I do not want to resample/resize the image, simply change this attribute. Reason being that Quark uses the resolution to render the image (in this case a jpeg) on a layout. So I was looking for a way to set the resolution to 72dpi without re-jpeging the image. Perhaps its my installation but `mogrify filename.jpg -density 72` hasn't worked either identify -verbose Rendering-intent: Undefined Resolution: 300x300 Units: PixelsPerInch Filesize: 84kb And I get the same results with `mogrify filename.jpg -density 72x72` Odd but as it work on *NIX it isn't a major problem.
