Bitmap as Control

[visualizor]

When I instantiate a Bitmap like so:

Bitmap pic = new Bitmap("D:\\Myfolder\\mypic.png");
DynamicLayout dy = new DynamicLayout();
dy.Add(pic, True, True);

It can be added to the layout even though the DynamicLayout.Add method takes a Control as its first arg. How does that work?
If the pic gets passed into another method as an object, where Controls are added to a layout, I only have an if to catch Controls.

if (incoming is Control c){
...
}

This Bitmap will slip through...

It works because of this implicit conversion on Control. It works the same for strings to create a Label. It creates an ImageView to host the bitmap, so your if statement would return an ImageView containing that Bitmap.

But i meant the if didn't work
I think you're familiar with Rhino3d so here's the issue:

How can my method catch everything that can implicitly be converted to a Control in its args?

Unfortunately, since the incoming parameter is an object (not a Bitmap) there's no way for the compiler to know that it should use an implicit conversion. So if you want your 2nd script to handle a Bitmap/string input but translate it to an Eto control, you have to do it explicitly:

if (x is Bitmap b)
  x = new ImageView { Image = b };
if (x is string s)
  x = new Label { Text = s };

A = x is Control;
