This extension changes the z-order of objects based on their position on the canvas. A variety of parameters control how the restacking is done. The Restack Direction is set by a drop-down menu in the Restack dialog. Options include: Left to Right, Bottom to Top, Right to Left, Top to Bottom, Radial Outward, Radial Inward, and Arbitrary Angle:. In the last case the angle is given in the Angle entry box where the angle is defined counterclockwise with zero corresponding to left to right. The last two parameters control which point of an object's bounding box is used in the restacking process.
