[Gimp-user] Unified transform Tool When Zoomed In

[programmer_ceds <forums gimpusers com>]

Firstly I would like to say that the Unified Transform tool is a brilliant idea
- much easier to use than a combination of the separate tools and only one round
of interpolation at the end.

There is, however, a problem if you are using the tool on a reasonable sized
image and want to zoom in to fine tune the transformation - the control points
disappear and the only available operations are moving the whole image or moving
the centre of rotation (unless I am missing some way of selecting the other
operations).

With the individual tools (rotate, perspective, shear etc.) it is still possible
to make the transformation even when zoomed in.

One possible solution would be use "View/New View". the additional view that
results can be zoomed independently to the main/original view and can be used as
a magnifier for part of the image. However, for this to be a solution the
additional view would need (possibly as an option) the ability to reflect the
state of the main view in real time - currently it is only updated on the
completion of an operation - for example a line drawn with the pencil only
appears in the additional view when the mouse button is released, whereas the
part drawn line appears immediately on the main view. Similarly the effects of
the Unified Transform tool only appear when the operation is completed.

Adding this real time updating of the New View would also provide something that
would satisfy Enhancement Proposal: Add a temporary magnifier

A second solution would be to always display the control points of the Unified
Transform tool no matter how far in the image was zoomed but this solution (if
possible) would have a less broad application than adding the live view (option)
to the New View.
