# Fonts
Buoyant currently supports two font systems:
1. **Embedded Graphics Monospace Fonts**: Fixed-width fonts from the `embedded-graphics` crate,
perfect for simple displays and consistent spacing.
2. **U8g2 Fonts**: A rich collection of fonts ported from the U8g2 library, offering more
variety in styles and sizes.
## Using Embedded Graphics Fonts
The `embedded-graphics` crate provides a selection of fixed-width fonts that work well
with Buoyant. These bitmapped fonts are easy to use and render quickly, making them ideal for
text in animation-heavy applications.

```rust,no_run
# extern crate buoyant;
# extern crate embedded_graphics;
# extern crate embedded_graphics_simulator;
# use embedded_graphics::{pixelcolor::Rgb888, prelude::*};
# use embedded_graphics_simulator::{OutputSettings, SimulatorDisplay, Window};
#
# const BACKGROUND_COLOR: Rgb888 = Rgb888::CSS_DARK_SLATE_GRAY;
# const DEFAULT_COLOR: Rgb888 = Rgb888::WHITE;
#
# fn main() {
# let mut window = Window::new("Example", &OutputSettings::default());
# let mut display: SimulatorDisplay<Rgb888> = SimulatorDisplay::new(Size::new(480, 320));
#
# display.clear(BACKGROUND_COLOR).unwrap();
#
# view()
# .as_drawable(display.size(), DEFAULT_COLOR, &mut ())
# .draw(&mut display)
# .unwrap();
#
# window.show_static(&display);
# }
#
use buoyant::view::prelude::*;
use embedded_graphics::mono_font::ascii::{FONT_10X20, FONT_6X10, FONT_9X15};
fn view() -> impl View<Rgb888, ()> {
VStack::new((
Text::new("Small (6x10)", &FONT_6X10)
.foreground_color(Rgb888::CSS_PALE_GREEN),
Text::new("Medium (9x15)", &FONT_9X15)
.foreground_color(Rgb888::CSS_LIGHT_SKY_BLUE),
Text::new("Large (10x20)", &FONT_10X20)
.foreground_color(Rgb888::CSS_LIGHT_CORAL),
))
.with_spacing(20)
.with_alignment(HorizontalAlignment::Center)
.flex_infinite_width(HorizontalAlignment::Center)
.padding(Edges::All, 20)
}
```
## Using U8g2 Fonts
For more font variety, Buoyant supports the U8g2 font collection through the [`u8g2-fonts`](https://crates.io/crates/u8g2-fonts)
crate. This gives you access to many different font styles and sizes, but at a greater
cost to render.
The original [u8g2 wiki](https://github.com/olikraus/u8g2/wiki/fntlistall)
is the best catalog to search for specific u8g2 fonts.

```rust,no_run
# extern crate buoyant;
# extern crate embedded_graphics;
# extern crate embedded_graphics_simulator;
# extern crate u8g2_fonts;
# use embedded_graphics::{pixelcolor::Rgb888, prelude::*};
# use embedded_graphics_simulator::{OutputSettings, SimulatorDisplay, Window};
#
# const BACKGROUND_COLOR: Rgb888 = Rgb888::CSS_DARK_SLATE_GRAY;
# const DEFAULT_COLOR: Rgb888 = Rgb888::WHITE;
#
# fn main() {
# let mut window = Window::new("Example", &OutputSettings::default());
# let mut display: SimulatorDisplay<Rgb888> = SimulatorDisplay::new(Size::new(480, 320));
#
# display.clear(BACKGROUND_COLOR).unwrap();
#
# view()
# .as_drawable(display.size(), DEFAULT_COLOR, &mut ())
# .draw(&mut display)
# .unwrap();
#
# window.show_static(&display);
# }
