有时要实现BitmapImage与byte[]相互转换,这里实现两个静态方法,直接调用即可。 byte[]转换为BitmapImage: publicstaticBitmapImage ByteArrayToBitmapImage(byte[] byteArray) { BitmapImage bmp=null; try { bmp=newBitmapImage(); bmp.BeginInit(); bmp.StreamSource=newMemoryStream(byteArray); bmp.EndInit...

DisplayImage.Source = wBitmap; } 接下来,我们只要操作WriteableBitmap即可。要使用GDI+,我们需要先把WriteableBitmap的后台缓存交给Bitmap管理,然后使用Bitmap的Graphics进行绘制。 wBitmap.Lock(); Bitmap backBitmap = new Bitmap(width, height, wBitmap.BackBufferStride, System.Drawing.Imaging.PixelFormat....
When your byte array contains a bitmap's raw pixel data, you may create aBitmapSource(which is the base class ofBitmapImage) by the static methodBitmapSource.Create. However, you need to specify a few parameters of the bitmap. You must know in advance the width and height and also ...
