(please change severity to wishlist) I emailed the apng creators shortly after it appeared to notify them of an apparent bug in either KHTML or apng in that KHTML was displaying the last rather than the first image in the sequence. At any rate the authors expressed an interest in working to get apng working in KHTML since Safari too would benefit. I believe we use Qts PNG-rendered so we probably need to fix the last-image bug there. The APNG specification has been worked out and the implementation completed. It's been included in the Mozilla tree as a patch to libpng for a few months now. The new spec is here: http://wiki.mozilla.org/APNG_Specification I'm not sure KDE uses libpng at all.. but if you do, the libpng patch is available here: http://littlesvr.ca/apng/ Unfortunatly Firefox has beaten Konqueror to this. *gives it a nudge* Looks like Opera has it too. But wasn‘t APNG sanctioned by the PNG inventors in favor of MNG (which is superior in my eyes), but still would love to see that. Finally using alpha-transparent throbbers (that spinning wheel to indicate progress going on) that look good on ANY background :) Not only did they reject APNG but they actually created the MNG format - only to reject themselves at a later point - stating somewhere that they felt PNG should be a stationary format only. Now 1 problem there is whit APNG is if you create an animation in a program like VirtualDub APNG Mod 1.9.11.1 - it is stated that it's not cross-browser compatible - so I guess Linux users may not see it correctly.... I guess! I think the best chance of getting an update animation format compared to gif - is if google succeeds in turning WebP into an animated format too, it is said on there page that they are currently working on that a.m.o. Nevertheless, I have voted for this subject too-> anything that can replace the insufficient - but not necessarily redundant gif format - has my vote!! :-) FYI, the code for native APNG support in WebKit: https://bugs.webkit.org/show_bug.cgi?id=17022 APNG is already supported in all major browsers (except for Edge/IE, naturally). I would vote having Plasma supporting it (not just khtml), since it would allow, for example, users to set simple animated wallpapers (i know... system resources... but it's not for the faint of heart, anyway ;) Could you check if adding a Qt plugin for APNG allows Konqueror to display APNG animations? https://github.com/Skycoder42/qapng Dear user, KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6. Please migrate to use a QWebEngine based HTML component. We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes. For security issues, please see: https://kde.org/info/security/ Sorry that we did not fix this issue during the life-time of KHTML. Greetings Christoph Cullmann |
