I have some suggestions about the global flag in the Set Scale dialog.
Currently, setting the "global" flag not only re-scales (in pixels
per unit) all images that are open, but also those that will be
opened in future. For example, if I send a scaled TIFF image to some
else who's global flag is on, it will be silently re-scaled.
There is also the danger that the scaling of a whole series of TIFF
images may silently
be spoilt after batch processing, if someone has earlier activated
the global flag.
The "scale global" flag remains active until you reset it or re-
launch ImageJ.
Another item is the behaviour of the "changed" status and the
"Revert" command:
- Changing the scale does not mark the image as "changed".
- Changing the scale of an existing TIFF image, and then choosing
menu "File>Revert"
does not restore the old scale (independent of the global flag).
I liked the way NIH Image handled this:
There was a "Propagate" command, where you could propagate scale and
calibration
to all open images. It had no future effect, and it was easy to
understand.
Some derivatives also could propagate the Roi.
