Struct FontAtlas

pub struct FontAtlas(/* private fields */);

Implementations

impl FontAtlas

pub fn get(&self) -> &ImFontAtlas

Gets a reference to the native wrapper struct.

impl FontAtlas

pub fn cast(r: &ImFontAtlas) -> &FontAtlas

Converts a native reference into a wrapper reference.

pub fn cast_mut(r: &mut ImFontAtlas) -> &mut FontAtlas

Converts a native reference into a wrapper reference.

It is safe because if you have a reference to the native reference, you already can change anything.

impl FontAtlas

pub unsafe fn texture_ref(&self) -> ImTextureRef

pub unsafe fn inner(&mut self) -> &mut ImFontAtlas

pub fn current_texture_unique_id(&self) -> TextureUniqueId

pub fn check_texture_unique_id(&self, uid: TextureUniqueId) -> bool

pub fn get_texture_by_unique_id( &self, uid: TextureUniqueId, ) -> Option<TextureId>

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 remove_font(&mut self, font_id: FontId)

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

Adds an arbitrary image to the font atlas.

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

pub fn remove_custom_rect(&mut self, idx: CustomRectIndex)

Methods from Deref<Target = ImFontAtlas>

pub unsafe fn GetCustomRect(&self, id: i32, out_r: *mut ImFontAtlasRect) -> bool

Trait Implementations

impl Debug for FontAtlas

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for FontAtlas

type Target = ImFontAtlas

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
