User interface suggestion : Distorsion (e.g. Thin Plate )

[pierrelabreche]

Finding : Using the display input window for placing control points : When the control points are located near the edge of an image, for fine out-of-frame displacements, it is impossible to zoom and to an area so as to display a small stretching vector pointing outside of the image frame.


Suggestion : unlock the display input visible area so as to allow zooming out-of-frame.

This would be difficult to implement -- I suggest adding a border to the image which you can crop out after doing the Distort.
