I want to achieve the following property of Canvas Fit Width and Fit Height in Code.
I have a set of conditions and based on that I have to set it in cocos creator. Any help in right direction would be appreciated.

I don’t know what you really want, but there are properties:

Canvas.fitHeight
Canvas.fitWidth

I hope it can be of any help to you.
