Windows Phone-裁剪BitmapImage [英] Windows Phone - Crop BitmapImage

问题描述

我有BitmapImage，我需要将其裁剪为大小为200x200的矩形。矩形应包含源BitmapImage的中心。我建立的唯一解决方案CroppedBitmap无法在Windows Phone上使用。

I have BitmapImage and I need to crop it to a rectangle of size 200x200. The rectangle should contain the center of the source BitmapImage. The only solution I've founded, CroppedBitmap does not work Windows Phone.

另一种解决方案可能是创建WriteableBitmap并遍历每个像素，但是我没有更简单的方法了？

Another solution could be to create a WriteableBitmap and iterate through each pixel but I is there no easier way?
