You can use getimage() though it will just get a 24 bit RGB image of what's in the axes, so the graphics won't be burned in at the full image resolution. Though maybe that will be good enough for your needs. Then just call imwrite to write the image to disk:

displayedImage = getimage();
imwrite(displayedImage, fullFileName);
