Method Details

getX

public int getX()

Gets the x coordinate of this Pixel in the image.

Examples

Pixel currentPixel = imagePixels[10][20];
int xLocation = currentPixel.getX();
System.out.println("This pixel is located at x position " + xLocation);

Output:

This pixel is located at x position 20

getY

public int getY()

Gets the y coordinate of this Pixel in the image.

Examples

Pixel currentPixel = imagePixels[10][20];
int yLocation = currentPixel.getY();
System.out.println("This pixel is located at y position " + yLocation);

Output:

This pixel is located at y position 10

getSourceImage

public Image getSourceImage()

Gets the image that this Pixel is part of.

Examples

Pixel currentPixel = imagePixels[10][20];
Image sourceImage = currentPixel.getSourceImage();

getColor

public Color getColor()

Gets the color of the Pixel in the image.

Examples

Pixel currentPixel = imagePixels[10][20];
Color pixelColor = currentPixel.getColor();

setColor

public void setColor(Color color)

Sets the color of this Pixel in the image to the specified Color.

Parameters

Name	Type	Required?	Description
color	Color		the color to set this `Pixel`

Examples

for (int row = 0; row < pixels.length; row++) {
