[Geotools-gt2-users] WorldImageReader ... jpg = good, jgw = bad

[Jody G. <jga...@re...>]

Figured it out; the code expects the initial file to be the jpg, I was 
opening the jgw file (the layer of insulation between uDig where I was 
stealing code from; and raw geotools led me astray).

That said I ran out of memory with the defaultVM size ;-)
