Sets the current Rubber Sheet Transformation from the currently open Rubber Sheet item. This method must be used before transforming Raster or Vector data.

The displacement method to use:
SIS_RUBBER_BEST_FIT
Only three of the displacement items are used, so if you have created and selected more than three you will not be able to predict the results.
SIS_RUBBER_LINEAR_PATCH
All the start points of the displacements are triangulated. Only points which lie inside one of the triangles or on its border, are transformed – other points are left unchanged.
This method is most suited to fitting digitised vector data to known positions.
SIS_RUBBER_INVERSE_SQUARE
All displacement items are used to transform every point, but closer displacements have more effect on a particular point than the more distance ones. If a point is exactly on the start of a displacement, it will be transformed to the end displacement.
Points a long way away from all displacements will be moved to the average displacement. Therefore, if the average displacement is zero, the transformation will only have a local effect.
This method is most suited to fitting a scanned bitmap onto existing data accurately.
