我试图将heic转换为jpg。我在js上使用official library。问题是我可以从存储库中解码一张heic照片（回调函数返回一组数据），但是我无法解码在iPhone上拍摄的heic照片（在这种情况下，回调函数根本没有返回任何东西）。不能将iPhone heic照片转换为jpg
有没有人试图将iPhone上制作的heic照片转换为jpg格式？
var reader = new HEIFReader('test/1.heic');
var decoder = new HevcDecoder();
var imgData = new ImageProvider(reader, decoder);
reader.requestFileInfo(function(payload) {
if (payload.success !== true) {
console.error("Could not read file:", url);
} else {
var fileInfo = payload;
console.log("FileInfo contents:", fileInfo);
if (fileInfo.rootLevelMetaBoxProperties) {
var masterContextId = fileInfo.rootLevelMetaBoxProperties.contextId;
var masterItemIds = [];
var imageFeaturesMap = fileInfo.rootLevelMetaBoxProperties.imageFeaturesMap;
for (i in imageFeaturesMap) {
if (imageFeaturesMap.hasOwnProperty(i) && imageFeaturesMap[i].isMasterImage === true) {
masterItemIds.push(parseInt(i));
}
}
console.log("Master images in the file:", masterItemIds);
imgData.requestImageData(masterContextId, masterItemIds, function(data) {
console.log(data);
});
}
}
});
