I was wondering if it was possible to change the size of a WriteableBitmap in WP7. I have noticed that the default size is 640x480, and my windows phone application is in Portrait mode, so I would like the height of my writeablebitmap (which I am using to overylay a live grayscale camera image) could be increased accordingly (while ofcourse keeping the same aspect ratio). I have not been able to find anything regarding this anywhere?

为什么不使用相关的构造函数创建所需大小的位图呢？
