BitmapImage是WPF类，不是吗?您的问题未标记为WPF.

您可以阅读我的图像处理文章，了解如何使用GDI +.我知道您可以通过使用流在两者之间存储字节来在Bitmap和BitmapImage之间进行转换.我不确定是否可以访问BitmapImage的像素.

BitmapImage is a WPF class, isn''t it ? Your question is not tagged as WPF.

You can read my image processing articles for how to do it with GDI+. I know you can convert between Bitmap and BitmapImage by using a stream to store the bytes between the two. I am not sure it''s possible to access the pixels of a BitmapImage.
