This crate provides a high level interface for reading font metadata. It is built on top of the [read-fonts] low level parsing library.

This is still in very early stages and not yet ready for use.

Features

The first cut of the library intends to expose the following metadata:

• Variation axes and named instances
  • Conversion to normalized coordinates
• Global font metrics with variation support (units per em, ascender, descender, etc)
• Glyph metrics with variation support (advance width, left side-bearing, etc)
• Codepoint to nominal glyph identifier mapping
  • Unicode variation selectors

Future goals include:

• Localized strings
• Layout feature enumeration
  • Coverage (is a particular glyph processed by a feature?)
• Color palettes
• Bitmap strikes

Non-goals

This library is not intended to support glyph scaling (loading and hinting of outlines) or shaping (processing of subsitution and positioning features).
