You can create an animated GIF using the Image I/O framework (which is part of the iOS SDK). You will also want to include the MobileCoreServices framework, which defines the GIF type constant. You need to add these frameworks to your target, and import their headers in the file where you want to create the … Read more
convert input.gif -coalesce -repage 0x0 -crop WxH+X+Y +repage output.gif Animated gifs are often optimised to save space, but imagemagick doesn’t seem to consider this when applying the crop command and treats each frame individually. -coalesce rebuilds the full frames. Other commands will take into consideration the offset information supplied in the original gif, so you … Read more
You can use the libgif library. It allows you to start/stop the gif and control which frame the gif is on. <script type=”text/javascript” src=”https://stackoverflow.com/questions/2385203/./libgif.js”></script> <img src=”./example1_preview.gif” rel:animated_src=”./example1.gif” width=”360″ height=”360″ rel:auto_play=”1″ rel:rubbable=”1″ /> <script type=”text/javascript”> $$(‘img’).each(function (img_tag) { if (/.*\.gif/.test(img_tag.src)) { var rub = new SuperGif({ gif: img_tag } ); rub.load(function(){ console.log(‘oh hey, now the gif … Read more
Inspired by the answer of @Karussell I wrote Gifffer. Check it out here https://github.com/krasimir/gifffer It automatically adds stop/play control on top of your Gif.
The accepted solution did not work for me. After some more research I came across this workaround, and it actually does work. Here is the gist of it: function showProgress() { var pb = document.getElementById(“progressBar”); pb.innerHTML = ‘<img src=”https://stackoverflow.com/questions/780560/./progress-bar.gif” width=”200″ height =”40″/>’; pb.style.display = ”; } and in your html: <input type=”submit” value=”Submit” onclick=”showProgress()” /> … Read more
It’s not too hard. Drop a picturebox onto your form. Add the .gif file as the image in the picturebox Show the picturebox when you are loading. Things to take into consideration: Disabling the picturebox will prevent the gif from being animated. Another way of doing it: Another way that I have found that works … Read more
I haven’t tested it but apparently you can add quicktime animations to a pdf (no idea why). So the solution would be to export the animated gif to quicktime and add it to the pdf. Here the solution that apparently works: Open the GIF in Quicktime and save as MOV (Apparently it works with other … Read more
I couldn’t get the most popular answer to this question (above by Dario) to work properly. The result was weird, choppy animation with weird artifacts. Best solution I have found so far: https://github.com/XamlAnimatedGif/WpfAnimatedGif You can install it with NuGet PM> Install-Package WpfAnimatedGif and to use it, at a new namespace to the Window where you … Read more

Instead, please use imageio, which was developed to solve this problem and more, and is intended to stay. Quick and dirty solution: import imageio images = [] for filename … Read more
