You'll need to have a UNIX-compatible system and you need to use other tools to actually get the Eden data out of your iOS device, and to convert the PPM map image into JPG or PNG or GIF. But there is no jailbreaking required, or anything else that's "unauthorized".

Can you make a video how we can make our own Map? I haven't time to read the complete time. It would be amazing if you can do that :) .
I'm a bit too busy programming to be making videos. The Rubik's Cube videos I made took weeks. And I don't have Ezvid, Fraps, Hypercam or anything like that, so I'd be pointing my phone at the screen and it would look really stoopid ;-P.
Here are the written instructions. You can read it and ask me to explain the parts that don't make sense.
This should work for any system with a UNIX-like shell and the basic commands (including a C compiler), such as Linux, MacOS X, or Cygwin. (CygWin is a free UNIX system that runs under MS Windows).
Make a new directory where you'll do your Eden mapping work.
Go to mrob.com/pub/vidgames/eden-file-format.html and look at the "Source Code" link to get the file "la-map.c.txt". Save the file in your new directory, with the name "la-map.c".
Compile it with a command like "cc la-map.c -o locus-amoenus"
Run Eden, go into a world, save, and quit.
Use iTunes to back up your iPad (or iPod Touch etc.), then look in "C:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup". If you're on a Mac, it'll be "(your home)/Library/Application Support/MobileSync/Backup". Look for a big, recently-modified file. That's probably your saved Eden game. Instead of iTunes, you can also use a utility like iExplorer to get the saved game file directly out of the device. Once you find the saved game data, copy it into the directory you made in step 1.
Run the program with a command like: "./locus-amoenus 17215923032.eden fmg q", where "17215923032.eden" is the name of the saved-game file. It will produce an output file called "World_1.ppm", where "World_1" is the name of the world (with spaces changed to '_' and quotes changed to '.'). PPM is an image file format.
Use ImageMagick or another image conversion utility to convert "World_1.ppm" to JPG or PNG or whatever format you want.
There are other functions available in this program. Leave off the 'fmg q' part of the command, and you'll see a command prompt like "locus-amoenus command (? for help) >". Enter '?' to see a list of commands.
