Loading ...Create your own animated PNGs
GIF Movie Gear has become the first editor to support the new animated PNG (APNG) format. As announced recently, APNG makes the open PNG format a complete superset of previously patent protected but widely used GIF format now that it supports animation while offering better color resolution and transparency.
The format gained native support in Firefox 3 Alpha3, released last week. However since the format is evolving rapidly, the sample APNGs available which follow the most recent specification were not displayed but in the most recent nightlies.
GIF Movie Gear, as its name suggests is a tool for web designers to create animated GIF files. Its author however recently released an experimental version that supports APNGs. I am not an image expert but so far it looks pretty well and I was able to create a simple animated PNG featuring Kit. The experimental version is available as a 30 days trial in zip format.
If you are using a current (as of today) Firefox 3 nightly (Minefield) you can see an animated button below. Otherwise you will only see the first frame of the animation.
You can see the same results in good old GIF format.

Am I the only one who notices that the APNG is about 3 times the size of the GIF?
How on earth does that happen? I would have expected APNG to be superior, or at least not significantly worse than GIF in all cases.

Jonas, good point. I didn’t notice that in my trivial test, but in fact the PNG is 16KB while the GIF is just 6KB. Since the APNG and GIF Movie Gear are both in development versions, I guess this will hopefully improve. I don’t see a successful future if the gap remains so wide, even with PNG advantages.

*clicks “Announced Recently”*… Ah, so that’s what happened to MNG. I never quite figured that out, though I kinda suspected as much. I guess this APNG idea is pretty smart then.
As for the larger filesize, I wonder, is the APNG indexed like the GIF file (because obviously a 24-bit PNG is much bigger than an 8-bit one)? Photoshop seems to say it isn’t, but then again it can’t detect its layers either.

Yep.. I was about to say the same.. and I will… the APNG is 15kB’s long… too bad against a 5kB gif… But.. anyways!
I always loved the possibility of having MNG used by the masses.. but.. that didn’t go very well. So.. here we are, my little APNGie… T_T ^^

Sure APNG is larger than GIF in this case but is the graphic vector or raster based?
I’d be surprised if a vector PNG was that much larger than GIF. This has always been the trade off between the two which is why GIF is still a valid option for some graphics.
Don’t forget the advantages of PNG (24-bit) though,..do we REALLY want all those jaggies? Think how much fun there is to be had with APNG and Jscript.
