pub fn load_brushes( &mut self, font: &Font, brushes: impl AsRef<str>, ) -> &mut Self

Load additional brushes from a font

let font = include_bytes!("../docs/unifont-15.0.01.ttf");
let font = fontdue::Font::from_bytes(font.as_ref(), fontdue::FontSettings::default())
 .expect("tried and tested included font");
let mut insa = insa::Insa::default();
insa.load_brushes(&font, ".oO8°");
println!("{insa:?}")

pub fn brushes(&self) -> &BrushMap

ref access the internal brush map

pub fn brushes_mut(&mut self) -> &mut BrushMap

Mut access internal brush map

pub fn invert(&self) -> bool

Does Insa invert dark/light?

pub fn invert_mut(&mut self) -> &mut bool

Mut access to - does Insa invert dark/light?

pub fn set_invert(&mut self, invert: bool) -> &mut Self

Should Insa invert dark/light?

pub fn fixed_background(&self) -> Option<(u8, u8, u8)>

Does Insa invert dark/light?

pub fn fixed_background_mut(&mut self) -> Option<&mut (u8, u8, u8)>
