Among users and maintainers of the PNG and MNG formats, APNG had a lukewarm reception. In particular, PNG was conceived to be a single-image format.[3] APNG hides the subsequent frames in PNG ancillary chunks in such a way that APNG-unaware applications would ignore them, but there are otherwise no changes to the format to allow software to distinguish between animated and non-animated images. Some of the main concerns arising from this were the inability of applications to negotiate for PNG and APNG, or distinguish between PNG and APNG once received, or for legacy software to even inform users that there are additional frames. Glenn Randers-Pehrson spearheaded efforts to reconcile the PNG purists' position with that of APNG proponents by recommending changes to APNG's format and proposing the use of a unique MIME type (e.g., video/png), but the APNG proponents only added the different MIME type (image/apng)[4] while insisting on the use of the .png extension instead of .apng, leading to the format not being approved by the PNG Development Group.[5]

I'm having trouble getting .apng files to work - they preview correctly in Firefox (meaning when drag'n'dropped into a Firefox window, they animate the way they're supposed to) but when I drag'n'drop the same file into xcode, I see only the first frame. No animation. When previewing in a simulator, no animation - just a static sticker.

pdm, You're suggesting this is something that's supposed to work? I'll be happy to file a bug report. I was assuming I was doing something wrong, or creating the APNG files incorrectly. I couldn't find any examples, or samples, only sporadic posts about how it's supposed to work. The compression achieved using apngasm is outstanding, so it'd be great if we could get it working. KM

FFmpeg can decode and encode animated png, as well as animated gif and webp. (No other FFmpeg output formats support a loop flag in the container, as far as I can tell, not even nut, mkv, or ogg.) Older versions of FFmpeg only supported apng as an output format (encode but not decode).

My animation has a transparent background. The final format has to be either .apng or .gif (for iMessage Stickers submission to Apple). Gif doesn't support transparent backgrounds so it has to be .apng. Can I export to .apng?

So okay, I like Toyhou.se and I'm grateful for what they do however as an animator it bothers me that only gif files are supported on TH, I guess it's fine if you don't bother much with quality but gif is kind of a museum piece for a while and the web browsers on the net supports formats which has better compression and better image quality, for a bit longer animation which has many details not only rendering them in gif butchers the quality and is the triple of the filesize of an apng or a webp but also I can't upload somewhat longer animations in gif cause they take much more space.

Like I said webp and apng is now supported in every major webbrowser, it'd be great if TH would support atleast one of them so those who want to upload animation in better quality or longer animations shouldn't need to worry much, implementing either webp or apng shouldn't be hard , from what I see apngs don't work on the site cause the animation frames are deleted once uploaded to TH (bad compression from TH's side ?) and webp doesn't being recognized/allowed at all.

I'd approve a lot if animated png files would stay animated once uploaded or even if webp files would be supported, not only apngs and webp allows better quality animations, it's also a lot easier to stay in the 4MB filesize limit with them.

I think they decided to use a low quality compression script or addon which removes apng's animation capability ? It's kind of sad cause it seems their display engine would natively support APNGs and WebPs too if they would allow uploading them without degrading it/removing animation frames (from what I assume is a unneeded image compressor ?)

+1Tried to upload an apng file today, and the animation was broken. I'm really sad because I don't wanna upload a GIF version of this file, as it alter the final result...I hope this will get added to the to-do list, soon or later I don't care, I just want to know it'll be here one day.

ADDITIONAL UPDATE: So as a little test I pulled the code from the embed on this page and used a code block to add the identical code and boom it works... so I think it may be the squarespace image uploader/reader that is at fault. So I tried directly calling the uploaded asset using its squarespace ID and a codeblock using similar code and that does not work.... it seems as long as the apng is externally hosted it works. Does this make sense?

So you currently need to link to the image hosted elsewhere using a codeblock... when you do it this way the apng's work flawlessly.

Obviously there are some cons to this as well... so use AYOR

Export module of VirtualDub APNG Mod supports 4 color modes: RGB Color (with or without alpha channel) and Grayscale (with or without alpha channel). Export to indexed/paletted apng is not supported.

Of course i understand fix that isn't an easy work, because it would need a lot test of compatibility on root code and most important, no much people is worried for that, but it's a fact that apng quality is far away from gif.

After a lot tests i achieved reduce considerably the weight of that apng to be viable use it on web, my last wall is the compatibility on Chrome. I insist Chrome have native compatibility with apng, the issue is just when file is upload on vignette.

Convert several png files into an animated png file. This package exports only a single function `apng'. Call the apng function with a vector of file names (which should be png files) to convert them to a single animated png file.

> They can say "thumbnails are forbidden" and sound/text is fine, but it doesn't work that way in the open source world. If people genuinely *need* thumbnails, there will be 3rd-party chunks with thumbnails eventually. This is life. Without enforcement mechanism, it's just a recommendation.

I always understood their stance to be "Follow JPEG's example. Multiple representations of the same frame (ie. embedded thumbnails) are fine." but I see your point.

That's one of the other reasons I try to recode APNG to PNG wherever I can get away with it. I'm doing my part to keep it from reaching that tipping point where it becomes the de facto winner.

(Though I stop short of secretly transcoding APNG to PNG while letting AniGIF through unmolested. I do have principles.)

...and I don't think that battle is lost. a LOT of applications which handle PNG and animated GIF either require the user to seek out a plugin or simply don't support it.

So far, my side has quite a bit of hope on the browser end of things with only Gecko and the latest versions of WebKit supporting it out of the box, leaving IE, Chrome, and Opera without APNG.

=apng

(Even if you count the older WebKit versions which will fade with time, that's still only 22-23% of users who are guaranteed to eventually support APNG animation.)

> Right. But even YouTube just implemented video->gif converter, because nobody can fight the law of supply and demand. Where there is demand, there will be supply.

To be honest, now that I have the extension to FlashBlock-ize GIF animation in Firefox and I've put in the effort to write a reasonably efficient (1000 images in 9 seconds on a 7200RPM drive) pure-Python "is this GIF animated?" module, I've been starting to mellow out regarding GIF animation.

The more they rely on it, the less likely they are to mash their animation in with the Javascript that the stupid site design of the week abuses for things like page layout.

I'm just:

1. ...annoyed because, if APNG gains significant traction, I have to make sure that my efficient solutions also handle that and that's more work for me.

2. ...being a grumpy old 29-year-old fart because "As harmless an exploit as a two-frame gif with a long delay and porn on the second frame is, AniGIF and APNG still violate the 'never trust the user to be too smart or vigilant' principle of computer security."
