I am new to the QGIS python console. I am trying to load a raster layer from the console, set the crs and a specific style from a qml file.

layerPath = os.path.join(raster_dir,raster_name)
fileInfo = QtCore.QFileInfo(layerPath)
baseName = fileInfo.baseName()
layer = QgsRasterLayer(layerPath, baseName)

I would like to set up the projection info and then load it to QGIS

QgsMapLayerRegistry.instance().addMapLayer(layer)

I do have a grey raster on the windows. How can I set up the qml file to load ?

Thanks for your help

use QgsMapLayer::loadNamedStyle

uri = "/home/user/style.qml"
layer.loadNamedStyle(uri)

    Thank you for your help, However I cannot manage to get it working.When I run the following command uri = "file:///home/renaud/palette.qml";layer.loadNamedStyle(uri) I get the error message : Style not found in databased. Thank for your help ? How do I jump line in this post ? – Renaud Jun 06 '12 at 09:37
  • looks like theUri is a bit misleading - using the plain filename should work (ie. /home/renaud/palette.qml) – jef Jun 06 '12 at 13:25
  • Thank You, It is working fine now. One more time, keep it simple is the best way ! – Renaud Jun 07 '12 at 17:53
