You can even do this from Tk, just type:

    dpi_value = root.winfo_fpixels('1i')

(where "root" is your Tk() window) to get the currently used dpi value, or:

    root.tk.call('tk', 'scaling', '-displayof', '.', dpi_value / 72.0)

to adjust the dpi value to your needs (this should be done before creating any
widgets besides the Tk() window though).
