Composite transformation with alignment : shift and rotate user interface

Post by pierrelabreche »

Suggestions for usability :

1. Allow user to shift the overlay by dragging it using the mouse, from anywhere inside the overlay frame. -- This would be very natural for a user, in addition to keeping the ability to move the alignment points.

2. Allow user to rotate the image relative to a user-selected pivot.

3. During manual alignment, allow the frame representing the overlay to be filled with a transparent version of the overlay image

1. To move all the alignment points at once, hold down both Ctrl and Shift while dragging

Will consider 2,3 for future versions.

Is there a rationale for holding down Ctrl and Shift while dragging ? The operation would certainly be easier without.

In PWP 7, there was an option for multi-point alignment and Shfit and Ctrl added and removed alignment points. I want to keep open the option to re-implement this in PWP 8.

How about allowing dragging when no key is held down while the left mouse button is held?

That could lead to accidentally moving all the alignment points if you just missed clicking on a single one you were trying to move.

I could possibly make Shift-click drag all of them and then if I ever re-implement multipoint alignment, Ctrl-Shift click could also work.
