-34 is -ERANGE which generally gets raised if you request scaling that
your hardware (or driver) can't support. Not all platforms are capable
of performing scaling and those that do support it generally have
limits.
You can also get an -ERANGE return if your coordinates could cause an
integer overflow (e.g., coordinates with values near INT_MAX).
