How to save very large image to original resolution

I have a very large image saved via .tif file (70,499 x 8400). I am trying to plot and fill polygons on this image that are the result from an artifical intelligence neural network (points are in .JSON format). I have no problem plotting the images on the large image, my trouble comes from trying to save the figure to the original resolution. I have tried using export_fig('filename', '-native') but errors keep popping up saying that the image is too large, I have tried using 'imwrite' as well as 'print' with no success. Is there anyway to to achieve this?

Since you'd mentioned imwrite(), I was assuming that you had already been able to apply those to the image itself.
I don't know what exactly you're doing with plot tools, but if you're using ROI tools, you can use createMask() and basic image operations to alter the underlying image. If that's something that you need to figure out how to do, I suggest coming up with a reduced-size conceptual example of the things you're trying to embed and we can see what the options are.

Try to use export_fig's sister image-export utility, ScreenCapture: https://www.mathworks.com/matlabcentral/fileexchange/24323-screencapture
