(Keywords: css-moz, Whiteboard: [Hixie-PF] WONTFIX ? -- extension RFE (py8ieh:WG)) 

Just for the record, I would like a style, such as:

-moz-image-frame: auto|<n>;

to select an individual frame from an animated image.
Why?

To make it invisible? Or twice bigger?  :-)  This could have some interesting 
visual effects but... WONTFIX.

Oops - forgot to answer that before.

The request was to manually animate a gif.

Making it invisible is covered by list-style-image: none;
IIRC Changing its size is covered by setting width and/or height.
My mistake: I thought you wanted a selector to match a particular frame of an 
animated gif, and change the style only on that frame while the gif is animating. 
In fact, if I'm correct this time, you would like a property to freeze the 
display on a particular frame.

I can see some use for it, although this possibility may be abused (like using it 
to package several unrelated static gifs into one "animated" gif where the frames 
would be selected one by one).

Maybe it makes sense.  Reopening and moving over to ImageLib to ask for their 
opinion.

ian?
I don't think this is an imagelib issue.  There are APIs on images to start and
stop their animations.  If the style system wants to support this, then let me
know and I can help with some of the nsImageFrame changes to look for new style
properties.

Pav, what we would need is an API to stop the animation at a particular frame.  
Does it exist?

Anyhow I keep this bug as Future/enhancement in case there is another request, or 
if someone wants to implement it (Neil maybe?).

The feature didn't raise a lot of enthusiasm. Close as WontFix.

Neil: if you like, you can make the suggestion on www-style@w3.org (see

Well, -moz-image-region sort of does what I want after I redesign my images.
