• p – another Pixel

Returns:

euclidean distance between these pixels [px]

distance_to_sq

public int distance_to_sq(Pixel p)

Calculates squared distance to another pixel

Parameters:

• p – another Pixel

Returns:

squared distance between these pixels [px2]

getSignature

public double getSignature()

Returns this pixel’s signature

Returns:relative brightness of this pixel due to an emitter [-]

setSignature

public void setSignature(double signature)

Set’s the pixel’s signature.
