                       float minLp,
                       float maxLp)

create a lens with a given maximum magnification factor

Parameters:

mm - maximum magnification factor, mm in [0,+inf[

LPDGaussianLens

public LPDGaussianLens(float mm,
                       float lp,
                       float minLp,
                       float maxLp,
                       int outerRadius,
                       int innerRadius)

create a lens with a given maximum magnification factor, inner and outer radii

Parameters:

outerRadius - outer radius (beyond which no magnification is applied - outward)

innerRadius - inner radius (beyond which maximum magnification is applied - inward)

LPDGaussianLens

public LPDGaussianLens(float mm,
                       float lp,
