How to use the pyexiv2.utils.make_fraction function in pyexiv2

To help you get started, we’ve selected a few pyexiv2 examples, based on popular ways it is used in public projects.

Secure your code as it's written. Use Snyk Code to scan source code in minutes - no build needed - and fix issues immediately.
