Struct easy_imgui::FontAtlasMut

pub struct FontAtlasMut<'ui, A: ?Sized> { /* private fields */ }

Implementations

impl<'ui, A> FontAtlasMut<'ui, A>

A reference to the font altas that is to be built.

You get a value of this type when implementing UiBuilder::build_custom_atlas. If you want that function to be called again, call Context::invalidate_font_atlas.

pub fn add_font(&mut self, font: FontInfo) -> FontId

Adds the given font to the atlas.

It returns the id to use this font. FontId implements Pushable so you can use it with Ui::with_push.

pub fn add_font_collection( &mut self, fonts: impl IntoIterator<Item = FontInfo> ) -> FontId

Adds several fonts with as a single ImGui font.

This is useful mainly if different TTF files have different charset coverage but you want to use them all as a unit.

pub fn add_custom_rect_font_glyph( &mut self, font: FontId, id: char, size: impl Into<Vector2<u32>>, advance_x: f32, offset: Vector2, draw: impl FnOnce(&mut A, &mut SubImage<&'_ mut ImageBuffer<Rgba<u8>, &'_ mut [u8]>>) + 'static ) -> CustomRectIndex

Adds an image as a substitution for a character in a font.

pub fn add_custom_rect_regular( &mut self, size: impl Into<Vector2<u32>>, draw: impl FnOnce(&mut A, &mut SubImage<&'_ mut ImageBuffer<Rgba<u8>, &'_ mut [u8]>>) + 'static ) -> CustomRectIndex

Adds an arbitrary image to the font atlas.

The returned CustomRectIndex can be used later to draw the image.

Trait Implementations

impl<'ui, A> Deref for FontAtlasMut<'ui, A>

type Target = FontAtlasPtr<'ui>

fn deref(&self) -> &FontAtlasPtr<'ui>

Dereferences the value.
