Reference | size()
Syntax
size(w, h)
Description Sets the size of the canvas in points. The first parameter sets the width, the second parameter the height. If this command is used, it should be the first line in a script - it's illogical to set the size of the canvas halfway a script! The supplied values can be multiplied by "inch", "cm" or "mm". The predefined WIDTH and HEIGHT variables can be used to obtain the canvas size.
