Pixel

java.lang.Object
- Pixel

All Implemented Interfaces:

java.lang.Comparable<Pixel>
```
public class Pixel
extends java.lang.Object
implements java.lang.Comparable<Pixel>
```
A point of color.
Pixels are represented as three integral color components (red, green, and blue) in the inclusive range [0, 255]. Lower values mean less color; higher mean more. For example, new Pixel(255,255,255) represents white, new Pixel(0,0,0) represents black, and new Pixel(0,255,0) represents green.
This data structure is immutable. Once a Pixel is created, it cannot be modified.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`int`	`compareTo(Pixel o)`
`int`	`distance(Pixel px)` Determines the level of similarity between this pixel and another by summing the absolute values of the differences between corresponding components of the two pixels.
`boolean`	`equals(java.lang.Object other)` Checks whether this pixel has the same components as the given Object.
`boolean`	`equals(Pixel px)` Compares the RGB values of the current Pixel with another to check if they are the same (and thus whether the two Pixels equal each other)
`int`	`getBlue()` Accessor for the blue component of the pixel.
`int[]`	`getComponents()` Accessor for the pixel's components as an array of 3 integers, where index 0 is red, index 1 is green, and index 2 is blue.
`int`	`getGreen()` Accessor for the green component of the pixel.
`int`	`getRed()` Accessor for the red component of the pixel.
`int`	`hashCode()`
`java.lang.String`	`toString()` Returns a string representation of this pixel.

- Field Detail
  - BLACK
```
public static final Pixel BLACK
```
    The Pixel representing the RGB color black.
  - BLUE
```
public static final Pixel BLUE
```
    The Pixel representing the RGB color blue.
  - RED
```
public static final Pixel RED
```
    The Pixel representing the RGB color red.
  - GREEN
```
public static final Pixel GREEN
```
    The Pixel representing the RGB color green.
  - WHITE
```
public static final Pixel WHITE
```
    The Pixel representing the RGB color white.
- Method Detail
  - getRed
```
public int getRed()
```
    Accessor for the red component of the pixel.
    
    Returns:
    
    the int value of the red component
  - getGreen
```
public int getGreen()
```
    Accessor for the green component of the pixel.
    
    Returns:
    
    the int value of the green component
  - getBlue
```
public int getBlue()
```
    Accessor for the blue component of the pixel.
    
    Returns:
    
    the int value of the blue component
  - getComponents
```
public int[] getComponents()
```
    Accessor for the pixel's components as an array of 3 integers, where index 0 is red, index 1 is green, and index 2 is blue.
    
    Returns:
    
    an int array representing the pixel's components
  - distance
```
public int distance(Pixel px)
```
    Determines the level of similarity between this pixel and another by summing the absolute values of the differences between corresponding components of the two pixels. Hint: use Math.abs
    
    Parameters:
    
    px - the other pixel with which to compare
    
    Returns:
    
    the sum of the differences in each of the color components
  - toString
```
public java.lang.String toString()
```
    Returns a string representation of this pixel. The string should comma separate the rgb values and surround them with parentheses.
    For example, RED.toString() is "(255, 0, 0)"
    Note: This function will allow you to print pixels in a readable format. This can be very helpful while debugging, and we highly encourage you to use print statements to aid your debugging throughout this assignment.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    a string representation of this pixel
  - equals
```
public boolean equals(Pixel px)
```
    Compares the RGB values of the current Pixel with another to check if they are the same (and thus whether the two Pixels equal each other)
    
    Parameters:
    
    px - The pixel being compared with this
  - equals
```
public boolean equals(java.lang.Object other)
```
    Checks whether this pixel has the same components as the given Object. If the other object is not a Pixel, then the method returns false.
    
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class java.lang.Object
  - compareTo
```
public int compareTo(Pixel o)
```
    Specified by:
    
    compareTo in interface java.lang.Comparable<Pixel>
