Struct freetype::glyph::Glyph

source ·
pub struct Glyph { /* private fields */ }
Expand description

Represents a retrieved glyph from the library

Note that when this glyph is dropped, so is the library

Implementations§

source§

impl Glyph

source

pub unsafe fn from_raw(library_raw: FT_Library, raw: FT_Glyph) -> Self

Create a freetype-rs glyph object from c constituent parts

source

pub fn transform( &self, matrix: Option<Matrix>, delta: Option<Vector> ) -> FtResult<()>

Transform a glyph image if its format is scalable.

source

pub fn get_cbox(&self, bbox_mode: FT_Glyph_BBox_Mode) -> BBox

Return a glyph’s ‘control box’. The control box encloses all the outline’s points, including Bézier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline that contains Bézier outside arcs).

Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the ‘ftbbox’ component, which is dedicated to this single task.

source

pub fn to_bitmap( &self, render_mode: RenderMode, origin: Option<Vector> ) -> FtResult<BitmapGlyph>

Convert a given glyph object to a bitmap glyph object.

source

pub fn stroke(&self, stroker: &Stroker) -> FtResult<Glyph>

source

pub fn stroke_border(&self, stroker: &Stroker, inside: bool) -> FtResult<Glyph>

source

pub fn advance_x(&self) -> isize

source

pub fn advance_y(&self) -> isize

source

pub fn format(&self) -> FT_Glyph_Format

An enumeration type used to describe the format of a given glyph image. Note that this version of FreeType only supports two image formats, even though future font drivers will be able to register their own format.

source

pub fn raw(&self) -> &FT_GlyphRec

Get the underlying c glyph struct (The system actually calls this a GlyphRec because it can be a different struct in different circumstances)
