I have an animated gif that I want to loop n times (animation.gif). After the loop, I want to show a static image (static.gif). The animation will be displayed over the web, so the file size needs to be a small as possible.
I tried implementing it with Imagemagick by adding the static image with a zero delay ...
convert -loop 3 animated.gif -delay 0 static.gif newanim.gif
Although the static image is shown in the end, the problem is that after every iteration static.gif is shown for a split second.
Another thing I tried was to add the animation 3 times and the static image at the end. This works perfectly but the file becomes too large especially if the animation is long, and if it is looped many times. For instance, a 6.1mb animation becomes ~18mb.
convert -loop 1 animated.gif animated.gif animated.gif static.gif newanim.gif
I'm using Python in a linux environment to implement this, so if there are programmatic ways of doing this instead of Imagemagick that would work as well.
EDIT: I failed to mention a constraint: it needs to work without any client side programming (Javascript, CSS, etc). It needs to be a purely gif solution. This constraint makes it different from How to stop an animated gif from looping
No, you can't. The GIF anim format doesn't provide that ability.
There are various ways to do what you want on a Web page, but you'll need to have a separate file for the static image, and you'll need some code (eg JavaScript, or maybe CSS) to display the static image after the desired number of anim loops.
