[webkit-efl] APNG support?

[ryuan Choi]

Hi,

IMHO, it looks not critical issue to support apng on the Efl port, because
ewebkit is not widely used and I didn't have any requirement(apng is also
not widely used.) about it but your patch is small enough about
consideration of maintaining cost.

In your screenshot,
you looks using e.

so, I think that we have one user about apng requirement.

BTW,
I am not sure whether chrome will support apng without using extension.
Do you know whether mozila support webp, now?

Best regards,

Well, it's not a format by itself, just a simple extension over PNG, which
is allowed by PNG specs. It follows the rules in that sense. First frame is
regular PNG, so creating thumbnails works fine already, with existing
software.

Chromuim doesn't support it yet, but I sent them a similar patch too. It's
one of the top requested features by Chromuim users.

It's supported by Firefox since 2008.
Safari will support it too, as soon as Yosemite and iOS8 are out, so it's a
good time to get it into WebKit as well.

There are plenty of APNG files already on the internet, deviantart.com
alone reports 600+ results.

It's very simple, and most of the decoding work is done by libpng anyway.
My patch is pretty small, it only extends the functionality of existing PNG
decoder a little bit.

PNG compression vs GIF is another benefit:

Smaller files for the same content means faster web for everybody.
