PNG-spec VS qoi

Pull requests welcome. :D

There are multiple github issues on the subject where we work on future editions of the PNG spec. (3rd Edition coming soon!)

Especially enticing as the PNG file format does allow for additional compression/filter methods and new ones could be added to a PNG 2.0 standard. A small wishlist discussion about that at the W3C's PNG specification Github.

> But its not like any reader ever supports it fully, hell most readers dont support showing the other images in a png file.

Do you mean APNG? In all fairness, that is not even in the specification although there is discussion to add it. https://github.com/w3c/PNG-spec/issues/26

The one that was specified was MNG but it was a different format and practically no one used it since it was not parsable as a PNG.

Her request is politely-phrased and reasonable. I don't think there's a legal or ethical issue, but respecting the wishes of others when it costs nothing is just kindness.

However, the way that some have seized on it, and then interacted with others in their communities is ... neither polite nor reasonable.

e.g. https://github.com/phoboslab/qoi/issues/35

How do you know it's not a problem for the people who work with computer vision? Let's take this for example - sure, the request itself was presented very unprofessionally, but this is still an example of someone in a computer vision-adjacent field stating in no uncertain terms that they have a problem with the image.

Yes. Without a supporting statement, it's ad hominem. But I provided a supporting statement.

This is the issue I'm taking about: https://mobile.twitter.com/richgel999/status/146443578680850...

Where everyone agrees, yes, the image should be removed. They didn't know about its history. Would he please stop being a gigantic asshole about it.

So if that's not blowing things out of proportion, I don't know what is.

I don't know about CUDA, however I've made an AVX2 based encoder a few months ago : https://github.com/phoboslab/qoi/pull/143

I intend to create an AVX2 based decoder but I had absolutely no time to work on side projects in the past three months.

You might also want to take a look at this streaming encoder if you want to encode large files with a tiny memory footprint : https://github.com/MKCG/php-qoi/blob/main/src/FFI/lib/qoi.c

Not only does compression improve this situation today, but using QOI means improvements may continue to come over time. QOI is a very new, open source image format, and that's already proving to be an advantage. By itself, QOI compression is pretty weak, but YoYoGames have forked it and worked in BZ2 compression to surpass the old PNG format. As QOI itself improves and as YoYoGames continues to work on it, it's almost guaranteed that we'll see the compression ratio in GameMaker get better over time.
