RubberSheet()

Summary

"Rubber sheets," or performs a mathematical transformation on the coordinates of a geographic layer, and produces a new database using the "rubber-sheeted" coordinates.

 

Syntax

RubberSheet(string layer_bar_set, string db_name, array old, array new, array options)

 

Argument	Contents
layer_bar_set	The layer and the set to be rubber sheeted
db_name	The name of the new database to be created
old	An array of coordinates as they currently appear in the database
new	A corrected array of coordinates corresponding to the old array

 

Option	Type	Contents
Method	String	"TINS" or "Uniform"
World	String	"True" (the default) or "False"
Label	String	A descriptive label for the new geographic layer
Layer Name	String	The name of the new layer in the geographic file
Node Layer Name	String	The name of the endpoint layer in a line geographic layer

 

Notes

• The TINS option triangulates the control points and performs a separate transformation to each facet.

• The World option is set to "False" when the coordinates used are map coordinates.

Example

c1 = {Coord(-92398569,38894200),

     Coord(-92383337,38882221),

     Coord(-92369238,38961503),

     Coord(-92352231,38884966)}

 

c2 = {Coord(-92400654,38885840),

     Coord(-92382696,38870492),

     Coord(-92371033,38961093),

     Coord(-92353033,38874735)}

 

RubberSheet(GetLayer(), "new.dbd", c1, c2,

     {{"Label", "New DB"},

     {"Layer Name", "New Layer"},

     {"Method", "TINS"},

     {"World", "True"}})

 

Error Codes

Error Type	Meaning
Error	The number of points was too small or the rubber sheeting failed
