Member Function Documentation

setWrapAround()

void CentroidDetection::setWrapAround

(

unsigned int

n

)

Set how many of the values at the beginning of rawData can be joined in a single centroid with those at the end of rawData if a centroid is detected across them. Useful for ring-like devices.

setMultiplierBits()

void CentroidDetection::setMultiplierBits

(

unsigned int

n

)

How many extra bits to use during the fixed-point multiplication that computes the centroids position. Defaults to 7.
