Screen". The Zoom factor is calculated so that all of the image is displayed in the space available in the
viewing area.

Zoom=1
corresponds to a full resolution display: each pixel on the screen corresponds to a pixel on

corresponds to a half resolution display: a pixel on the screen corresponds to the average
of 4 pixels on the Digital Detector.

image projected onto the Digital Detector. This facility is not available when viewing SCPT images.
