the other day and found that a lot of important DXF element attributes were missing. Is there currently a way to get things like the layer name and the textstring imported into the SHAPE files using this plugin? If there is not, are there any plans to extend this plugin to do this? If help is needed to work on improving this plugin, I would be interested in lending a hand since I am keen on seeing this functionality added. Bob ** Bob Bruce, FEC, P.Eng.

RE: [Qgis-user] Tema annotation
Orlando, do you save the text orientation as an attribute in the SHAPE file? I have cadastral data in SHAPE files that we create from our DXF files and save the orientation angle as an attribute TEXT_ANGLE. I then use this attribute in the "Data defined alignment" to individually orient each piece of text. In my case the text is actually line shapes but this will work just as well for text attributes contained in point shapes. Don't forget to turn off the drawing of the actual point in the symbology section of the layer properties (I set no pen for the fill and no line for the outline for this) Bob Bruce From: qgis-user-boun...@lists.osgeo.org [mailto:qgis-user-boun...@lists.osgeo.org] On Behalf Of legio nostra Sent: Monday, November 23, 2009 8:16 AM To: qgis-user@lists.osgeo.org Subject: [Qgis-user] Tema annotation Olá a todos.

[Qgis-user] GPS Plugin for Windows
(I'll try this again in plain text) I have published the GPS plugin to my plugin repository at: http://www.mappinggeek.ca/QGISPythonPlugins/Bobs-QGIS-plugins.xml. This was built using the QGisTrackGps plugin as a starting point. Anyways, this is available for use in QGIS on Windows now and I'd appreciate it if people would give it a try and provide me with feedback. If you are using the plugin with a standalone (non OSGEO4W) version of QGIS then you probably will have to download and install the Python for Windows extensions library from http://sourceforge.net/projects/pywin32/files/ .

RE: [Qgis-user] Congratulations to all :-)
I strongly agree as well. Three years ago I included QGIS in a presentation that I gave here in Winnipeg of FOSSG and users were lukewarm about it. This past Friday I made a presentation on QGIS and its Georeferencer plugin at the local GIS users group meeting, and although there was only one other QGIS user in the meeting of over 100 people, the users at the meeting were quite impressed with it. I expect that the user base will grow rapidly now that all the development has been done on it. My thanks to all of the developers who make and maintain this excellent software.

Only two remarks related to the zoom_to_point_BB metadata: 1. There is a wrong entry in the repository: zoom-to-point-bobb.zip This tag is optional, so if you have a static url to the file (as you do), you can safely remove it at all. But if it's present, it has higher priority than url in recent versions of the plugin installer and causes problems. 2. Version numbers in the __init__.py and repo xml don't match.

RE: [Qgis-user] QGIS Image Clipper Plugin Available
Thanks to everyone who has tested this. I made a problem report on Wed
2009-08-26 9:22 AM under the subject line:
"[Qgis-user] QGIS API QgsMapToolEmitPoint Is Not Working Now andQGIS
Crashes"
When the image clipper plugin stopped working for me. I tracked the
problem down to the point where it was going to grab the location of
mouse clicks on the canvas. Unfortunately I couldn't figure out why this
was happening because I believed that I was following the right
procedures according to the documentation. I never did get any response
to this query but I didn't worry about this then because all of my
existing installations were working OK. Now I just tried updating my
OSGEO4W installation with the latest version of QGIS and I am getting
this problem on this workstation. So it seems to be related to something
to the way that I am getting the mouse pointing. And it the problem only
appears after I upgrade the installations (or install a new download)
using OSGEO4W.
Hopefully someone who is smarter that I am about this stuff can spot
what is causing the trouble.
Incidentally, I developed this with version 1.1 of QGIS and tried
testing it with 1.0.2 and it didn't work there, so I assume that
something wasn't available in the API for version 1.0.2.
Bob Bruce
Here is the report that I made earlier:
Something strange is happening, a plugin that was working before has
stopped working for me now. I recently set up a new Windows XP system
(which has been fully patched) and then installed QGIS 1.0, 1.1.0 and
1.2 along with the libraries using the OSGEO4W installer. It has been
two months since I have been using this plugin but I don't suppose that
the API has changed in that time?
When I run my plugin in QGIS 1.1.0 (Pan) the Python code in the plugin
enables the mouse clicks on the canvas to be captured and when I move
the cursor on the mapcanvas I see a cross-hair cursor but as soon as I
click on the canvas a Windows dialog appears with the message "qgis.exe
has encountered a problem and needs to close" and QGIS crashes. The slot
function never seems to be entered because the QMessageBox at the top of
it never appears before the crash. Shown below is a snippet of my Python
code in which I have added some calls to QMessageBox in the function
setUpRubberBanding and these get called but the message box in
setClipWindow never gets called before the crash.
What would be causing this QGIS crash?

Hi there Bruce,
Try to make the SIGNAL signature match the C++ signature as that is what
PyQt will try to match. Specifically you are using Qt.MouseButton (the

Try:
QObject.connect(self.emitPoint, SIGNAL("canvasClicked(QgsPoint &,\

Hope that gets you going.

Subject: [Qgis-user] Need Help on Coordinate Capture in Python Plugin
Hi:
I am writing a python plugin to clip images to a user selected
rectangle and am stuck at the point where the plugin gets the
coordinates from mouse clicks. Here are some code snippets from my
plugin:
-
-
-
# connect QGSMapCanvas mouse click event to the rubber band clip
window
# function
self.mapCanvas = self.iface.mapCanvas()
self.emitPoint = QgsMapToolEmitPoint(self.mapCanvas)
self.mapCanvas.setMapTool(self.emitPoint)
QObject.connect(self.emitPoint, SIGNAL("canvasClicked(QgsPoint &,\
Qt.MouseButton)"), self.setClipWindow)
def setClipWindow(self, point, button):
QMessageBox.information(self.iface.mainWindow(),\
"ImageClipperDlg Mouse Click Event"," Here are the
coordinates ")
I have tried many variations of the argument lists but I cannot seem to
get the method/function setClipWindow to be called. Can someone see what
I'm doing wrong?
Thanks,
Bob Bruce
