in the particle. 

cwimaqMeasurementAverageVertSegmentLength

Average length of a vertical segment in 
the particle. 

cwimaqMeasurementBoundingRectBottom

Y-coordinate of the lowest particle point. 

cwimaqMeasurementBoundingRectDiagonal

Distance between opposite corners of 
the bounding rectangle. 

cwimaqMeasurementBoundingRectHeight

Distance between the Y-coordinate 
of highest particle point and the 
Y-coordinate of the lowest particle point. 

cwimaqMeasurementBoundingRectLeft

X-coordinate of the leftmost particle 
point. 

cwimaqMeasurementBoundingRectRight

X-coordinate of the rightmost particle 
point. 

cwimaqMeasurementBoundingRectTop

Y-coordinate of highest particle point. 

cwimaqMeasurementBoundingRectWidth

Distance between the X-coordinate 
of the leftmost particle point and the 
X-coordinate of the rightmost particle 
point. 

cwimaqMeasurementCenterMassX

X-coordinate of the point representing 
the average position of the total particle 
mass assuming every point in the 
particle has a constant density. 

cwimaqMeasurementCenterMassY

Y-coordinate of the point representing 
the average position of the total particle 
mass assuming every point in the 
particle has a constant density. 

cwimaqMeasurementCompactnessFactor

Area divided by the product of 
Bounding Rect Width and Bounding 
Rect Height. 

cwimaqMeasurementConvexHullArea

Area of the smallest convex polygon 
containing all points in the particle.
