Implementations

impl SimpleGlyph

pub fn from_kurbo(path: &BezPath) -> Result<Self, BadKurbo>

Attempt to create a simple glyph from a kurbo BezPath

The path may contain only line and quadratic bezier segments. The caller is responsible for converting any cubic segments to quadratics before calling.

Returns an error if the input path is malformed; that is, if it is empty, contains cubic segments, or does not begin with a ‘move’ instruction.

Context

• In the glyf table simple (contour based) glyph paths implicitly close when rendering.
• In font sources, and svg, open and closed paths are distinct.
  • In SVG closure matters due to influence on strokes, https://www.w3.org/TR/SVG11/paths.html#PathDataClosePathCommand.
• An explicit closePath joins the first/last points of a contour
  • This is not the same as ending with some other drawing command whose endpoint is the contour startpoint
• In FontTools endPath says I’m done with this subpath, BezPath has no endPath.
