如何调整从 nativescript-imagepicker 插件中选取的图像的大小

how can I resize images picked from nativescript-imagepicker plugin

我已经在我的 Nativescript -Angular 代码中实现了 nativescript 图像选择器插件,但我想弄清楚如何调整从 nativescript-imagepicker 中选取的图像的大小,这些图像可以显示为圆形的帐户或个人资料图片

selected 图像将是 ImageAsset, you may set the options with desired width and height then call use fromAsset method on ImageSource 调整大小图像的实例。

context
    .authorize()
    .then(function() {
        return context.present();
    })
    .then(function(selection) {
        selection.forEach(function(selected) {
            // Set values for width, height, keepAspectRatio (boolean)
            selected.options = {width, height, keepAspectRatio };
            imageSourceModule.fromAsset(selected)
               .then((imageSource) => {
                   // imageSource is resized one
               }); 
        });
    }).catch(function (e) {
        // process error
    });
