Freehand Raster Georeferencer plugin updated for QGIS 3

A few weeks ago, I updated my Freehand Raster Georeferencer plugin for the newly released QGIS 3. I also included a few fixes for some issues as well as new features such as uniform scaling, a new “Georeference with 2 Points” tool (contributed by a user) or taking into account an existing world file. Those changes were backported to the plugin version for QGIS 2 so there should not be any difference between the QGIS 2 and 3 versions. See the updated doc for information.


QGIS 3 was released at the end of February and included quite a few changes when it came to plugin development:

  • The most obvious change was that the version of Python used for plugins is now Python 3. My code was pretty much compatible, except that I had to switch to relative imports and drop the u from strings. I used the standard 2to3 tool to check the code.
  • The second most obvious change was the switch to PyQt 5 (instead of PyQt 4). Again, there were not a lot to changes: Basically, update the imported PyQt modules, as well as change the packages for widgets, now in PyQt5.QtWidgets instead of PyQt4.QtGui. I also had to rebuild the .py fils from the .ui with the pyuic5 tool.
  • I also had to update the metadata with the new QGIS 3 version (qgisMinimumVersion=3.0). I was not sure when I published the plugin for QGIS 3 if the QGIS 2 version would be kept available for users still on QGIS 2, but there was no problem: The QGIS plugin manager shows the latest published version of the plugin compatible with either QGIS 2 or 3, depending on which one is used.
  • Finally there were a lot of API changes. The project has released a list of backwards incompatible changes to help and mostly it was pretty clear what needed to be changed. Here are some more details on a few points:
    • The plugin is based around a QgsPluginLayer and I had to add 2 new classes that were not necessary in QGIS 2: one subclass of QgsDataProvider that needs to be returned by the dataProvider() method of my plugin layer + one subclass of QgsMapLayerRenderer that needs to be returned by the createMapRenderer() method.
    • Checking the visiblity of a QgsMapLayer used to be done with something like iface.legendInterface().isLayerVisible(layer). The QgsLegendInterface class has been removed and replaced by a layer tree API. Now, I am not sure if that is the best way but I performed the checking of the visibility of the map layer with iface.layerTreeView().layerTreeModel().rootGroup().findLayer(layer).itemVisibilityChecked()

The QGIS project has released a tool and some instructions for migrating plugins.

Square des Poètes

The Square des Poètes is a park located right next to the Jardin des Serres d’Auteuil in western Paris. It is dedicated to poetry, with busts of famous poets (Victor Hugo, Théophile Gautier, Alexander Pushkin…) and 48 plaques with French poetry.
