Hello there, i would like to use the "Autolevels" plugins created by Aldo from (Field Of view)... it's work well but only with Flash... but i need it for HTML5. I've PM Aldo and send a mail but no answer, i think he have lots of work... this plugins is 2010...but it's look so interesting to have a good immersion. (Sorry for my english, i'm french...)
I've found the source of the action script... (it's free) :
https://github.com/fieldOfView/krpano_fovplugins/tree/master/autolevels/source/
And i've found an ASC3 (action script) translator to JS (Javascript) there:
Then ASC3: autolevels.as
Is Now in JS:
Code

regards all
