Struct TextPipeline 

pub struct TextPipeline { /* private fields */ }

End-to-end text shaping + rasterization pipeline for OxiUI.

Wraps oxitext::Pipeline and maps errors to TextError / UiError.

Implementations

impl TextPipeline

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

Create a new pipeline from raw font bytes (TTF or OTF).

Errors

Returns TextError::Pipeline if the font bytes are invalid or unparseable.

pub fn from_system_font(family: &str) -> Result<Self, TextError>

Create a pipeline using a named system font family.

Errors

Returns TextError::Pipeline if no matching system font is found.

pub fn set_fallback_fonts(&mut self, fonts: Vec<Vec<u8>>)

Configure a font fallback chain.

When a glyph is .notdef in the primary font the pipeline walks this list to find a substitute.

pub fn shape( &mut self, text: &str, style: &TextStyle, ) -> Result<ShapedText, TextError>

Shape and lay out text under style, returning per-line glyph positions without rasterizing.

Errors

Propagates shaping/layout errors.

pub fn measure( &mut self, text: &str, style: &TextStyle, ) -> Result<(f32, f32), TextError>

Measure total bounding box without rasterizing.

Returns (width, height) in pixels.

Errors

Propagates shaping/layout errors.

pub fn glyph_positions( &mut self, text: &str, style: &TextStyle, ) -> Result<Vec<GlyphPosition>, TextError>

Return per-glyph positions for hit-testing.

Errors

Propagates shaping/layout errors.

pub fn render( &mut self, text: &str, style: &TextStyle, ) -> Result<RenderResult, UiError>

Shape and rasterize text with the given style.

Returns a RenderResult containing per-glyph bitmaps.

Errors

Propagates pipeline errors as UiError::Render.
