The Perspective tool
This tool is used to put the image or current selection into perspective. A modification of the four corner coordinates of the image is sufficient to obtain a convincing effect. You may or may not fill the screen with the current image (see examples below).
Here again, the same system as above is used (Preview then Apply). Use the Reset button to reset the settings. The AntiAliasing popup allows to choose the precision with which the image contours will be smoothed. The result is similar to the Transform Tool.

The blue line that appears on the screen during setting is the horizon line. You may move the two vanishing points as you wish to set the perspective.
