Importing Images
================

Goals
-----

- Importing and drawing images (imported as ``pygame.Surface``)
- Extracting a ``pygame.Rect`` from the image to use as a game object (for collision and movement).
- Understand transparency (png) and the importance of cropping your image files.
    - ``pygame.Surface.set_alpha(int) -> None``
- Check pygame docs for various ``pygame.transform`` methods to use on ``pygame.Surface`` s.
    - ``pygame.transform.flip(surface: Surface, flip_x: bool, flip_y: bool) -> Surface``
    - ``pygame.transform.scale(surface: Surface, size: Tuple[int, int], dest_surface: Surface = None) -> Surface``
    - ``pygame.transform.rotate(surface: Surface, degrees: float) -> Surface``


Required Files
--------------

- :doc:`pygame-template`
- :download:`fishGreen.png <../images/fishGreen.png>` 

Video Tutorial
--------------
Not done yet, sorry.

What you need to do
-------------------

- When you click the fish make it grow. You will need to scale the image as well as update the ``fish_rect``.
- Add the ability to move the fish left and right with the keyboard.
- When the fish moves, flip the image to have the fish look in that direction.
