AVIF Support

[danpetitt]

Hi Dirk; thanks again for a great library. Do you have any plans on supporting the new AVIF format?

[dlemstra]

Support for reading was AVIF introduced in this version: https://github.com/dlemstra/Magick.NET/releases/tag/7.20.0.0. And I just updated the release notes to include the note about write support for this version: https://github.com/dlemstra/Magick.NET/releases/tag/7.22.0.0.

Thanks @dlemstra for AVIF support. However, I tested with the samples in https://github.com/link-u/avif-sample-images, there are some files that Magick.NET cannot open:

https://github.com/link-u/avif-sample-images/blob/master/plum-blossom-small.profile0.10bpc.yuv420.alpha-full.avif
https://github.com/link-u/avif-sample-images/blob/master/plum-blossom-small.profile0.10bpc.yuv420.alpha-full.monochrome.avif
https://github.com/link-u/avif-sample-images/blob/master/plum-blossom-small.profile0.10bpc.yuv420.alpha-limited.avif
...

You will need to report this issue to the developers of https://github.com/strukturag/libheif. Magick.NET uses that library to read the AVIF images.

@d2phap have you reported this isse to the developers of https://github.com/strukturag/libheif? I could not find the ticket and I have the same issue.

[d2phap]

@agravity-philipp oh I think I forgot.

[agravity-philipp]

@d2phap I did that for you: https://github.com/strukturag/libheif/issues/697

Hi @dlemstra ! Please note, that this issue was fixed: https://github.com/strukturag/libheif/issues/697#issuecomment-1314288074

[dlemstra]

We will need to wait for a release before we can have this fix in the Magick.NET library

Hi @dlemstra ! This was already released in version v1.14.0 or at least it is in the current version 1.14.2. Is it already included in 12.2.2 ?

[dlemstra]

In the release overview (https://github.com/dlemstra/Magick.NET/releases) I also have a note of the dependencies that are updated. And the file https://github.com/dlemstra/Magick.NET/blob/main/src/Magick.Native/libraries.md contains the most recent versions of the libraries (note: it might be possible that this is not yet released).

But to answer your question the update to 1.14.0 was done in version 12.2.2.

I've just converted PNG with size 235Kb to AVIF with 10Kb using the 13.5.0 library version and the result is very very bad picture quality. I compared the result with the native Linux application ImageMagick (convert) and the result was 21Kb, and the picture quality is far better.
