Struct bmfont::BMFont

pub struct BMFont { /* fields omitted */ }

Holds a decoded bitmap font defintion, including all character advance and kerning values.

Implementations

impl BMFont

pub fn new<R>(
    source: R,
    ordinate_orientation: OrdinateOrientation
) -> Result<BMFont, Error> where
    R: Read, 

Constructs a new BMFont.

Examples

From a file:

let file = std::fs::File::open("font.fnt")?;
let font = BMFont::new(file, OrdinateOrientation::TopToBottom)?;
assert_eq!(font.line_height(), 80);

From a slice of bytes:

let data = std::io::Cursor::new(my_font_bytes);
let font = BMFont::new(data, OrdinateOrientation::TopToBottom)?;
assert_eq!(font.line_height(), 80);

pub fn base_height(&self) -> u32

Returns the height of a EM in pixels.

pub fn line_height(&self) -> u32

pub fn pages(&self) -> PageIter<'_>

Returns an Iterator of font page bitmap filenames.

Examples

let file = std::fs::File::open("font.fnt")?;
let font = BMFont::new(file, OrdinateOrientation::TopToBottom)?;
assert_eq!(font.pages().next(), Some("font.png"));

pub fn parse<'s>(&'s self, s: &'s str) -> Parse<'s>
