embedded-graphics 0.6.2

Embedded graphics library for small hardware displays

Embedded graphics

Embedded-graphics is a 2D graphics library that is focused on memory constrained embedded devices. It contains built in items that make it easy to draw 2D graphics primitives:

  • Primitive shapes with stroke and/or fill
    • Lines
    • Rectangles
    • Circles
    • Triangles
  • Images
    • Built in support for images from raw data
    • Other image formats, like BMP and TGA images, are supported using an external crate
  • Text

A core goal of embedded-graphics is to draw graphics without using any buffers; the crate is no_std compatible and works without a dynamic memory allocator, and without pre-allocating large chunks of memory. To achieve this, it takes an Iterator based approach, where pixel values and positions are calculated on the fly, with the minimum of saved state. This allows the consuming application to use far less RAM at little to no performance penalty.

To support many different kinds of display embedded-graphics doesn't include any drivers directly but provides an API that can be implemented by external crates. The display drivers section contains a list of display drivers with embedded-graphics support. In addition to the drivers for real displays the simulator can be used to test code during development.

Other functions of embedded-graphics are also designed to be extended by the application or other crates. Examples of this are adding support for different image formats or implementing custom Drawable items. The external crates section contains a list of crates that provide reusable extensions to embedded-graphics.

The following example uses the simulator to demonstrate some of the built in drawing functions:

use embedded_graphics::{
    fonts::{Font6x8, Text},
    primitives::{Circle, Rectangle, Triangle},
    style::{PrimitiveStyle, TextStyle},
use embedded_graphics_simulator::{
    BinaryColorTheme, OutputSettingsBuilder, SimulatorDisplay, Window,

fn main() -> Result<(), std::convert::Infallible> {
    // Create a new monochrome simulator display with 128x64 pixels.
    let mut display: SimulatorDisplay<BinaryColor> = SimulatorDisplay::new(Size::new(128, 64));

    // Create styles used by the drawing operations.
    let thin_stroke = PrimitiveStyle::with_stroke(BinaryColor::On, 1);
    let thick_stroke = PrimitiveStyle::with_stroke(BinaryColor::On, 3);
    let fill = PrimitiveStyle::with_fill(BinaryColor::On);
    let text_style = TextStyle::new(Font6x8, BinaryColor::On);

    let yoffset = 10;

    // Draw a 3px wide outline around the display.
    let bottom_right = Point::zero() + display.size() - Point::new(1, 1);
    Rectangle::new(Point::zero(), bottom_right)
        .draw(&mut display)?;

    // Draw a triangle.
        Point::new(16, 16 + yoffset),
        Point::new(16 + 16, 16 + yoffset),
        Point::new(16 + 8, yoffset),
    .draw(&mut display)?;

    // Draw a filled square
    Rectangle::new(Point::new(52, yoffset), Point::new(52 + 16, 16 + yoffset))
        .draw(&mut display)?;

    // Draw a circle with a 3px wide stroke.
    Circle::new(Point::new(96, yoffset + 8), 8)
        .draw(&mut display)?;

    // Draw centered text.
    let text = "embedded-graphics";
    let width = text.len() as i32 * 6;
    Text::new(text, Point::new(64 - width / 2, 40))
        .draw(&mut display)?;

    let output_settings = OutputSettingsBuilder::new()
    Window::new("Hello World", &output_settings).show_static(&display);


This example is also included in the simulator crate and can be run using cargo run --example hello-world.

Using macros

Embedded graphics defines macros to easily build drawables and styles for primitives and texts:

use embedded_graphics::fonts::Font6x8;
use embedded_graphics::pixelcolor::Rgb565;
use embedded_graphics::prelude::*;
use embedded_graphics::{
    egcircle, egline, egrectangle, egtext, egtriangle, primitive_style, text_style,

// Only used for examples - this would be replaced by the driver for your chosen display
use embedded_graphics::mock_display::MockDisplay as Display;

fn main() {
    // Create a display object to draw into
    // This will be whichever display driver you decide to use, like the SSD1306, SSD1351, etc
    let mut display = Display::new();

    // Draw a circle centered at (64, 64) with a radius of 64 and a white 1px stroke
        center = (64, 64),
        radius = 64,
        style = primitive_style!(stroke_color = Rgb565::WHITE)
    .draw(&mut display);

    // Draw a 1px thick white line from (64, 64) to (0, 64)
        start = (64, 64),
        end = (0, 64),
        style = primitive_style!(stroke_color = Rgb565::WHITE)
    .draw(&mut display);

    // Draw a 1px red line from (64, 64) to (80, 80)
        start = (64, 64),
        end = (80, 80),
        style = primitive_style!(stroke_color = Rgb565::RED)
    .draw(&mut display);

    // Draw a rectangle from (64, 64) to (80, 80) with a black fill
        top_left = (64, 64),
        bottom_right = (80, 80),
        style = primitive_style!(fill_color = Rgb565::BLACK)
    .draw(&mut display);

    // Print "Hello world!" in a white 6x8 pixel font with the top left corner positioned at (5, 50)
        text = "Hello world!",
        top_left = (5, 50),
        style = text_style!(font = Font6x8, text_color = Rgb565::WHITE)
    .draw(&mut display);
