pub enum Font {
    TTFFont {
        font: Font<'static>,
        points: u32,
        scale: Scale,
    },

}

A font that defines the shape of characters drawn on the screen. Can be created from a .ttf file or from an image (bitmap fonts).

Methods

impl Font

fn new<P>(context: &mut Context, path: P, points: u32) -> GameResult<Font> where
    P: AsRef<Path> + Debug, 

Load a new TTF font from the given file.

fn from_bytes(
    name: &str,
    bytes: &[u8],
    points: u32,
    dpi: (f32, f32)
) -> GameResult<Font>

Loads a new TTF font from data copied out of the given buffer.

fn new_bitmap<P: AsRef<Path>>(
    context: &mut Context,
    path: P,
    glyphs: &str
) -> GameResult<Font>

Loads an Image and uses it to create a new bitmap font The Image is a 1D list of glyphs, which maybe isn't super ideal but should be fine. The glyphs string is the characters in the image from left to right.

fn default_font() -> GameResult<Self>

Returns a baked-in default font: currently DejaVuSerif.ttf Note it does create a new Font object with every call.

fn get_height(&self) -> usize

Get the height of the Font in pixels.

The height of the font includes any spacing, it will be the total height a line needs.

fn get_width(&self, text: &str) -> usize

Returns the width a line of text needs, in pixels. Does not handle line-breaks.

fn get_wrap(&self, text: &str, wrap_limit: usize) -> (usize, Vec<String>)

Breaks the given text into lines that will not exceed wrap_limit pixels in length. It accounts for newlines correctly but does not try to break words or handle hypenated words; it just breaks at whitespace. (It also doesn't preserve whitespace.)

Returns a tuple of maximum line width and a Vec of wrapped Strings.

Trait Implementations
