Type Light is a streamlined, lightweight freeware font editor by Ten by Twenty that allows you to design, edit, and convert custom TrueType and OpenType (.otf) fonts. It offers an uncluttered user interface ideal for beginners and independent type designers who want to build functional Western Latin fonts from scratch without the steep learning curve of enterprise software. Phase 1: Setting Up Your New Font
When initializing a project, Type Light sets up the basic metadata and default glyph placeholders required for operating systems to register the font file. Initialize the File: Open Type Light, go to File > New.
Define Family Metadata: Input your Family Name (e.g., “MyCustomSans”) and Sub family (e.g., “Regular”).
Configure Full Name: Combine them in the Full Name field (e.g., “MyCustomSans Regular”).
Copyright & Credits: Fill in your personal copyright info in the respective box.
Understand System Glyphs: The software automatically creates the first four core system glyphs.
Glyph 0 represents the undefined character (the missing-character box symbol). Glyphs 1 and 2 are mapped to background control characters.
Glyph 3 is mapped to the space character—leave it empty, but change its width parameter to establish word spacing. Phase 2: Drawing and Mapping Glyphs
The mapping window serves as your workspace canvas, correlating drawn vector shapes to specific keyboard keystrokes.
Create a Glyph Slot: Press the New Glyph button to open a fresh character window.
Assign Character Mapping: Link the slot to a standard unicode value (such as Western Latin 1252 codepage) so typing a key outputs your character.
Manipulate Bézier Curves: Use the primary point tools in the left-hand toolbox to draw your letterforms using vector nodes.
Establish Font Metrics: Define structural boundaries for your letters. Baseline: The invisible line where characters rest.
Side Bearings: The blank spaces to the left and right of your vector art which dictate default letter spacing. Phase 3: Technical Constraints and Guidelines
To prevent font errors, text clipping, or performance crashes across software platforms, your design elements must adhere to strict technical guidelines.
Node Economy: Keep individual glyph vector totals under 1,000 anchor points to prevent rendering and file saving failures.
Contour Directions: Ensure your vector paths follow correct orientation rules. External outlines must run clockwise, while inner cutouts (counters, like the hole inside an ‘O’) must run counter-clockwise.
Vertical Metrics: Set your typographic ascender minus the descender to equal a clean unit square (typically 1,000 units) to avoid strange line heights. Phase 4: Exporting and Testing Your Font
Once your glyph library is built, the final stage is deployment and validation. How do I use an OpenType font with my LaTeX document? – TeX
