okay so bestie, you ever look at a picture and be like "what even ARE you"?? that's literally what iinfo is for. it prints information about images. that's it. that's the whole vibe. ✨

it lives in the OpenImageIO tool suite (the whole fam is at http://www.openimageio.org if you wanna go say hi 🫶), and the full detailed documentation ships as a pdf with the OpenImageIO distribution. iykyk.
