Struct imgui::SharedFontAtlas

pub struct SharedFontAtlas(_);

A font atlas that can be shared between contexts

Implementations

impl SharedFontAtlas

pub fn create() -> SharedFontAtlas

Methods from Deref<Target = FontAtlas>

pub fn add_font(&mut self, font_sources: &[FontSource<'_>]) -> FontId

pub fn fonts(&self) -> Vec<FontId>

pub fn get_font(&self, id: FontId) -> Option<&Font>

pub fn is_built(&self) -> bool

Returns true if the font atlas has been built

pub fn build_alpha8_texture(&mut self) -> FontAtlasTexture<'_>

Builds a 1 byte per-pixel font atlas texture

pub fn build_rgba32_texture(&mut self) -> FontAtlasTexture<'_>

Builds a 4 byte per-pixel font atlas texture

pub fn clear(&mut self)

Clears the font atlas completely (both input and output data)

pub fn clear_fonts(&mut self)

Clears output font data (glyph storage, UV coordinates)

pub fn clear_tex_data(&mut self)

Clears output texture data.

Can be used to save RAM once the texture has been transferred to the GPU.

pub fn clear_input_data(&mut self)

Clears all the data used to build the textures and fonts
