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?
