Better compression can also mean a new set of filter methods or a new interlacing algorithm. But yeah, any of them would cause an instant incompatibility. As noted in the relevant issue [1], we will need a new media type at the very least.

- snvzz 1y agoI am hopeful whatever better compression doesn't end up multiplying memory requirements, or increase burden on cpu, especially on decompression. Now, PNG datatype for AmigaOS will need upgrading.

- Arnt 1y agoI don't see why? If your video output is plain old RGB (like the Amiga hardware), then an unmodified decoder will handle new files without a problem. You only need a new decoder if your video output can handle more vivid colours than RGB can express.
- Findecanor 1y agoAn image decoded in the wrong colour space for the output will look wrong. It is not using extra bits to express the increased dynamic range: the existing numeric range is stretched and warped.
- Arnt 1y agoYes. But how bad? AIUI the way it's done is more or less the best that can be done with old video hardware, like mine and like the Amiga. It could be horrible in principle, but actually isn't.
- Arnt 1y agoWe would need a new media type. But the actual new features don't need one, because the news don't break compatibility. https://svgees.us/blog/img/revoy-cICP-bt.2020.png https://svgees.us/blog/img/revoy-cICP-bt.2020.png uses the new colour space. If your software and monitor can handle it, you see better colour than I, otherwise, you see what I see.
