Dear Gwyddion Devleopers,I would like to make a request for a feature in
Gwyddion. It is really a fairly simple (I hope) change to a current feature.
Currently, researchers in my group use the "Extract Profiles" Feature, to
measure step heights, a lot. When you select a profile, you have the option of
changing "thickness" from 1 to 128 pixels. I guess what this does is to (mean)
average a number of lines, it says in the documentation:
"Profiles can be of different “thickness” which means that more neighbour data
perpendicular to profile direction are used for evaluation of one profile point
for thicker profiles. "
This is really useful. But the problem is that it's not very visual, because
the user cannot see where the lines being averaged are. It would be great if
when the "thickness" is more than 1, instead of a line, a rectangle, showing
where the lines being averaged are on the image. THis way, we can maximise the
"width" of the profile, while avoiding unwanted "features".
Ideally, the rectangle would also have some clear indication of which axis is
along the profile length (e.g. a central line with arrowheads), because when
you have "drawn" a square by this technique, it is easy to get confused and
think the averaging axis is the profile length axis, etc.
Thanks once again for the great software!pete.
