//! Embedded-graphics is a 2D graphics library that is focused on memory constrained embedded devices.
//!
//! 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
//! colors 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.
//!
//! It contains built in items that make it easy to draw 2D graphics primitives:
//!
//! * [Raw data images](./image/struct.ImageRaw.html)
//! * [Primitives](./primitives/index.html)
//!     * [Lines](./primitives/line/struct.Line.html)
//!     * [Rectangles (and squares)](./primitives/rectangle/struct.Rectangle.html)
//!     * [Circles](./primitives/circle/struct.Circle.html)
//!     * [Ellipses](./primitives/ellipse/struct.Ellipse.html)
//!     * [Arcs](./primitives/arc/struct.Arc.html)
//!     * [Sectors](./primitives/sector/struct.Sector.html)
//!     * [Triangles](./primitives/triangle/struct.Triangle.html)
//!     * [Polylines](./primitives/polyline/struct.Polyline.html)
//!     * [Rounded rectangles](./primitives/rounded_rectangle/struct.RoundedRectangle.html)
//! * [Text](./text/index.html)
//! * [Monospaced fonts](./mono_font/index.html)
//!
//! # Additional functions provided by external crates
//!
//! Embedded-graphics is designed to be extended by the application or other crates. Examples of
//! this are adding support for different image formats or implementing custom fonts.
//!
//! * [BMP images - `tinybmp`](https://crates.io/crates/tinybmp)
//! * [TGA images - `tinytga`](https://crates.io/crates/tinytga)
//! * [ProFont monospace font - `profont`](https://crates.io/crates/profont)
//! * [Picofont Pico8 font - `embedded-picofont`](https://crates.io/crates/embedded_picofont)
//! * [IBM437 font - `ibm437`](https://crates.io/crates/ibm437)
//! * [Simple layout/alignment functions - `embedded-layout`](https://crates.io/crates/embedded-layout)
//! * [TextBox with text alignment options - `embedded-text`](https://crates.io/crates/embedded-text)
//! * [Heapless plotting library for small embedded targets - `embedded-plots`](https://crates.io/crates/embedded-plots)
//!
//! Note that some of these crates may not support the latest version of embedded-graphics.
//!
//! If you know of a crate that is not in this list, please [open an
//! issue](https://github.com/embedded-graphics/embedded-graphics/issues/new) to add it.
//!
//! # Display drivers
//!
//! To support many different kinds of display, embedded-graphics doesn't include any drivers
//! directly but provides the [`DrawTarget`] API in [`embedded-graphics-core`] that can be
//! implemented by external crates. In addition to the drivers for real displays, the
//! [simulator](https://docs.rs/embedded-graphics-simulator/) can be used to test code during
//! development.
//!
//! ![Photographs showing embedded-graphics running on physical display hardware.](https://raw.githubusercontent.com/embedded-graphics/embedded-graphics/4c680418cc4c37b8f7ed92d8b26edfde880d4c96/assets/banner-photo.jpg)
//!
//! These are just some of the displays the community has added embedded-graphics support to. This
//! list is taken from the [dependent crates
//! list](https://crates.io/crates/embedded-graphics/reverse_dependencies) on crates.io so might be
//! missing some unpublished entries. Please [open an
//! issue](https://github.com/embedded-graphics/embedded-graphics/issues/new) if there's a display driver
//! that should be added to this list.

//! # Simulator
//!
//! Embedded graphics comes with a [simulator]! The simulator can be used to test and debug
//! embedded graphics code, or produce examples and interactive demos to show off embedded graphics
//! features.
//!
//! ![A screenshot of embedded-graphics running in its simulator.](https://raw.githubusercontent.com/embedded-graphics/embedded-graphics/4c680418cc4c37b8f7ed92d8b26edfde880d4c96/assets/simulator-demo.png)
//!
//! Take a look at the [examples repository](https://github.com/embedded-graphics/examples) to see what
//! embedded-graphics can do, and how it might look on a display. You can run the examples like
//! this:
//!
//! ```bash
//! git clone https://github.com/embedded-graphics/examples.git
//! cd examples
//!
//! cargo run --example hello-world
//! ```
//!
//! # Crate features
//!
//! Additional features can be enabled by adding the following features to your `Cargo.toml`.
//!
//! * `nalgebra_support` - use the [Nalgebra](https://crates.io/crates/nalgebra) crate with `no_std`
//! support to enable conversions from `nalgebra::Vector2` to [`Point`] and [`Size`].
//!
//! * `fixed_point` - use fixed point arithmetic instead of floating point for all trigonometric
//! calculation.
//!
//! # Migrating from older versions

//!
//! # Implementing `embedded_graphics` support for a display driver
//!
//! To add support for embedded-graphics to a display driver, [`DrawTarget`] from
//! [`embedded-graphics-core`] must be implemented. This allows all embedded-graphics items to be
//! rendered by the display. See the [`DrawTarget`] documentation for implementation details.
//!
//! # Examples
//!
//! ## Drawing examples
//!
//! [![A grid of screenshots showing primitives, text and other items that can be drawn using embedded-graphics.](https://raw.githubusercontent.com/embedded-graphics/embedded-graphics/4c680418cc4c37b8f7ed92d8b26edfde880d4c96/doc/assets/all_drawing_ops.png)](./examples/index.html)
//!
//! Example usage of drawing primitives, text and images with embedded-graphics can be found [here](./examples/index.html).
//!
//! ## Shapes and text
//!
//! The following example draws some shapes and text to a [`MockDisplay`] in place of target
//! hardware. The [simulator](https://docs.rs/embedded-graphics-simulator/) can also be used for
//! debugging, development or if hardware is not available.
//!
//! ```rust,no_run
//! use embedded_graphics::{
//!     mono_font::{ascii::FONT_6X10, MonoTextStyle},
//!     pixelcolor::BinaryColor,
//!     prelude::*,
//!     primitives::{
//!         Circle, PrimitiveStyle, PrimitiveStyleBuilder, Rectangle, StrokeAlignment, Triangle,
//!     },
//!     text::{Alignment, Text},
//!     mock_display::MockDisplay,
//! };
//!
//! fn main() -> Result<(), std::convert::Infallible> {
//!     // Create a new mock display
//!     let mut display: MockDisplay<BinaryColor> = MockDisplay::new();
//! #   display.set_allow_overdraw(true);
//!
//!     // 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 border_stroke = PrimitiveStyleBuilder::new()
//!         .stroke_color(BinaryColor::On)
//!         .stroke_width(3)
//!         .stroke_alignment(StrokeAlignment::Inside)
//!         .build();
//!     let fill = PrimitiveStyle::with_fill(BinaryColor::On);
//!     let character_style = MonoTextStyle::new(&FONT_6X10, BinaryColor::On);
//!
//!     let yoffset = 10;
//!
//!     // Draw a 3px wide outline around the display.
//!     display
//!         .bounding_box()
//!         .into_styled(border_stroke)
//!         .draw(&mut display)?;
//!
//!     // Draw a triangle.
//!     Triangle::new(
//!         Point::new(16, 16 + yoffset),
//!         Point::new(16 + 16, 16 + yoffset),
//!         Point::new(16 + 8, yoffset),
//!     )
//!     .into_styled(thin_stroke)
//!     .draw(&mut display)?;
//!
//!     // Draw a filled square
//!     Rectangle::new(Point::new(52, yoffset), Size::new(16, 16))
//!         .into_styled(fill)
//!         .draw(&mut display)?;
//!
//!     // Draw a circle with a 3px wide stroke.
//!     Circle::new(Point::new(88, yoffset), 17)
//!         .into_styled(thick_stroke)
//!         .draw(&mut display)?;
//!
//!     // Draw centered text.
//!     let text = "embedded-graphics";
//!     Text::with_alignment(
//!         text,
//!         display.bounding_box().center() + Point::new(0, 15),
//!         character_style,
//!         Alignment::Center,
//!     )
//!     .draw(&mut display)?;
//!
//!     Ok(())
//! }
//! ```
//!
//! This example is also included in the [examples](https://github.com/embedded-graphics/examples) repository and
//! can be run using `cargo run --example hello-world`. It produces this output:
