Re: IMAGEJ Digest - creating a fixed line segment and movable im age

[Heeschen, Bill (WA)]

Not sure where this thread is since I get digests, but a comment on
comparing images:

The Paste Control option allows you to copy an image, then paste it
(onto another image or back on top of itself) to view a combination of
two images where the combination is calculated in real time as you shift
the pasted image around.  A little experimentation would allow you to
cut the image, draw the desired line, then paste the image back on top
to accomplish your goal of moving an image around relative to the fixed
line.  I suspect a white or black line would be best, then use the
"Brightest" or "Darkest" option under Paste Control to keep the line
visible at all times.  Adding the real-time profile seems a bit
tougher...

I will guess that Paste Control is one of the coolest "Wow" factors when
demonstrating ImageJ to new users.  It also has a lot of real utility
when trying to compare differences between images.

Eventually, I'd like to be able to compare two images to each other =
using an x- and a y- profile.  I figure it will be easiest to =
incorporate two fixed line segments along with fixing one image.  That =
would allow me to have a constant x- and y- profile of the fixed image =
and I could move the other image and observe it's real-time profile to =
align it with the fixed image.

I guess at this point I'm just trying to take one small step towards a =
much larger solution.

Thanks Bill, I think you're pointing me in the direction I was looking for.  Maybe you could help me out a little more with the Paste function.  I've tried just a right-click Copy, Paste of an image onto itself as well as onto another image, but in both cases, the pasted image just overlays the original image.  You mentioned that I should be able to view a combination that is calculated realtime, so I was excepting the overlaid pixels to sum together.  Am I missing a trivial step along the way?
 
Thanks again for the help,
Robert

Sure enough, as soon as I confirm my last email, I stopped right-clicking and noticed the Paste Controls... option under the Edit menu.  That truely is a "Wow!" factor!
 
Thanks again!
