The current mobile phone cameras produce JPEG images with very high resolutions. The “DPI” in the JPEG file are set to 72 x 72dpi for display on the screen. This results in a calculated page format of over one meter due to the high resolution of the cameras. If such a JPEG file is converted to PDF then the 72dpi and the 3000-4000 pixels result in a PDF page size of e.g. 140 x 100cm. If such images are e.g. sent as attachments by email and the MSG/EML email file is converted to a PDF, one gets a PDF file containing e.g. all pages A4 format, but the JPEG attachment has a much larger page format.
To prevent this and get an approximately uniform page format when converting JPEG photos, there is now a new option to automatically adjust the “DPI” during conversion. An adjustable tolerance (from 10 to a maximum of 20%) is also taken into account, whereby the automatic adjustment only takes place if the DPI setting in the JPEG exceeds the page format “A4 + tolerance”.
