Thank you very much for all the advice. It all looks like fun things to do with Julia, especially as a learning exercise. I think I’m leaning towards leaving it as simple as possible, add a few options for exporting graphics (png, eps, pdf, svg…) and let people go nuts if they want something more. But I’ll think about it more.
I’m surprised you tell me to export less things, I thought I was being minimalistic already ^^
But thank you, I’ll consider your advice.
As for ErrCorrLevel and Mode, I love type programming too much to give them up (I’m a Haskell kind of guy). I really enjoyed combining multiple dispatch and types to define the different encoding functions.
Thanks again for your feedback!
