Query images

Images are incredibly useful, however there are many ways to store and manipulate them. This example focuses on querying image frames from a catalog server.

The dependencies in this example require rerun-sdk[all].

Setup

Simplified setup to launch the local server for demonstration. In practice you'll connect to your cloud instance.

Compressed image

Compressed images are just stored as a string of bytes, so you can query them directly and transform back into a raw image.

Raw image

Raw images are stored in a flattened layout, so we need to reshape them. These format details are written to the RRD when images are logged.
