QGIS 2.18 on Linux Mint 18.1 64 bit
I recently had to clean install my OS & QGIS etc. Whilst it's mostly
working, the raster georeferencer is unusably slow most of the time.
I thought initially it didn't like jpgs and pdfs were OK, but it is the
same regardless. On clicking transform, the progress indication window
opens & it will sit there for an indeterminate period (I left it over 30
minutes once). There is a lot of CPU activity across all four cores.
The only way out I've found is to kill QGIS.
If I have the Target Resolution box empty, the result is an image
comprising large blocks/pixels and a wide black component. If I select
the target resolution, I can improve the image (but still unusable)
however, to get anything vaguely usable, the process takes ages as
mentioned above
All my previous installations have been fine & I have never had a
problem with the georeferencer.
Any ideas where to look please?
Many thanks
