Remarks

Every line must have a starting point and ending point. The PixelY1 and PixelY2 results represent the Y
coordinate position starting (Y1) and endpoints (Y2) of the specified Line object. Since Line object
starting and endpoints can be assigned to other vision objects, the (PixelX1, PixelY1) and (PixelX2,
PixelY2) coordinate pairs can actually be pixel coordinate positions which match the PixelX and PixelY
results for other vision objects. (In other words if a Line object's starting point is defined by a Correlation
object, then the (PixelX, PixelY) results from the Correlation object will match the (PixelX1, PixelY1)
results for the Line object.)
