5.2.12 Absolute Coordinates

The 3D coordinates are given relative to the start of the 3D ROI as a default.
When the property Peak0_EnAbsCoordinate is set to True then the 3D coordinates are given
relative to the value of the property Peak0_AbsCoordinateBase. This is useful if the 3D-ROI is not
kept constant.
Example: Peak0_EnAbsCoordinate = True, Peak0_AbsCoordinateBase = 0, Peak0_3DY=200: If the peak
is detected in row 50 of the ROI, the value 250 (50+Peak0_3DY) would be given as resulting 3D
coordinate.
The value of Peak0_AbsCoordinateBase must fulfill the following conditions:
(Peak0_AbsCoordinateBase <= Peak0_3DY) and (Peak0_AbsCoordinateBase + 1024 >=
Peak0_3DY + Peak0_3DH).
MirrorPeak and absolute coordinates
If Peak0_Mirror =True and Peak0_EnAbsCoordinate = True then the formula to calculate the 3D
coordinate is:
c' = MAX_H + Peak0_AbsCoordinateBase - Peak0_3DY - c - 1,
where c is the original (relative) coordinate without mirroring. MAX_H=1024. This is the same as
mirroring in a ROI with Y=Peak0_AbsCoordinateBase and H=MAX_H.
