Проблема с heic форматом

var reader = new HEIFReader('test/1.heic'); 
var decoder = new HevcDecoder(); 
var imgData = new ImageProvider(reader, decoder);

  } else {

      var masterItemIds = []; 
      var imageFeaturesMap = fileInfo.rootLevelMetaBoxProperties.imageFeaturesMap; 
 
      for (i in imageFeaturesMap) {

          masterItemIds.push(parseInt(i)); 
        } 
      }
