Sometimes, after correcting either vertical or horizontal keystoning, so that the lines I want parallel are parallel, I also want to change the vertical or horizontal scaling. That is necessary because the keystoning correction alone may not yield the right scale. If one knows the position of the lens and the actual dimensions of the building, or if one knows the position of the lens and the angle at which the lens axis points, one can calculate the proper scaling, but, while the lens position may be in the exif info, the other information is not. So one has to correct the scale by eyeballing it.
I can't find a darktable plugin to do it.
