[Qgis-user] creating a python plugin to autopopulate some of the Georeferencer properties

[Eric Goddard]

Hi Nicolas,

Thanks for the feedback. The script solution won't really work for us since
we don't have pre-existing GCPs to use in the scripts. We need to use the
georeferencer so we can place and make adjustments to the GCPs.
