StrobePos Parameter
StrobePos is expressed as a percentage of the expose width pulse.
A value of 0 % establishes the earliest position. The leading edge of strobe pulse is simultaneous with the beginning of exposure.
A value of 100 % establishes the latest position. The trailing edges of strobe pulse and exposure are simultaneous.
A value of 50 % means that the strobe pulse is located in the middle of the exposure period.
In any situation, the strobe pulse is issued during the exposure period.
