IWorldFileExport Interface

Provides access to members that export Georeference information to a WorldFile.

When To Use

IWorldFileExportinterface output the internal georeference information of a raster dataset to a world file.


Name Description
Method Write Creates a World File.

IWorldFileExport.Write Method

Creates a World File.

Public Sub Write ( _
public void Write (


For GRID format or datasets that get their georeference information from a world file, IWorldFileExport:Write method has no effect.

Classes that implement IWorldFileExport

Classes Description
RasterDataset A representation of a raster dataset on disk.


The interface is used to write the internal georeferencing information of an image to a world file. The name of the word file is as same as the image file name except the file extension. The extension of the world file is the first letter and third letter of the image file extension plus "w". For example, if the image name is "redlands.tif", the world file of the image will be "readlands.tfw".

The world file stores an affine transformation in the following form:A (x cell size )D (rotation term)B (rotation term)E (negative y cell size)C (x translation term in map coordinate)F (y translation term in map coordinate)

which represents the following transformation:x1 = Ax + By + Cy1 = Dx + Ey + FThis interface is not supported by a RasterDataset instance from an ArcSDE geodatabase or a File geodatabase.
