Playing animated gif files

[cmorgan]

On the desktop I am able to import an animated gif and play it on a different card using this:

put image "airplane.gif" of card "card2" into card image "imageObject"

This doesn't play the animation in the iOS simulator. Is there another way to do this?

put image "airplane.gif" of card "card2" into card image "imageObject"

I'm not sure what the point of that is.

My inclination would be to check iOS documentation as to how it copes with animated GIF images.

Users have requested animated GIF support for years, but Apple waited until iOS 11 (Fall of 2017) to finally implement it.

Unfortunately, because of storage constraints,
the way that I tend to handle animated GIFS
(in a way that gives full programmatic control over animation)
is probably not worth considering.

Hi cmorgan,

welcome to the forum!
Does the GIF on card "card2" play on card "card2"?

Maybe animated GIFs are really not supported by iOS?
I don't know, I don't develop for mobile nor do I own any mobile device like a cellphone etc.

Hint:
... card image xxx
Is only accepted for HC compatibilty, you do not need to write this in LC anymore!
Just use IMAGE or BUTTON or whatever:
...
put img "airplane.gif" of cd "card2" into img "imageObject"
...

Hi All,
Possible but very slow (iOS 11.4)
Maybe display a collection of .png would be faster

Indeed: If you open an animated GIF in GIMP it is easy (but tedious) to export its frames
as individual images.

These stills are extracted from an animated GIF
composed from a sequence of photos by Eadweard Muybridge
that came to 512 KB, as did all the still PNG images:
so NO size overhead, pleasantly enough.
