A unity library to parse a GIF file and extracts the images, just for fun

Copy Assets\mgGif\mgGif.cs to your project.

Alternatively, the upm branch can be pulled directly into the Packages directory, e.g.

git clone -b upm git@github.com:gwaredd/mgGif.git

Pass a byte[] of the GIF file and loop through results.

byte[] data = File.ReadAllBytes( "some.gif" );

using( var decoder = new MG.GIF.Decoder( data ) )
{
    var img = decoder.NextImage();

    while( img != null )
    {
        Texture2D tex = img.CreateTexture();
        int delay = img.Delay;
        
        img = decoder.NextImage();
    }
}

See AnimatedTextures.cs for an example

NB: For speed the decoder will reuse buffers between each NextImage() call. If you need to keep the raw image data then ensure you Clone() it first.

For an additional performance improvement, uncomment mgGIF_UNSAFE at the top of the file and allow unsafe code compilation in the assembly.
