About this format
CBDT Color Font format context
Format: CBDT Color Font
Overview
CBDT matters because early color-font deployments needed a standard way to embed per-glyph bitmap color images, including PNG-backed emoji-style assets, inside OpenType fonts without abandoning the existing bitmap-strike model.
Font vendors needed a portable table structure for storing color bitmap strikes and locating glyph image data at specific ppem sizes inside standard OpenType files.
CBDT now appears mainly in emoji, legacy color-font compatibility, and small-size bitmap workflows where raster artwork is preferable to outline reconstruction.
CBDT Color Font is closely associated with Google / OpenType specification.
CBDT Color Font is usually selected for workflows that center on type design, brand system deployment, web embedding.
Typical Workflows
- type design
- brand system deployment
- web embedding
Common Software
- OpenType text engines
- emoji fonts
- font editors with bitmap-color support
Strengths
- Supports embedded color bitmap glyphs within ordinary OpenType fonts.
- Allows PNG-based glyph images as well as uncompressed BGRA bitmap data.
- Reuses the familiar strike-and-locator model of older embedded bitmap tables.
Limitations
- Bitmap strikes scale less gracefully than outline-based color font technologies.
- File sizes can grow quickly when many glyphs and sizes are embedded.
Related Formats

Interesting Context
CBDT and its companion CBLC table extended the older EBDT and EBLC bitmap infrastructure into the color-font era, giving OpenType a pragmatic bridge from monochrome embedded bitmaps to multicolor emoji and UI glyphs.
Android emoji font stack and OpenType colour font tooling: Google's fonttools, font build systems, and emoji font authoring workflows.
Stored as OpenType tables within TTF or OTF font files.
Status: active. Introduced: 2013. Invented by: Google. Stewarded by: Google / OpenType specification.
How CBDT Color Font fits into workflows
Workflow role: CBDT Color Font
Convert to CBDT when the font needs bitmap-based color glyphs for emoji, pictograms, or symbol sets that should render consistently on platforms built around the CBLC/CBDT table model.
It is especially useful for Android-oriented emoji pipelines and OpenType font builds that prefer embedded bitmap glyph layers over scalable vector color tables.
