Switching between two images

[NorthwoodsBill]

I am working my way through Adam's tutorial on the Fabian Neyer star removal method and he talks about blinking to switch views between a mask and the image beneath it.  I can't seem to figure out the keyboard shortcut.  Could someone please help?

Yep! (CRTL+PGDN)

 I have a tutorial that demonstrates 5 or 6 different ways to blink images/views. This is the one I use most often.
I do not know the reason for it (haven't studied the forum)- but blinking views sure seems like a powerful thing to do.
For example if I wanted to show the evolution of a mask via different parameters... I might want to blink three or more masks (and then do pixel math accordingly).
Or perhaps I need to blink a set of views that represent an image at different points along the processing timeline (history states). And of course, just to simplify
the comparison of two views- a blink tool would be great.

If a blink tool isn't in the cards for PI, what might be equally useful is for a single method to match two views in terms of their window dimensions, position in image, and zoom factor. Dragging and dropping is OK but only works well if you are dragging from right to left with the right view being on top. This is the short distance and does not require worrying about the overlap of images (using the shift key).

Furthermore, if the images are *already* matched in window dimension, position and zoom... and you change one of these elements in one image- a keyboard press to have the other image matched with the new settings without dragging and dropping would help. Even better... something to "connect" the views temporarily so that any change in one is reflected in the other. Since the images are on top of one another exactly..you need to unalign the window, re-drag/drop, and realign.

If I am missing this feature- *please* let me know! Of course, just having the blink tool blink views takes care of everything.

Hi Adam,

Dragging and dropping is OK but only works well if you are dragging from right to left with the right view being on top.

While you are dragging, hit the shift key to bring the image window under the mouse cursor to the top of the window stack. This allows you to drag anything over any open (and not completely overlapped) image.

...a single method to match two views in terms of their window dimensions, position in image, and zoom factor.

This is already planned for implementation, maybe in the next version, which I'm going to release soon. There will be more drag and drop actions, including a fast way to copy STF settings between two views.

something to "connect" the views temporarily so that any change in one is reflected in the other.

Something similar to this has been also on the drawing board for some time. The implementation of this feature is not trivial, but I agree, it would be really powerful. I'll try to find time to return to this subject, thank you for pointing it out.

Thank you Juan.
Yes, I understood the shift key bit- it is just the real estate you have to travel (on a crowded screen) that is sometimes tedious.
Thanks of the update on potential software evolution.

Thank you.  Learning - one baby step at a time.....
