Overview

SVG glyph representation model

Represents an SVG document for a glyph or range of glyphs from the SVG table. Each SVG document can cover multiple glyph IDs and may be compressed.

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

Examples:

Creating an SVG glyph

svg_glyph = SvgGlyph.new
svg_glyph.glyph_id = 100
svg_glyph.start_glyph_id = 100
svg_glyph.end_glyph_id = 105
svg_glyph.svg_content = '<svg>...</svg>'
svg_glyph.compressed = false

Serializing to JSON

json = svg_glyph.to_json
# {
#   "glyph_id": 100,
#   "start_glyph_id": 100,
#   "end_glyph_id": 105,
#   "svg_content": "<svg>...</svg>",
#   "compressed": false
# }
