Struct Font 

pub struct Font<'a> { /* private fields */ }

The font as the one-bit renderer reads it: the glyph map and the one-bit atlas the game gives.

Implementations

impl<'a> Font<'a>

pub fn new( atlas: &'a FontAtlasDef, bits: &'a [u8], ) -> Result<Self, &'static str>

The font of glyph map atlas and one-bit atlas bits. Fails if a cell is wider than 8 pixels or bits lacks a glyph of the map.

pub fn rows(&self, glyph: char) -> Option<&'a [u8]>

The pixel rows of glyph (a set bit is a pixel of the glyph), or of the fallback glyph if the font lacks it.

pub fn cell_rows(&self, buf: &GlyphBuffer, x: i32, y: i32) -> Option<&'a [u8]>

The pixel rows drawn in cell (x, y) of buf: its glyph’s (rows), or a half of a wide glyph’s, the left in its first cell and the right in its continuation. None for a space, and for a continuation whose glyph the font has no wide glyph for.
