some generated captchas are pretty hard for humans

[michielbdejong]

while testing this, it generated 'ebm0mo' which looked a lot like 'ebmomo'. i'm not really comfortable with putting up such difficult captchas to our customers. is there a way to configure which letters it should use?

also, i would like it to for instance keep a slightly bigger margin between the characters and the image edge. in general, i would like to minimize the chance that a human fails the captcha :)

Text:

You can see here https://github.com/wearefractal/captchagen/blob/master/lib/main.coffee#L9 that we allow text coming in from the outside. You can randomly generate your own text and pass in {text:"the captcha"} to .generate if you only want to use certain letters

Margins:

I've just pushed a change that will allow you to configure the font (default is sans)
