如何将WriteableBitmap转换为jpg或其他一些常见格式? [英] How can i convert WriteableBitmap to jpg or some other common format?

问题描述

我有一个应用程序，允许用户执行各种操作，例如旋转和缩放图像，最后，当用户单击保存"时，图像应保存在服务器上.一切正常，但问题是，因为我在使用WriteableBitmapEx将其转换为字节数组后直接保存了WriteableBitmap，保存的图像也是WriteableBitmap，所以我无法使用普通的Picture Viewer对其进行查看.

I have one application that allows user to do various things like rotating and scaling an image and finally when the user clicks on save, the image should get saved on the server. Everything works out fine but the problem is since I am directly saving the WriteableBitmap after converting it to bytearray using WriteableBitmapEx, the saved image is also WriteableBitmap and so I am not able to view it using common Picture Viewer.

我希望将图像另存为JPEG.我该怎么办?
