loadImage(imgUrl,img => {
document.body.appendChild(img);
},
{
maxWidth: 750,
orientation: true,
canvas: true
})the code above will throw a network error on iOS 9
XMLHttpRequest Exception 101: A network error occurred in synchronous requests
my temporary solution is replacing loadImage.fetchBlob with the function below
loadImage.fetchBlob = function (url, callback, options) {
function executor(resolve, reject) {
var img = new Image();
img.src = url;
img.onload = function () {
var c = document.createElement('canvas');
c.width = img.width;
c.height = img.height;
var ctx = c.getContext('2d');
ctx.drawImage(img, 0, 0);
c.toBlob(bin => {
resolve(bin);
});
};
img.onerror = function() {
reject(Error('load image fail'))
}
}
if (global.Promise && typeof callback !== 'function') {
options = callback; // eslint-disable-line no-param-reassign
return new Promise(executor);
}
return executor(callback, callback);
};
