The Rotate paned lets you rotate and tilt the foreground or background image.
The rotation options are:
Here is a image rotated +90. Notice how the image does not fit anymore. That is because the image is now wider then it is tall so we would need to go back to the scaling window and fix it.
Flipping an image can be very useful. You can see that the fire now needs to go on the other side of the princess. We could move it there is we had enough background or we could flip the background also.
Here it is with the background flipped (I moved it in the scale panel to get it in the correct place)
Here it is just moved.
The tilt control is a bit unusual. Tilting would normally be a slider but it turns out that the tilting process combined with the green screen removal process makes the response to the slide so slow that you have the feeling that the slider is not working. To tilt to the right simple select one of the right radio buttons. The farther you go to the outside the more tilt there is.
The tilted image must fit inside the bounds of the original image. This has the effect of making the tilted image smaller. You can fix this and the positioning in the scale panel.
Here it is fixed by the scaling panel
