10.7.2 Pan/Zoom Window Detector Coordinates

Detector coordinates define locations on the camera detector. Detector coordinates are always

positive integers. For a particular camera type, detector coordinates never change. The detector

coordinate origin is always the upper left corner of the detector. This origin does not start at x=0,

y=0, rather it relates to electronic timing of the camera. X values increase to the right and decrease

to the left. Y values increase going down and decrease going up.

The Pan/Zoom window represents the boundary of active pixels on the detector. Use the PNW?

command to retrieve the upper left and lower right corners describing the camera detector pan

window limits.

The following example describes how to retrieve the boundaries of the camera detector and set the

upper left corner of the capture window to the upper left corner of the detector.
