if you can't read my code, try converting it here[^]

if(NewFrameDelegate!=null)
NewFrameDelegate();

class LocalSource {
 public event NewFrameDelegate NewFrame;
 
 // ...

 private void MoveToNewFrame(){
  Bitmap bitmap = SomeMethodToMakeFrameImage();
  NewFrameDelegate newFrame = NewFrame;
  if(newFrame != null) newFrame(bitmap);
 }
}

class ViewingWindow : UserControl { // or whatever
 void SomeMethod() {
  LocalSource source = new LocalSource(this);
  source.NewFrame += bitmap => {
   // whatever
  };
 }
}

interface INewFrameListener {

class LocalSource {
 // ...

 private void MoveToNewFrame(){
  Bitmap bitmap = SomeMethodToMakeFrameImage();
  INewFrameListener newFrameListener = ViewingWindow as INewFrameListener;

var specificControl= ViewingWindow as YourType;
if(specificControl!=null && speciicControl.NewFrameDelegate!=null )
    speciicControl.NewFrameDelegate.
