Hi Jahannes and Cam,
I took the liberty of tinkering and have added the class imports required.
I'm pretty inexperienced in both Java and Github, but I think I've suggested a change to that file.
Let me know if I've gone wrong somewhere.
Thanks,
-Lachie
PS: Incidentally, shift-click isn't opening the script editor for me, that would be most useful.

The reason is the (ab)use of auto-imports. It is my fault, really, for not
seeing how big this project (or better: this ecosystem of projects) was
going to be. In the early days of Fiji, it looked like a good idea to
special-case two projects and auto-import all of its classes, but nobody
else's classes.
It is almost needless to say that there are a *lot* of other projects now,
all of them important, most developed quite actively, and auto-importing
all of them would simply result in conflicting class names, and favoring
some over others would be less than intelligent, given that nobody can
really see what the future brings.
Again, it was entirely my failure to see the so-called "technical debt" of
establishing auto-imports.
To avoid accruing even more technical debt, I decided that auto-imports
need to be deprecated. I was aware that the users of the few "special"
projects would not be happy about that, but in the interest of the bigger
ecosystem, there was simply no alternative.
In your particular case, the script at
https://github.com/fiji/fiji/blob/master/plugins/Scripts/Image/Adjust/Scale_to_DPI.jsneeds adjustment: it uses ImageJ 1.x classes without importing them
explicitly.
If you find the time, it would be awesome if you could Shift+click on the
Scale to DPI menu item (which will open the script editor; this is one of
the many magic functionalities that few users know about because it is not
*quite* intuitive a user interface :-)) and insert all the required
importClass statements, e.g.
importClass(Packages.ij.IJ);
at the top, then share the fixed script with the ImageJ community.
Ciao,
Johannes
P.S.: If you do not have time to do that, do not worry. We will hopefully
eventually come around to fixing all the scripts, but we will have to work
a bit more on other things, including the Add import command in the script
editor, also something that unfortunately has to take a back seat because
of higher priority projects that need to be addressed first.
