问题描述
我有这需要一个流,从手机摄像头旋转图像的类。我的问题是,加载从独立存储照片时(即后用户以前保存的图片)被加载到的BitmapSource。
I have a class which requires a Stream to rotate an image from the phone camera. The problem I have is that when loading the picture from isolated storage (ie after the user has saved the picture previously) it is loaded into a BitmapSource.
我想提取的位图源回如果可能的话流?没有人知道它是否使用Silverlight的WP7?
I would like to 'extract' the bitmap source back into a stream if possible? does anyone know if it is using silverlight for WP7?
感谢
推荐答案
试试这个:
WriteableBitmap bmp = new WriteableBitmap((BitmapSource)img);
using (MemoryStream stream = new MemoryStream()) {
bmp.SaveJpeg(stream, bmp.PixelWidth, bmp.PixelHeight, 0, 100);
return stream;
}
