Python plug-in which lets you rotate an image and apply a perspective correction by setting a path.
Perspective uses three points and rotation needs two.
Rotation will detect whether the line you are starting from is near vertical or near horizontal and apply a rotation that get to the closest orientation.
This script will add an improved perspective shadow to your image objects, text, shapes, or whatever.
Filters/Light and Shadow/Perspective Advanced
This script creates a reflection of the current image with optional perspective.
User inputs for rotation, distance and camera height.
Set rotation and distance to 0 to create a reflection without any perspective.
