Subject: [PATCH] pil_cv2.check_dpi: fix class membership test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

(depending on how the `PIL.Image` was instantiated – file plugin or array interface – the previous `isinstance` could fail, provoking a fall-through to `cv2pil` which does not work)
