How to save a selected word image to image file in open XML in PNG format?

Question

Hi Everyone,
I have a very strange problem. I want to extract the image from word using open xml sdk. Here the user selects the image on opened word, and then clicks on any button, so it should extract the same selected image to any predefined location in the PNG format.
I also tried to do the same thing using Word API, there I am copying the selection of image to clipboard and then getting the image and converting it to bitmap and saving it, but the image resolution is coming very bad. Is there any method through which
I can save the image to file either by Open XML sdk or Word API using C#.
Thanks,
Shahab Abbasi

string fileName = @"C:\test.docx";
using (WordprocessingDocument document = WordprocessingDocument.Open(fileName, true))
var e = document.MainDocumentPart.ImageParts.GetEnumerator();
int picNum = 0;
while (e.MoveNext())
picNum++;
ImagePart imagePart = e.Current;
Stream stream = imagePart.GetStream();
long length = stream.Length;
byte[] byteStream = new byte[length];
stream.Read(byteStream, 0, (int)length);
FileStream fstream = new FileStream(@"C:\abc.jpg", FileMode.OpenOrCreate);
fstream.Write(byteStream, 0, (int)length);
fstream.Close();
