I am plotting an outline on a logical matrix array and need to resave as the same filetype w/ same dimensions including outline.
Any Advice?

are you looking for imwrite()? or some combination of getframe(), frame2im(), and imwrite()?

oh, if the issue is "original dimensions", I guess you need to make sure (if not using CVT) that the image is being "displayed" on your "axes" at 1:1 pixel resolution of the original image. You can set that up by ensuring your figure is at least as large as your image and axes is exactly the same size, by setting the figure's "Units" property to "pixels" and settin the "Position" property appropriately. In the past I've had to adjust the pixel size by +/- 1 pixels to get frame2im to output the right size.
