When i put arg --preprocess none on test . The resolution of output image is same as input but the size on disk of ouput is 18 times bigger than input, why is that
The size on disk does not exactly correlate with the image resolution, because the images can be compressed. Flat monotonic images will take smaller space than detailed complex images.
