What are the use cases for this?

3

to be upfront, the practical use cases are fairly niche, generally situations involving EditableImages where roblox’s apis for images would be insufficient

a good example would be procedural/user-generated image data that needs to persist or be transferred efficiently (a raw uncompressed 1024x1024 RGBA8 image is be over 4MB in size, exceeding the limit for a single datastore key). picguin also opens up the ability to fetch and decode images from hosts outside of roblox itself

use cases aside though, the project primarily exists to provide a consistent and ergonomic interface to deliver the most performant image codecs possible in pure luau. i’m making this because i think something like this absolutely belongs in the ecosystem
