How can I create an ICS image from another program?

1. In the foreign software, save the image in binary from, for example to foo.raw. If this is not possible try saving to a fixed header format and strip the header.
2. Create an image in the Huygens System of exactly the same dimensions and microscopic parameters as the image you have saved in binary form. Save it in the default ICS format, for example foo. It creates the foo.ics/foo.ids file pair.
3. Rename foo.raw to foo.ids. This over-writes the original foo.ids but you don't need that any more.
4. Open the foo.ics/foo.ids ICS file pair in the Huygens Pro or Huygens Essential.
