How can I merge a created rectangle with an image?

I used the rectangle command to place a rectangle over an image I loaded. How to I save what is displayed in the window as a single image?

I realize I could use inserShape but this doesn't allow me to get a rectangle with curved edges.

Use getframe:

S = getframe(gca); 
im = S.cdata;

I believe you can use

savefig(figHandle, 'NewFigureName.fig')

if you want the image, or use the File>Save As route in the figure window if you want a different filetype. Here's the documentation for savefig .

Hope that helps!
