先触发了jquery.fileupload-image.js中的resizeImage方法
// Resizes the image given as data.canvas or data.img
// and updates data.canvas or data.img with the resized image.
// Also stores the resized image as preview property.
// Accepts the options maxWidth, maxHeight, minWidth,
// minHeight, canvas and crop:
resizeImage: function (data, options) {
if (options.disabled || !(data.canvas || data.img)) {
return data;
}
options = $.extend({canvas: true}, options);
var that = this,
dfd = $.Deferred(),
img = (options.canvas && data.canvas) || data.img,
resolve = function (newImg) {
if (newImg && (newImg.width !== img.width ||
newImg.height !== img.height ||
options.forceResize)) {
data[newImg.getContext ? 'canvas' : 'img'] = newImg;
}
data.preview = newImg;
dfd.resolveWith(that, [data]);
},
thumbnail;
if (data.exif) {
if (options.orientation === true) {
options.orientation = data.exif.get('Orientation');
}
if (options.thumbnail) {
thumbnail = data.exif.get('Thumbnail');
if (thumbnail) {
loadImage(thumbnail, resolve, options);
return dfd.promise();
}
}
// Prevent orienting the same image twice:
if (data.orientation) {
delete options.orientation;
} else {
data.orientation = options.orientation;
}
}
if (img) {
resolve(loadImage.scale(img, options));
return dfd.promise();
}
return data;
},
