Better Portable Graphics (BPG) support please.

• High compression ratio. Files are much smaller than JPEG for similar quality.
• Based on a subset of the HEVC open video compression standard.
• Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0, 4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCgCo and CMYK color spaces are also supported.
• Native support of 8 to 14 bits per channel for a higher dynamic range.
• Lossless compression is supported.
• Various metadata (such as EXIF, ICC profile, XMP) can be included.
• Animation support.

Sounds like it's basically just HEIC / HEIF / HEVC. You can use that already in Paint.NET.

 

But, I would just use AV1 / AVIF. It's newer and not encumbered by patents. There's no way I could include BPG support in the main app because of the patents (HEVC), and therefore the per-user royalties that it would cost. Similarly, I can't include HEIC write support out-of-box -- you either have to buy the codec on the Microsoft Store, or install @null54's Heic FileType Plus plugin.

According to the Wikipedia article it appears to be an alternative HEVC container format that only supports a subset of the possible HEIC/HEIF/HEVC features.

Agreed and understood. I wasn't aware of all hoops you would need to jump through to incorporate BPG, whereas AVIF is a great alternative actually. Thanks for responding so promptly.
