Description:

 Apply applies a rubber-sheet to graphics using the current Rubber Sheet item.

This command will appear greyed until a Rubber Sheet item has been made current. (See the associated commands: Displacement, Create and Set Transform.)

When a Rubber Sheet item is current, select the items to be distorted, then this command, and the necessary transformation will take place.

When you use this command, each vertex in vector geometry is transformed according to the algorithm, so no new vertices are created in the items.

Each pixel of raster information (e.g. Bitmap) is transformed according to the chosen algorithm, and the resulting Bitmap item pixels are aligned to the X and Y axes of the Bitmap item's coordinate system. If you choose the "Linear Patch" algorithm then any pixels outside all triangles are ignored, and the output image will be clipped.
