I want to draw big-sized pictures, someting about 3000 x 3000 pixels. The problem is that procesccing output window has no zoom in/ zoom out, and I can't see whole canvas on the screen. Is there a possibility to make a zoom by code?
p3 will "helpfully" rescale your output to fit the screen, whether you want it to or not. previous versions didn't do this and you could draw and save images larger than the screen.
i often use svg export and scale up either using a graphics package or when printing.

You can always use scale()
but will "3000x3000" stay "3000x3000", or it become "1000x1000" after scale?
