Alternatives that support animated gifs? #755

Closed torrobinson closed 3 years ago

torrobinson commented 3 years ago

Since Croppie doesn't support animated gifs, can anyone suggest an alternative to Croppie that supports gif?

Allowing animated gifs as an avatar/profile picture is more and more common these days, and I need something like Croppie that supports selecting and cropping an animated image.

Does anyone know if any alternatives?

After an extensive search I found that nothing really supports clientside gif cropping.

What I did was, rather than actually perform the crop clientside, I sent up the crop points from:

let cropPoints = croppieInstance.croppie('get');

to the server, and then, serverside, I used ImageMagick to iterate through each frame of the MagickImageCollection and manually cropped each frame before saving.

Same effect, just a little more work serverside.

Edit: Do NOT try to use Magick.Net, it was a total nightmare that introduced artifacts and glitches into every gif. Use ImageSharp instead. It worked flawlessly.
