Rotate / Zoom
Ctrl + Shift + Z
The command to open the Rotate/Zoom dialog can be found in the or invoked with
Roll / Rotate
The active layer can be rotated about the Z axis by clicking and dragging dragging the outer ring of the
The Z axis is aligned through the center of the Roll control "globe" and the reticule. If the Roll control is realigned so the reticule is pointing South East, the Z axis will also be aligned to the South East. Rotations using the outer ring will appear to be centered about this axis.
The Center of the Roll/Rotate control allows rotations simultaneously about the X and Y axes. The control can be clicked and dragged as can sliders two and three respectively. Values can also be typed directly into the numeric input boxes.
The third slider is perhaps the easiest understood. It controls the apparent tilt of the image from zero (front on) to 90 degrees (side on)
The second slider determines which compass direction the reticule faces. Zero is due East, 90 degrees South, 180 degrees (both + and -) West and -90 degrees faces North. The action of the second slider is most obvious when the third slider is non-zero.
Panning is the action of sliding the image in the same plane as the rest of the layer. Click and drag the control or use the sliders to move the layer around the canvas.
The upper Pan slider controls movement horizontally. The lower pan slider controls movement vertically.
This control expands or contracts the layer. Higher zoom settings increase the size of the contents of the layer. Smaller values shrink the contents of the layer.

Using the Rotate/Zoom controls allows an image to be tilted and transformed as if it were at an angle to the viewer. It is relatively easy to create the illusion of depth or perspective using these tools.
