Drawing a gauge using GIMP

Steps to create a speedometer gauge. It uses layerfx.2.8.py script. Once it has been downloaded, it should be copied at ~/.gimp-2.8/scripts folder giving execution permissions (chmod u+x layerfx.2.8.py ).

indicador00.xcf is a free version of previous tutorial.

Exporting from GIMP to QML

Download qmlexpoter.py at ~/.gimp-2.8/plug-ins folder giving execution permissions (chmod u+x qmlexpoter.py ).

Restart GIMP to have the export command added to the File menu. Choose File > Export to QML to export GIMP design to a QML file. In the Export Layers to a QML Document dialog, enter a name and location for the QML file, and click Export.
