Auto contrast stacks with SHIFT key - want it back

[Peter Antal]

Dear all,

This is mainly a question for developers of imageJ:

Prior to version 1.52d, there was a possibility to auto contrast the slices of a stack by holding down the SHIFT key while stepping forward/backward in a stack.

In newer versions, it is not possible anymore. You have to switch on the "Auto contrast stacks" checkbox in the appearance options.
I used the SHIFT key method a lot but not always, and always changing a checkbox in the options dialog is much more cumbersome.

In the imageJ changelog (https://imagej.nih.gov/ij/notes.html) there is a note for version 1.52d:
"Thanks to Mark Histed, when the shift key is down, the display range is no longer changed when stepping forward/back in a stack."

So this change in behavior was intentional, not a bug. Why did you decide to change this? Is it possible to bring the SHIFT key (or other hotkey) method back?

---
Another technical thing:
Is this mailing list also for contact with developers, so for e.g. bug reports?
Is it completely separated from the contact methods available on http://imagej.net, such as bug reports page (http://imagej.net/Bug_reporting_best_practices) or image.sc forum (https://forum.image.sc/)

Thank you!

Regards,
Peter

Hi Peter,
I do not know the reason for the change, or wheter it will be reverted.
However if the problem is that you need to change the checkbox, here is a
possible solution: you can record setting the checkbox and add the recorded
macro line to the StartupMacros.txt file. That way it will be set when you
start IJ.

In my setup case the line recorded for the Appearance submenu is:

run("Appearance...", "auto cancel menu=14 16-bit=Automatic");


The "auto" switch tells IJ that it should be checked.
Hope it helps.
Cheers

Gabriel

Hi Gabriel,

Thanks! This partially resolves my problem, since in most cases I use the auto contrast setting. However, in some cases I have to quickly change between the two modes, so the hotkey method would be beneficial.

Thus, the question for developers remains: Could the change be reverted in a next version of imageJ?

Thanks!

Peter

OK, some other ideas:
What about assigning macros to some hot keys to which switch the autocontrast
on and off?
I wonder it if is also possible to create just a one button macro in the
toolbar that toggles the status of the autocontrast setting.

Similar to the method to get around this problem.  With the <Ctrl> I not implemented in FiJi to load macros from the macro editor and nobody else sending a good method, setting up a function key to load the macros from disk is the workaround.
