System.Drawing question

[Qwert]

Hello,

I want to draw from one System.Drawing.Bitmap to another. All I can find is
how to draw to a Graphics object.
System.Drawing, System.Drawing.Drawing2D or System.Drawing.Imaging have no
functionality for this.

"The Graphics class provides methods for drawing to the display device."
But I want to draw to an 'off-screen' image.

How does one do this?

Thank you.

Check out Graphics.FromImage. You can create a Graphics object from a
bitmap, draw on it, then save it as a bitmap or display it in a picturebox,
etc.

Thank you both, just what I need.

I was looking wrong, assuming the image or bitmap class would provide the
functionality to copy from one image to another.
