Struct glium_text_rusttype::FontTexture

pub struct FontTexture { /* fields omitted */ }

Texture which contains the characters of the font.

Methods

impl FontTexture

pub fn ascii_character_list() -> Vec<char>

Vec of complete ASCII range (from 0 to 255 bytes)

pub fn new<R, F, I>(
    facade: &F,
    font: R,
    font_size: u32,
    characters_list: I
) -> Result<FontTexture, Error> where
    R: Read,
    F: Facade,
    I: IntoIterator<Item = char>, 

Creates a new texture representing a font stored in a FontTexture. This function is very expensive as it needs to rasterize font into a texture. Complexity grows as font_size**2 * characters_list.len(). Avoid rasterizing everything at once as it will be slow and end up in out of memory abort.
