Discussion

  • Discussion of the project mission statement.

  • The mission statement should give some bar for how to proceed in the future. Our philosophy: “Keep it simple.” However, the library as it is is not simple.

  • Are we the keepers of best practices?

  • Keep format modern and relevant. An example issue: Should we support integer data?

  • “Provide a specification and reference implementation of the motion picture industry's preferred image file format for high dynamic range linear scene-referred image data.”

  • Should focus on “Content Creation”

  • Openexr-images repo, reference images. Used by OIIO as test images.

  • Rather than storing a bunch of 4k images, better to provide a program that generates the images on the fly.

  • Start with a reasonable image, then add noise to it, see how compression works.

  • Foundry just advertised increases in OpenEXR speed, they obviously take performance seriously.

  • Nick: whenever I export an image from photoshop, I wonder if the gamut has changed, etc.

  • How quantify is the image of the expect quality?

  • What is the quality of my image? Tests.

  • Should the library include utilities/operators/techniques that check the quality of an image?

  • We are now in a different eco system now from when OpenEXR was first written. We can refer to the existence of tools and techniques that didn’t exist.

  • Before submitting for project adoption, we need to address outstanding SonarCloud bugs.
