I wanted to use it as a design platform for a t-shirt costumizing store. But i would like to connect the different modules that i can add to the canvas to my db. Limit the amount of things you could add to the canvas and also limit the size of the different things on the canvas. In that way I could sell a, let say “small print” 10x10 cm, and the user would then be limited to the space defined.

Hi @balle.emil – thanks for clarifying your request!

1. Every time a user has added something or modified the canvas, an event fires (called Canvas Modified) – not sure how your use case works exactly, but you may be able to use this event to track the number of times a user added something and change the canvas to the mode where users cannot select elements on the canvas.
2. For the background image, would a new field in the workflow action called “Not selectable?” when set to YES would disable the ability to select/resize the image work?
3. Regarding the png issue, I’m not able to help without a link to your app or editor. Could you share that with me?

Best,
Alex
