How Do I Efficiently Convert a System.Drawing.Bitmap to a WPF BitmapImage?

System.drawing.bitmap to the efficient conversion of WPF Bitmapimage

WPF applications usually use

class processing images. However, when dealing with the existing

object, converting it into System.Windows.Media.Imaging.BitmapImage is a very useful step. This conversion allows these images to display and operate in WPF applications. System.Drawing.Bitmap BitmapImage The most effective way to convert to

The most effective way is to use

. The following is a detailed step: System.Drawing.Bitmap BitmapImage MemoryStream Create a object, and use the

method to save the bitmap in the memory flow in the memory flow in the memory flow.

using(MemoryStream memory = new MemoryStream())
{
    bitmap.Save(memory, ImageFormat.Png);
    memory.Position = 0;
    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.BeginInit();
    bitmapImage.StreamSource = memory;
    bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
    bitmapImage.EndInit();
}

The
1. settings of the memory flow back (0) can be read from it. MemoryStream System.Drawing.Bitmap Create a object. Save() ImageFormat.Png Use and
methods to initialize and complete
2. . Position Set the
attribute of as the memory flow in order to load the image from the flow.
3. BitmapImage set
to cache images to speed up the follow -up access speed.
4. BeginInit() Use to end the initialization of EndInit(). BitmapImage
5. After completing this conversion, BitmapImage Objects can be used like any other WPF image resource, such as displaying it or executing the image operation in the StreamSource control.
