"Drag to Move the Picture" will move 1. 2. and 3 to nonsense positions

[jidanni]

When clicking the "Drag to Move the Picture" etc. in the left panel, mark 1, 2,
and 3 temporarily disappear.
And it turns out they will lose their positions... and end up translated
to nonsense positions.
Actually they should stay always in view, and they should stay pinned to
their spot on the picture during the process.

Yes. I am saying that if any time during the video, the user clicks the button that is the one just above the green arrow button, and then moves around his picture, his three points will (unfortunately, needlessly) lose their bindings to where they were on the picture, and become nonsense locations.

One might say it is his own fault for clicking it. But then again it is in active clickable color, not greyed out.

Replying to jidanni:

Yes. The handles disappear.

And it turns out they will lose their positions... and end up translated
to nonsense positions.

This could not be verified here. All three handles hold their positions on the moved picture. Are you sure that you did not have used the "Drag to shear the picture" button? Using the shear button images here go elsewhere with one move.

Actually they should stay always in view, and they should stay pinned to
their spot on the picture during the process.

Yes, that would be an enhancement.

The question is if it can be proven that the handles jump to nonsense positions. As said, I wasn't able to reproduce this.

Be sure to test with the combined "Drag to scale picture in x y axis" button.

1. With green arrow make points 1, 2, and 3.
2. Now optionally click the red arrow.
3. Now click "Drag to scale picture in x y axis", and drag...
4. Now click the red arrow again.

Notice when the three points reappear,

• they are no longer where they were on the photograph,
• nor are they where they were even on the base map.

At least the one on the northeast is still in the northeast etc.
i.e., their *relative* positions in regard with each other is the same... for whatever good that is...
