myBluePixel = Pixel(0, 0, red=0, green=0, blue=255)
pixels = picture.getPixels()
pixels[0] = myBluePixel

Initialization

Pixel.Pixel(self, x, y, red, green, blue)

Parameters:

• x (int) – horizontal location of pixel.
• y (int) – vertical location of pixel.
• red (int) – degree of redness of pixel. Between 0 and 255 inclusive.
• green (int) – degree of greenness of pixel. Between 0 and 255 inclusive.
• blue (int) – degree of blueness of pixel. Between 0 and 255 inclusive.

Methods

Getters

Return the x value of a pixel.

Pixel.getX(self)

pixel = picture.getPixel(200, 10)

# This will print 200.
print(pixel.getX())

Return the y value of a pixel.

Pixel.getY(self)

pixel = picture.getPixel(200, 10)

# This will print 10.
print(pixel.getY())

This function returns the Color object of the pixel.

Pixel.getColor(self)

color = pixel.getColor()

These functions return the red, green, and blue values of the pixel.

Pixel.getRed(self)

red = pixel.getRed()

Pixel.getGreen(self)

green = pixel.getGreen()

Pixel.getBlue(self)

blue = pixel.getBlue()
