getworldfilename

Derive world file name from image file name

Syntax

worldfilename = getworldfilename(imagefilename)

Description

worldfilename = getworldfilename(imagefilename) returns the name of the corresponding world file derived from the name of an image file.

The world file and the image file have the same base name. If imagefilename follows the “.3” convention, then you create the world file extension by removing the middle letter and appending the letter 'w'.

If imagefilename has an extension that does not follow the “.3” convention, then a 'w' is appended to the full image name to construct the world file name.

If imagefilename has no extension, then '.wld' is appended to construct a world file name.

Examples

Given the following image file names, worldfilename would return these world file names:

Image File Name

World File Name

myimage.tif

myimage.tfw

myimage.jpeg

myimage.jpegw

myimage

myimage.wld
