All Implemented Interfaces:

ContourPlot.PixelBase

Enclosing class:

ContourPlot
```
public class ContourPlot.Pixel
extends java.lang.Object
implements ContourPlot.PixelBase
```
Pixel class for retrieving a value from an ContourPlot.Img. A Pixel object stores a position and can be used to get and set values of an Img. It is NOT the value and changing its position will not change the image, instead it will reference a different value of the image as the pixel object is a pointer to a value in the Img's data array.
The Pixel class also provides a set of static methods for color decomposition and recombination from color channels like argb(int, int, int, int) or a(int), r(int), g(int), b(int).

                         int blueWeight)
```
    Calculates a grey value from an RGB or ARGB value using specified weights for each R,G and B channel.
    Weights are integer values so normalized weights need to be converted beforehand. E.g. normalized weights (0.33, 0.62, 0.05) would be have to be converted to integer weights (33, 62, 5).
    When using weights with same signs, the value is within [0..255]. When weights have mixed signs the resulting value is unbounded.
    
    Parameters:
    
    color - RGB(24bit) or ARGB(32bit) value
    
    redWeight - weight for red channel
    
    greenWeight - weight for green channel
