[gdal-dev] Formats question (was Re: JPEG2000 question/issue)

[Nidel, Mike]

That was what I was looking for, thank you.

Now a new question, is there a way to remove formats from the
build entirely? Obviously there is for formats that require
external libraries, they just don't get uncommented in the
nmake.opt. But what about, for example, disabling NITF at
compile time? I would actually like to disable ALL gdal formats
except MrSID, but NITF causes a particular problem for me
because I already have an NITF reader and there is a conflict
in the way I'm loading the readers.

thanks,

Mike
