Struct imgui::FontAtlas[][src]

#[repr(C)]pub struct FontAtlas {
    pub flags: FontAtlasFlags,
    pub tex_id: TextureId,
    pub tex_desired_width: i32,
    pub tex_glyph_padding: i32,
    // some fields omitted
}

A font atlas that builds a single texture

Fields

flags: FontAtlasFlags

Configuration flags

tex_id: TextureId

Texture identifier

tex_desired_width: i32

Texture width desired by user before building the atlas.

Must be a power-of-two. If you have many glyphs and your graphics API has texture size restrictions, you may want to increase texture width to decrease the height.

tex_glyph_padding: i32

Padding between glyphs within texture in pixels.

Defaults to 1. If your rendering method doesn't rely on bilinear filtering, you may set this to 0.

Implementations

impl FontAtlas[src]

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

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

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

pub fn is_built(&self) -> bool[src]

Returns true if the font atlas has been built

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

Builds a 1 byte per-pixel font atlas texture

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

Builds a 4 byte per-pixel font atlas texture

pub fn clear(&mut self)[src]

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

pub fn clear_fonts(&mut self)[src]

Clears output font data (glyph storage, UV coordinates)

pub fn clear_tex_data(&mut self)[src]

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)[src]

Clears all the data used to build the textures and fonts
