Probably means there will be new PNGs that old software won't be able to open.
It makes sense, right? Is there a way around that when adding new features to a file format?
The alternative is to make another file format for clarity, but it's not really what you want to do.
That depends. Something like HDR should be able to fall back to non-HDR since it largely just adds data, so if the format specifies that extra information is ignored, there's a chance it works fine.
I see, but the animation feature cant be compatiable no?
Likely, you'll see the first frame only on older software. Encoding animation in a dedicated animation chunk and using the base spec for the first keyframe sounds like the sane thing to do, so they likely did that.
I'm not going to look into it now, because I would then have to implement it. :D
Haha dont worry, just curious. Your answer is good!
