Hello,

The Processing examples (in the File menu) for SharedCanvasClient and SharedCanvasServer work:

Start the server first and then the client.

Start with simple modifications to the examples and build on that.

There are resources here:

I have tried but I’m a begginer and i don’t know which functions use.
For example i don’t need a continued communication but first of all i want write a canvas after click on a button and finally send all to server.
