如何在Windows Phone 7上将BitmapImage的大小调整为50x50？

Question

I need to resize a BitmapImage to 50x50 before uploading it to my server. How do I do this on Windows Phone 7 with Silverlight C# .NET on the latest SDK 7.5?

Answer 1

Try this

WriteableBitmap wBitmap = new WriteableBitmap(yourBitmapImage);

MemoryStream ms = new MemoryStream();

wBitmap.SaveJpeg(ms, 50, 50, 0, 100);

The stream will contain your resized image
