I’m currently writing an app with Art gallery, and I’m trying to combine cloudDB and KIO4 Base64 together.

This is a mindmap for the testing code

This is how it works:

But the question is: How to call the data and get the wanted picture? Because I don’t know where would the canvas be collected into, thus I don’t know which path should I choose

The canvastobase64 block does not work in my case ( always throws an error: “com.google.appinventor.components.runtime.Canvas$CanvasView.buildCache []” ).

So saved canvas to file and used filetostringdirect for conversion to base64.

Or you can simply use this canvastobase64 extension
