Frame and canvas together
As with all Sirv options, Frame and Canvas values may be combined. When doing so, the frame will appear on the outside of the canvas. In other words, the canvas area is considered to be part of the image before a frame is applied.

Below is another example, combining a canvas, frame and a title:
