I have produced the ftw file as you suggested:
10.0000000000
0.0000000000
0.0000000000
-10.0000000000
584018.5625000000
5147058.5000000000
but why the values are different from gdalinfo?
gdalinfo img.tif | grep Origin
Origin = (584013.562500000000000,5147063.500000000000000)
The world file contains the coordinates of the center of the upper left
pixel of the map.
gdalinfo gives the coordinates of the upper left corner of the map.
You'll notice that the difference is equal to half the pixel size.
Have you read the Wikipedia article at
http://en.wikipedia.org/wiki/World_file ?
