Show an image file.
|

You can specify its placement either using ``alignment`` or by specifying a ``coordinate``, but not both.
|
|
|
|
Arguments:
|
|
file_name (str): Path to the image file. Paths may be absolute or relative from the project folder.
|
|
alignment (Align): Where to place the image (*Default*: Align.center).
|
|
coordinate (tuple): ``(x, y)`` coordinate tuple. It is the top-left corner of the image (*Default*: None).
|
|
clear (bool): Whether to clear the screen before showing the image (*Default*: ``True``).
|
|
|
|
Example::
|
|
|
|
# Show a built-in image showing two eyes looking upward
|
|
brick.display.image(Image.up)
|
|
|
|
# Display a custom image from your project folder
|
|
brick.display.image('pybricks.png')
|
|
|
|
# Display a custom image image at the top right of the screen, without clearing
|
|
# the screen first
|
|
brick.display.image('arrow.png', Align.top_right, clear=False)
