[ImageJ-bugs] [Bug 1019] Align image by Line ROI results in Java error

--- Comment #1 from amc910 at bham.ac.uk ---
As an update, I've just tried to restart FIJI and run the Align by line ROI
plugin on the sample images, and it has worked ok.
After some poking it looks as though the exception comes about when there are
more than two images open, that is more images open than those you wish to
align.
The order the images are opened also seems to be an issue.
If I open boat.gif(1), bridge.gif(2) and Dot_Blot.jpg(3), I can align 1 and 2,
but both 2 and 3 and 1 and 3 throw up another nullpointer exception.

Aligning 2 and 3 gives the same

at Align_Image.align(Align_Image.java:139)

error, but 1 and 3 gives

at Align_Image.align(Align_Image.java:141)

These errors also seem to stop if I bother to put a line ROI on the third image
not being used, and just ignore it from then on.

So, this bug is now workable, but not ideal (especially if you don't know the
fix)

Cheers,
Angus
