Overview

Color glyph information model

Represents a complete color glyph from the COLR table, containing multiple layers that are rendered in order to create the final multi-colored glyph.

This model uses lutaml-model for structured serialization to YAML/JSON/XML.

Examples:

Creating a color glyph

glyph = ColorGlyph.new
glyph.glyph_id = 100
glyph.num_layers = 3
glyph.layers = [layer1, layer2, layer3]

Serializing to JSON

json = glyph.to_json
# {
#   "glyph_id": 100,
#   "num_layers": 3,
#   "layers": [...]
# }
