In case you wondered what that post from earlier today was all about, perhaps a picture will help:
This envelope came in the mail yesterday. I don’t know who put me onto this mailing list, but I’m pretty sure it’s related to the work I’ve done over the last few years supporting the NITF file format, whose users are an interesting lot. They don’t really like to talk about what they do or what they keep in their files: secret stuff mostly.
I’m not one to judge. I’ll just say that I’m very glad that I was also responsible for adding support for the DICOM medical imaging format to MATLAB.
