TTF — Colour Font, CBDT/CBLC PNG Strike
A CBDT/CBLC colour font — the embedded-bitmap format Android and Chrome use for colour emoji, here with a 64 ppem 32-bit strike in image format 17. For testing bitmap-strike parsers and the CBDT-versus-sbix branch in a colour-font pipeline. Original typeface, free to use.

Testing contract
Expected to pass- Scenario
- Parse CBLC to find the strike, then decode the CBDT image data for U+E100.
- Expected result
- CBLC reports one 64 ppem strike at bit depth 32 with index format 1; each CBDT record is image format 17, carrying small glyph metrics followed by a decodable PNG.
What is a .ttf file?
TTF (TrueType Font) is a scalable outline font format developed by Apple and Microsoft that uses quadratic Bezier curves and includes hinting for sharp rendering at small sizes. It stores glyph outlines, metrics, and character mappings in a single file. It is one of the most widely supported desktop and web font formats.
How to use this file
Use an example TTF to test font parsers, glyph and metric extraction, text-rendering pipelines, and converters that produce web font formats like WOFF.
How to use this file for testing
“TTF — Colour Font, CBDT/CBLC PNG Strike” is a deterministic Novus Examples fixture for Conversion testing, Metadata testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: seed 20260807 · 32-bit. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Font fixtures carry a small documented glyph set across the common wrappers. Test font loaders, subsetting, and @font-face; the specimen preview renders the glyphs the face actually maps.

- ttcTTC — Collection of Two Variable FontsA collection whose members are themselves variable fonts, each with its own axis, fvar, gvar and STAT. The case that breaks loaders which handle collections or variations but never both at once. Original typeface, free to use.
- ttcTTC — Three-Face Collection with Shared TablesA TrueType Collection holding three faces of one family with identical tables stored once and referenced by offset from each face's table directory. For testing face-index selection, collection-aware loaders, and extractors that must not assume each face owns its tables. Original typeface, free to use.
- ttfTTF — Composite Glyphs (accents built from components)Four precomposed accented letters built the way real fonts build them — as composite glyphs referencing a base letter and a combining mark with a translation. For testing component resolution, nested-glyph handling, and subsetters that must keep a component's base glyph alive. Original typeface, free to use.
- ttfTTF — Correct Checksums (integrity reference)The clean control for the checksum pair: a small, valid font whose head.checkSumAdjustment and every table-directory checksum are correct. Diff it against its damaged twin to see exactly which four bytes a validator is complaining about. Original typeface, free to use.
- ttfTTF — Decomposed Glyphs (identical shapes, no components)The same four accented letters flattened into simple glyphs with the mark contours copied in. Rendering is identical to the composite twin; the file size, the subsetting behaviour and the hinting story are not. Original typeface, free to use.
- ttfTTF — Intentionally Corrupt: Wrong glyf Table-Directory ChecksumAn intentionally corrupt font whose glyf table data is perfectly fine but whose recorded checksum in the table directory is wrong. The complement to the head fixture: this one catches tools that verify per-table checksums, and its glyphs still draw, so the damage is invisible without a real integrity check.
