Currently there is not a scripting API or user interface for altering the dimensions of a deck.
Technically you could use deck.encoded, newdeck[], and danger.open[] to serialize a deck to a string, manipulate it, decode it as a deck, and switch the active document to that modified deck, but I don't recommend this.
What are you trying to do which would need to dynamically resize a deck?
y cómo funciona todo eso?
estoy haciendo una versión alterada de wigglypaint agregando muchas funciones extras como mas pinceles y mejor historial de cambios y en eso tambien tenia pensado poder ajustar el tamaño del deck para poder hacer dibujos más grandes pero quisiera que hubiera una forma más rapida y sencilla de hacer sin tener que recurrir a modificar el archivo .deck
And how does all that work?
I'm making an altered version of WigglyPaint, adding many extra features like more brushes and a better change history. I was also planning to be able to adjust the deck size to make larger drawings, but I'd like a faster and easier way to do that without having to modify the .deck file
