computeAdjustmentFactorsFor255Scale

public void computeAdjustmentFactorsFor255Scale()

This is called when a 3x3 submatrix is stored in the upper left corner, and you want to use homogenous color transforms to offset the multiplication into the dynamic range of a byte (i.e., 0..255).

For example:
a[0][3] = 255 - (f(a[0][0]) + f(a[0][1]) + f(a[0][2]));
a[1][3] = 255 - (f(a[1][0]) + f(a[1][1]) + f(a[1][2]));
a[2][3] = 255 - (f(a[2][0]) + f(a[2][1]) + f(a[2][2]));
a[3][3] = 1; where f return a00*255 if a00 >0 else 0;
