destinationRect
The destination rectangle in container coordinates.

Horizontal source (image) DPI.

Vertical source (image) DPI.

Horizontal target (screen) DPI.
targetDpiY
Vertical target (screen) DPI.
All visible objects in this container will be drawn into the current context.
This method uses the resolution (DPI) values specified and not the values stored in the container. Use this method when burning the container objects into any context.
To burn a container into the context of the image being automated, use Burn.
This example will create a container, add a couple of objects and then burn it into the viewer
