[Mapserver-users] generating world files

[Lowell Filak]

Another possibility, because you appear to already be using some flavor of Mapscript, is to take the current upper left of the mapextent and use that for the tfw origin then use the mapextent->maxx - mapextent->minx / image size, ie. (512000-511000)/600=1.666666667 and then use 1.666666667 as the x pixel size and -1.666666667 as the y pixel size to create your own tfw file:
1.666666667
0
-0
-1.666666667
511000
300000
