Struct GlyphFont 

pub struct GlyphFont { /* private fields */ }

A loaded font that blits glyphs directly to a u32 framebuffer.

Implementations

impl GlyphFont

pub fn from_bytes(data: &[u8]) -> Result<Self, String>

Load from raw TTF/OTF bytes.

pub fn from_path(path: &str) -> Result<Self, String>

Load from a file path.

pub fn measure(&mut self, text: &str, px: f32) -> f32

Total advance width of text at size px, in pixels.

pub fn draw_text( &mut self, buf: &mut [u32], w: usize, h: usize, x: f32, y: f32, px: f32, color: u32, text: &str, )

Draw text into a packed 0x00RRGGBB framebuffer of w×h pixels.

(x, y) is the top-left of the text box (matching the vector ui_text convention): the baseline is placed px below y via the font’s ascent. Each glyph’s coverage alpha-blends color over the existing pixels.
