image

The Image class also has the following built-in instances of itself included as its attributes (the attribute names indicate what the image represents). In this example we will randomly display an image on the led matrix when the button a is pressed

Code

[codesyntax lang=”python”]

from microbit import *

import random

image_array = [Image.HEART, Image.HEART_SMALL, Image.HAPPY, Image.SMILE, Image.SAD,
Image.CONFUSED, Image.ANGRY, Image.ASLEEP, Image.SURPRISED, Image.SILLY, Image.FABULOUS,
Image.MEH, Image.YES, Image.NO, Image.CLOCK12, Image.CLOCK11, Image.CLOCK10, Image.CLOCK9,
Image.CLOCK8, Image.CLOCK7, Image.CLOCK6, Image.CLOCK5, Image.CLOCK4, Image.CLOCK3,
Image.CLOCK2, Image.CLOCK1, Image.ARROW_N, Image.ARROW_NE, Image.ARROW_E, Image.ARROW_SE,
Image.ARROW_S, Image.ARROW_SW, Image.ARROW_W, Image.ARROW_NW, Image.TRIANGLE,
Image.TRIANGLE_LEFT, Image.CHESSBOARD, Image.DIAMOND, Image.DIAMOND_SMALL, Image.SQUARE,
Image.SQUARE_SMALL, Image.RABBIT, Image.COW, Image.MUSIC_CROTCHET, Image.MUSIC_QUAVER,
Image.MUSIC_QUAVERS, Image.PITCHFORK, Image.XMAS, Image.PACMAN, Image.TARGET, Image.TSHIRT,
Image.ROLLERSKATE, Image.DUCK, Image.HOUSE, Image.TORTOISE,Image.BUTTERFLY,
Image.STICKFIGURE, Image.GHOST, Image.SWORD, Image.GIRAFFE, Image.SKULL,
Image.UMBRELLA, Image.SNAKE]

while True:
    if button_a.is_pressed():
        display.show(random.choice(image_array))
        sleep(1000)
    else:
        display.clear()

Here we show you how to create a custom image on the led matrix, we use the Mu editor – http://codewith.mu/

[codesyntax lang=”python”]

from microbit import *
im = Image(‘99999:90009:90009:90009:99999:’)
display.show(im)

[/codesyntax]

You can vary the brightness by changing the value of the digits from 0 – 9.

[codesyntax lang=”python”]

from microbit import *
im = Image(‘99999:96369:96369:96369:99999:’)
display.show(im)

[/codesyntax]

A simple animation example

[codesyntax lang=”python”]

from microbit import *

imgs = [
Image(‘90000:00000:00000:00000:00000:’),
Image(‘00000:09000:00000:00000:00000:’),
Image(‘00000:00000:00900:00000:00000:’),
Image(‘00000:00000:00000:00090:00000:’),
Image(‘00000:00000:00000:00000:00009:’)
]

display.show(imgs, delay=1000,loop=True)

[/codesyntax]
You can also set a pixel and move it around

[codesyntax lang=”python”]

from microbit import *

img = Image('00000:00000:00900:00000:00000:')
display.show(img)
sleep(1000)

while True:
img = img.shift_up(2)
display.show(img)
sleep(1000)
img = img.shift_right(2)
display.show(img)
sleep(1000)
img = img.shift_down(2)
display.show(img)
sleep(1000)
img = img.shift_left(2)
display.show(img)
sleep(1000)

[/codesyntax]
shift_left(n)

Return a new image created by shifting the picture left by n columns.

shift_right(n)

Same as image.shift_left(-n).

shift_up(n)

Return a new image created by shifting the picture up by n rows.

shift_down(n)

Same as image.shift_up(-n).
