orinium_browser::platform::renderer::text_measurer

Struct PlatformTextMeasurer

pub struct PlatformTextMeasurer { /* private fields */ }

Expand description

Platform-backed text measurer using glyphon / cosmic-text.

This measurer performs real text shaping and line layout, and is intended for production use.

Implementations§

Source §

impl PlatformTextMeasurer

Source

pub fn new() -> Result<Self, Box<dyn Error>>

Initialize using system fonts.

TODO:

Share font system with PlatformTextRenderer
Support font family / fallback selection

Source

pub fn from_bytes(_id: &str, bytes: Vec<u8>) -> Result<Self, Box<dyn Error>>

Initialize from raw font bytes.

Trait Implementations§

Source §

impl TextMeasurer<TextStyle> for PlatformTextMeasurer

Source §

fn measure( &self, req: &TextMeasureRequest<TextStyle>, ) -> Result<TextMetrics, TextMeasureError>

Measure text using real shaping and line layout.

Notes:

Baseline is currently approximated
Decorations and alignment are handled at render time
