Method Details

linearInterp

public static double linearInterp(double xa,
 double ya,
 double xb,
 double yb,
 double x)

solves the equation (yb-ya)/(xb-xa) = (y-ya)/(x-xa) for y given x. Useful for finding the pixel for a value given the dimension of the area and the range of values it is supposed to cover. Note, this does not check for xa == xb, in which case a divide by zero would occur.

slopeIntercept

public static double[] slopeIntercept(double xa,
 double ya,
 double xb,
 double yb)
