Save WriteableBitmap to file using WPF

c#, wpf, writeablebitmap

Solution

Use your WriteableBitmap's clone and use this function as below:

CreateThumbnail(filename, _frontBitmap.Clone());

...

void CreateThumbnail(string filename, BitmapSource image5)
{
    if (filename != string.Empty)
    {
         using (FileStream stream5 = new FileStream(filename, FileMode.Create))
         {
             PngBitmapEncoder encoder5 = new PngBitmapEncoder();
             encoder5.Frames.Add(BitmapFrame.Create(image5));
             encoder5.Save(stream5);
         }
    }
 }

Problem

I have: ``` WriteableBitmap bmp; ``` I basicly want to save it into a file on the disk like the following: ``` C:\bmp.png ``` I read some forums which mentions to read: ``` bmp.Pixels ``` and save those pixels into a `Bitmap` then use `Bitmap.SaveImage()` function. However, I can't access any `Pixels`. Apperantly my `WriteableBitmap` does not have any property named `Pixels`. I use .NET Framework 4.0.
