Defined in:

Overview

Transforms between FriendlyTheme and WordTheme models.

This transformation is bidirectional:

  • to_word: Themes::Theme → Drawingml::Theme (for document generation)

  • from_word: Drawingml::Theme → Themes::Theme (for extraction/editing)

Architecture:

  • Stateless transformation (no instance state)

  • Follows Transformation pattern from lutaml-model

  • Separates concerns: models own serialization, this class owns conversion

Examples:

Convert friendly theme to Word theme

transformation = ThemeTransformation.new
word_theme = transformation.to_word(friendly_theme)

Extract friendly theme from Word theme

friendly = transformation.from_word(word_theme)

Full roundtrip

word_theme = transformation.to_word(friendly)
extracted = transformation.from_word(word_theme)
friendly.to_yaml == extracted.to_yaml  # => true (semantically)
