Somebody can please tell me how to enlarge pixel art using Pixen? I've drawn something but i don't know the procedure to enlarge the image so that it can be seen in a normal size.
From the logic of a question you need "Scale Canvas" function.
As we can see on the screenshot there is addressing to this function on the developer page, however, the link directs to nothing related to the scaling. So, probably, this function was disabled or changed, but it should be there eventually.
