3.8.2
Vertical Window
3.8.2.1 Set Vertical Window (
‘svw’
)
The
‘svw’
command sets the vertical area of interest. The camera will
deliver to the Camera Link interface, per frame, only the range of lines
specified by this command. Using this command increases the
effective frame rate of the camera and also reduces the automatic
exposure time ( when shutter is disabled ). This command programs
the camera with the starting and ending line but does not turn on
windowing. In order to enable windowing, the
‘svm w’
command
must be issued.

svw <y1> <y2>
Parameter #1:
y1
The first line in the image.
Parameter #2:
y2
The last line in the image.
Range:
y1
min=1, max=camera dependent
y2
min=1, max=camera dependent
Example:
svw 10 120
Sets the vertical window from line# 10
to line# 120.
Notes:
When using this command it is necessary to adjust the
number of active lines in the frame grabber to the
value: y2-y1+1.
3.8.2.2 Get Vertical Window (

‘gvw’
command returns the current vertical area of interest
setting.
