adafruit-circuitpython-display-shapes 2.8.2

Various common shapes for use with displayio

Introduction

Various common shapes for use with displayio

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-display_shapes

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-display_shapes

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-display_shapes

Usage Example

import board
import displayio
from adafruit_display_shapes.rect import Rect
from adafruit_display_shapes.circle import Circle
from adafruit_display_shapes.arc import Arc
from adafruit_display_shapes.roundrect import RoundRect

splash = displayio.Group()
board.DISPLAY.root_group = splash

color_bitmap = displayio.Bitmap(320, 240, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0xFFFFFF
bg_sprite = displayio.TileGrid(color_bitmap, pixel_shader=color_palette, position=(0, 0))
print(bg_sprite.position)
splash.append(bg_sprite)

triangle = Triangle(170, 50, 120, 140, 210, 160, fill=0x00FF00, outline=0xFF00FF)
splash.append(triangle)

rect = Rect(80, 20, 41, 41, fill=0x0)
splash.append(rect)

circle = Circle(100, 100, 20, fill=0x00FF00, outline=0xFF00FF)
splash.append(circle)

arc = Arc(x=100, y=100, radius=25, angle=45, direction=90, segments=10, outline=0x00FF00)
splash.append(arc)

rect2 = Rect(50, 100, 61, 81, outline=0x0, stroke=3)
splash.append(rect2)

roundrect = RoundRect(10, 10, 61, 81, 10, fill=0x0, outline=0xFF00FF, stroke=6)
splash.append(roundrect)

while True:
    pass

Building locally

Zip release files

To build this library locally you’ll need to install the circuitpython-build-tools package.

python3 -m venv .venv
source .venv/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .venv/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix adafruit-circuitpython-display_shapes --library_location .

Sphinx documentation

Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):

python3 -m venv .venv
source .venv/bin/activate
pip install Sphinx sphinx-rtd-theme

Now, once you have the virtual environment activated:

cd docs
sphinx-build -E -W -b html . _build/html

This will output the documentation to docs/_build/html. Open the index.html in your browser to view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to locally verify it will pass.
