Generally I use PHP, and ImageMagick, but as far as I can tell it seems the ImageMagick group refuse to implement the ability to create/understand animated PNG files?
What tooling can I implement to take a dozen JPEG files and create an animated PNG out of them? I'd prefer to have a PHP api, but I can branch out into another language if required!
Thanks
As of ImageMagick 7.0.10-31, Animated PNG is supported.
magick -delay 100 -loop 0 frame1.png frame2.png APNG:myanimation.png
parameters:
-delay 100
specifies a duration of 100 centiseconds (aka one second) per frame before moving on to the next frame.
-loop 0
tells the animation to repeat forever.
APNG:___.png
specifies the output should be animated png.
(thanks to @fmw42 for improvements)
note: on MacOS Ventura, this seems to require ffmpeg as well.
