Thinking back to the old days, are you sure the black and white image you have in mind didn't come from the "lowsrc" attribute of an img tag? Progressive jpeg is typically full colour from the start, and it does offer the progressive enhancement of resolution that you mention.
Interesting, just last week I had a use for lowsrc for the first time in years and tried to use it, only to find out it had been removed from all browsers a while back.

>so many companies lawyers will prevent engineers even looking at it to write a clean-room implementation. Maybe you should look up what 'clean-room' reverse engineering is. One person looks at the code, writes down how what it does, then gives that description to another person who writes CLEAN-ROOM code based upon the description. There's no difference in doing a clean-room implementation of GPLv3 code than of any…
The difference is that the lawyers for some companies will not sign off on employees even looking at GPLv3 sources. Rightly or wrongly, this really does make a clean-room implementation impossible. One can reasonably argue that this is stupid and not the fault of the GPL. However, it's also reality, and a real block to adoption of technologies like image formats.
Get better lawyers.
Clean-room implementation has been around for ages, I've done it professionally myself, both from source code and disassembly.
Also not every company has clueless lawyers, nor does a clean-room re-implementation of this format need to come from a company, I'd say it's more likely not.
Seriously this sounds more like GPLv3 scaremongering than anything else, I've never seen anything like this in my professional life as a developer.
edit: as for my personal preference, I think GPL is a great license for full application/solution style software, but for libraries/frameworks, I prefer permissive licensing.

> Wow, starting with an unusable license If you want to use it commercially without publishing source, just buy a licence from the author. Buying licences isn't exactly uncommon. Or are OS X/iOS/Windows also unusable for you?
The author claims it to be royalty free. Also commercial "standards" by one party are worthless
> The author claims it to be royalty free.
And the author delivered: With GPL3 source.
> Also commercial "standards" by one party are worthless
Very true, but I can't see how that applies to this project? First, the existence of this repository doesn't preclude proper standardization. Second, the reference implementation is freely licensed, not commercial.

#214This is really interesting. One of the most interesting parts is the progressive decoding/responsive images. http://flif.info/example.php (go to the bottom of the page). Basically, the last example shows that, if you want a scaled version of the image, you can simply stop decompressing. No need for multiple image files. Just create one with very high quality and decompress until you get the quality you want and scale…
Who needs mipmaps?
Re: Free Lossless Image Format
#215I imagine images appearing as fast as I can scroll, with enough visual clue to them to find images way way more quickly than with thumbnails today. As a start, thumbnails could use post" rel="nofollow">http://www.hookad.com">post

#216One more nice feature they didn't mention: unambiguous pronunciation.
So, is it eff-leef or fleef ?

#217Why all the hate for GPLv3?
Sharing code is no longer cool if people have to share back. Or at least so it seems. The GPL-hate in here really is quite immense, even though time and time again, RMS has been shown to be right about his stance on freedom. Should we attribute it to people's desire for a quick ("free") fix over long term considerations? It's hard to tell, but I suspect the silicon valley influence here doesn't help. There everyone w…
RMS himself was against putting such formats/codecs in GPL. Suggested Apache 2 license. See comments above for details. QED.

#218Earlier quoted context omitted.
It's not about being apologetic or anti-freedom, it's all about the reality of software. If it gets reimplemented with a more libral license, then the more liberal version will dominate. If there is any incompatibility whatsoever, the more liberally licensed version will win. Look at gcc for an example: it has gcc-specific extensions and there are other compilers with more open license. These compilers are gaining th…
GCC has been around for 30 years. Only in the past 5 years has LLVM been around, and LLVM really is the only compiler to ever have matched GCC. The value GCC has provided to the software community in large is immense. Do you think it would have survived this far if it had been MIT-licensed all along? To support this argument, I'd like you to think about all the other compilers that never had a 10th of the traction of…
GCC also almost died in the 90s.
Re: Free Lossless Image Format
#219Can the progressive data obscure previous portions of the image?
If so, it can also be a hacky video format.
EG: A flif would specify how many megabytes it used per second. There would not be discrete "frames".
If a video flif said that it used 1MB per Second, and you wanted to see what the video looked like at 10.8 seconds, you would download 10.8MB .

The GPU!- skipping those pixels hurts the cache, even if swizzled :)
