Parse PNG or APNG (Animated PNG) to ImageData for React Native.
$ npm install react-native-pixel-pngFor RN >= 0.65, run npm install react-native-blob-util.
For RN < 0.65, run npm install react-native-blob-util@0.16.3, and patch manually to fix: with react-native-web product build will export 'URIUtil' (reexported as 'URIUtil') was not found.
var pixelPng= require('react-native-pixel-png');
console.log(pixelPng); //functionreturn images is Array contains one or more ImageData.
var file= 'https://59naga.github.io/fixtures/animated.PNG';
pixelPng.parse(file).then(function(images){
var i= 0;
console.log(images.numPlays); // 0(Infinite)
console.log(images.playTime); // 1600
var nextImage= function(){
var imageData= images[i++];
if(imageData==null) return;
console.log(imageData);
nextImage();
}
nextImage();
});

imagescan be resized and also keep property e.g.delaybyresizeImageDatasof react-native-pixel-util.
