We're currently using pipelines to support processing large images. Also, in the end we'd like to implement AVIF output support, are there any plans to implement this in the near term future for aurigma?

We're currently using pipelines to support processing large images. Yes, That will load the entire image. There is no way to apply it to pipelines.

Unfortunately, we have no such plans. But I will post the idea for the dev team discussion.
