I develop a QGIS plugin that includes a step of georeferencing. I want to open the Georeferencer from QGIS and to load an image with its path when I click on a PushButton.

I found this topic : Open Georeferencer and load raster at startup

which seemed to conclude that it's not possible to pass an argument when opening the Georeferencer (and the proposed code doesn't really work for me) :

self.iface.mainWindow().findChild(QAction, "&Georeferencer").trigger()
for x in self.iface.mainWindow().findChildren(QMainWindow):
    if x.objectName() == 'QgsGeorefPluginGuiBase':
        for y in x.children():
            if 'mActionOpenRaster' in y.objectName():
                y.trigger()

I got the following error : AttributeError: 'NoneType' object has no attribute 'trigger' so "&Georeferencer" surely isn't the good attribute to open it.

It's been answered for QGIS 2. Is there any way to access Georeferencer window from QGIS 3 interface and pass an image as input?

I looked at Processing toolbox and the Georeferencer is not part of it.

To open Georeferencer window in QGIS 3:

iface.mainWindow().findChildren(QAction, 'mActionShowGeoreferencer')[0].trigger()

To open "Open Raster" dialog

iface.mainWindow().findChildren(QAction, 'mActionOpenRaster')[0].trigger()

  • Thank you. Do you know how I could directly open a raster with its filepath ?

  • I tried, but I couldnt find a way. Feb 11, 2022 at 14:38
  • Is there a way to run georefencer without interface ? I mean, with all parameters for the transformation, with the layer and the GCP file ?

  • your solution works under unix but I get an error with QGIS 3.4 on Windows. The mActionShowGeoreferencer action is not recognized. On this version, Georeferencer is still a plugin to install manually. Is there a link with it ?
