[gdal-dev] world file to world file

[Michele Zanin]

Dear gdal experts,
  i'm very happy with gdal because it solved a lot of difficult
situations for me, but this time I'm not able to find the right
sequence of operations to reach my goal.

This is the problem.
I have a standard (=not geotiff) tiff image and its corresponding
world file using projection epsg:3003, something like:

name.tfw
1.00000000000000
0.00000000000000
0.00000000000000
-1.00000000000000
1615240.50000000000000
5139639.50000000000000

My goal is to  create with gdal another world file for the same tif,
using a different projection, in my case epsg:4326. An example
(numbers are from another image):

another.tfw
0.000167584405076
-0.000000478207876
-0.000000240088571
-0.000115295080174
11.689665492171006
47.091567061470897

It should be not difficult to write a program to do this
transformation, but before starting to write it myself, I think it's a
good idea to ask you for a simpler solution, maybe using a combination
of standard gdal utilities.

Thank you very much!
