WriteCropping (ByVal Rt As RECT) As Integer
ReadCropping (ByRef Rt As RECT) As Integer
Parameter(s)
Rt
A rectangle setting cropping the sensor image. The rectan-
gle must be located inside the sensor image, and actual
image starts from [Rt.left, Rt.top] with width of [Rt.right –
Rt.left] and height [Rt.bottom – Rt.top]. Actual image width
must be a multiple of 16 pixels and actual height even. If
sensor source is interlace, the top value in Rt must be even.
