Once the recognizable text has been filtered from the facsimile transmission, the remaining images are edge-fit and output to the transmittal data file by position and other rendering information.  The transmittal file is sent to the device with the viewscreen.  The device then uses the information contained within the transmittal file to render a version of the facsimile transmission image and display it on the viewscreen.
