Enter a
•
positive value
from 0...HeightOfImage to specify a position relative to
the top of the image. LinePos=0 specifies the very first image line.
•
negative value
from -1...-HeightOfImage to specify a position relative
to the bottom of the image. LinePos=-1 specifies the very last image
line.
SIS
UserValue
can be written into the camera’s image. In sequence mode for
every sequence entry an own SIS
UserValue
can be written.
Note
L
SIS outside the visible image area:
For certain Format_7 modes the image frame transported may
contain padding (filling) data at the end of the transported
frame. Setting LinePos=HeightOfImage places the stamp in
this padding data area, outside the visible area (invisible
SIS).
If the transported image frame does not contain any padding
data the camera will not relocate the SIS to the visible area
automatically (no SIS).
Take in mind that the accuracy of the time stamp might be
affected by asynchronous traffic – mainly if image settings
are changed.
