Well, maybe he wants to embed an emblem or logo in a .sav file.
Something a bit more "professional" than simply distributing a separate
file. I mean, *anyone* can do that!
The trick is encoding the image into a function. Like so:
http://www.acoustics.wa****ngton.edu/~towler/programs/make_imageFunction.pro
Like the header says, there are I'm sure a load of issues you could run
into. I've used this on a number of smaller images and it works but I
would expect this to fail with even "medium" resolution images. Also
you'll want to tweak this a bit as I was working with .png files.
Enjoy!
