Displacement items are vectors that describe the required distortion of other vector or raster data, using known control points. A collection of Displacement items is used to define a Rubber Sheet item.

Displacement items are created using Displacement


  • Closed: _closed&
    Does the geometry of the item form a closed loop?

  • Geometry class: _classGeom$
    The C++ class used to store an item's geometry. This is handled automatically. You can see what precision an item's geometry is stored with by recognising the geometry classes.

  • Number of vertices: _np&
    The number of vertices in the item's geometry.
