Hello Paul It is probably easier to do this kind of correction with tools other than hugin.
Photoshop has 2D perspective correction as an option on its cropping tool. As you are on Linux, you don't use Photoshop, but I expect the Gimp has something similar. Basically you draw a stretched rectangle on the image and the program gives you a real rectangle containing that part of the image. Very easy when you have a picture of something rectangular. You can also correct perspective with PanoTools. This is a little more abstract as you have to specify angles of rotation of the original picture plane around its horizontal and vertical axes, but works just as well. I have only used the photoshop plugins (which I believe also work with the Gimp) for this, but one of the command line tools does it too.
