[Qgis-user] click on raster outline to make it visible

[Michel Stuyts]

It looks like the \r in the path is interpreted as a carriage return and the \t as a tab and so a part of the path is missing for GDAL. Maybe you can try to replace the \ by \\.  

Info on Escape Sequences: 
	- http://python-reference.readthedocs.io/en/latest/docs/str/escapes.html 
	- http://en.cppreference.com/w/cpp/language/escape

I also notice a mix of \ and / in the paths. I don't know if that can cause problems.

Hello,

I have defined an action with the following python code:

from PyQt4.QtCore import QFileInfo
fileName ="[%"Locatie"%]";
fileInfo = QFileInfo(fileName);
baseName = fileInfo.baseName();
qgis.utils.iface.addRasterLayer(fileName, baseName);

The problem that I’m having is that the string stored in the Locatie field gets interpreted.
In a path name like
F:\Ingelmunster\riolering\infraxscans\tif2/331-Meulebekestraat_Leon_Bekaertstraat_Mandesweg_GP_deel2.tif
\t creates a tab spacing and \r removes a character.

Ongeldige Laag: GDAL provider Cannot open GDAL dataset F:\Ingelmunster iolering\infraxscans
if2/335-Meulebekestraat_Lammekensknokstraat_Bollewerpstraat_Bekaertstraat_Ringlaan_GP_deel3.tif:
`F:\Ingelmunster iolering\infraxscans
if2/335-Meulebekestraat_Lammekensknokstraat_Bollewerpstraat_Bekaertstraat_Ringlaan_GP_deel3.tif'
does not exist in the file system, and is not recognized as a supported dataset name.

How can I load the rasterfile with the filename that is stored in the Locatie field into qgis?
Is there any comprehensive tutorial on actions?

Regards,
