Since you are using Linux, you may be interested in a tool I wrote a few 
years ago :

You can compile it manually by a command such as :
g++ -o ecwhed -l pthread  ecwhed.cpp /usr/lib64/libecwj2.a

( The standard procedure ./configure; make; make install is not working 
anymore. If you know the autotools, may be you can fix it).
