Struct freetype::glyph::Glyph

pub struct Glyph { /* fields omitted */ }

Represents a retrieved glyph from the library

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

Methods

impl Glyph

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

Create a freetype-rs glyph object from c constituent parts

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

Transform a glyph image if its format is scalable.

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.

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

Convert a given glyph object to a bitmap glyph object.

fn advance_x(&self) -> isize

fn advance_y(&self) -> isize

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.

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)

Trait Implementations

impl Clone for Glyph

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for Glyph

fn drop(&mut self)

A method called when the value goes out of scope.
