Bigger-/Change Captcha Codes

[theLazzor]

We often have problems reading captcha codes. In size are ok, but you have to generate several parts because they are not good enough to read. Is it possible to "swap" the captcha codes?

A few notes after research (without testing etc.):

captcha options explained:
https://django-simple-captcha.readthedocs.io/en/latest/advanced.html

settings file in seahub (hot linked to a captcha setting):
https://github.com/haiwen/seahub/blob/master/seahub/settings.py#L692

without having any more knowledge it might function to play with the settings from the first url und set them at around line 692 in the mentioned file. afterwards restart seahub and see results.

(if you come to a better solution, please paste your settings here with a screenshot of a generated captcha - would be nice to bring it upstream, wouldn't it?)
