[FWTools] Starting FWTools

[Richard Greenwood]

I am confused about your question. You said "convert a .ecw file to a tiled
tiff file" but you also said
"redo the .ecw with tiling". So do you want to read or write an ecw?

If you have an existing tiff and just need to change it to a tiled tiff
and/or build overviews then that is pretty easy because you can skip the
ecw part. If you need to write an ecw that's harder. If you can not get the
FWTools working on your distribution then you will need to build gdal with
ecw support, which requires getting the ecw sdk. Licensing has gotten
tighter on the ecw format and it may be hard to get the sdk now.
