When this tool is selected, clicking
in the image will superimpose a grid
on it that you can rotate by dragging
it around. Or, you can select the
rotation angle with the slider or text
area in that "Rotation Information"
box. Clicking on the "Rotate" button
will rotate the picture according to
the grid.
This tool has a bunch of options, most
of which you can ignore. The really
important and clever one is "Transform
Direction".
When the Transform Direction is
"Forward (Traditional)", the grid's
orientation represents what the
picture will be rotated to from its
original upright position. If the
picture is already upright and you
want it to look tilted, that's the way
to do it.
The "Backward (Corrective)" direction
is what you use to fix a picture that
you took with a tilted camera. You
orient the grid so it shows how you
think the picture is tilted. I've
selected that, and oriented the grid
so that it coincides with the tilt of
the bookshelf behind Niobe's head.
Clicking on Rotate will then un-tilt
it.
