Summary of Changes

Hello @MilkClouds, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the to_pil_image method within the MediaRef class to enhance its flexibility. By removing a hardcoded image format specification, the method can now dynamically adapt to different image data formats, improving its versatility for image conversion tasks.

Highlights

• Increased Flexibility: The to_pil_image method has been updated to remove the hardcoded format="rgb" argument when calling to_ndarray. This change allows the method to handle various image formats more flexibly, as determined by the underlying to_ndarray method or through passed keyword arguments.

Code Review

This pull request aims to add flexibility to the to_pil_image method by removing the hardcoded format="rgb". While this is a good goal, the current implementation can lead to silent errors where images are generated with incorrect colors if a BGR-based format is requested. My review includes a suggestion to add a check that prevents this issue by raising an error for incompatible formats, ensuring the method is both flexible and robust.
