JPEG 1 (the original one) specification is also paywalled. But writing encoder and decoder, and producing/consuming JPEG images are still totally free, it's only the official specification document that's not...

Great work, and thanks for sharing! I tested it briefly, and it worked quite well on reasonably sized images. A few thoughts: - I found it impressive that the binary...

> I've actually not tested animations, but I believe `jxl-oxide-cli` produces identical APNGs? I haven't really touched that part of the code. Ah, I remember `png` produces broken APNG when...

Currently jxl-oxide allocates buffer for the whole image when decoding to image (this means ~5GB of memory for a single three-channel 23164x18480 frame). Maybe we need a streaming decode option...

A few thoughts on this issue: - For some images, it might be inevitable that the memory usage is high; we need to keep full framebuffers if they are used...

Optimizing edge-preserving filter is something I've tried before (#80), but it surely seems insufficient. Maybe I'll need a different approach/strategy to apply those filters...

I mean, it needs more optimization including those copies and memory accesses. It should be more cache friendly indeed, I'll consider keeping small scratch buffer.

- 주석을 정의하고 - (#12와 함께) 공백 문자를 정의하고 - 공백 문자와 주석을 무시하도록 하면 대부분의 모호함은 해결할 수 있을 것 같습니다. 근데 좀 복잡해지려나요...?

C의 `scanf`는 `%d`로 정수를 받은 뒤 `%c`로 문자를 받을 때, 정수 뒤에 따라오는 공백을 포함한 문자를 받습니다. `%d`가 그 뒤의 공백까지 처리해 주지는 않는 것입니다. ``` C #include int main()...
