LINE DEVELOPER DAY 2017 B-7 Our latest app, Creators Studio, lunched in June 2017. With Creators Studio you can easily create, manage and deploy your own Sticker Sets to the Line’s Sticker Store. To create a Sticker you can use your own picture. Just trim out the part you are interested in, add some additional effect and you are done. We tried to make the trimming part as easy as possible. In this talk I will give you an inside view about how this feature works.
