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();
img = decoder.NextImage();
}
}See Assets\Scenes\AnimatedTextures.cs for an example
NB: For speed the decoder will reuse the buffer memory 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.
