Defined in:
lib/ea/svg/ea_emitter/text_renderer.rb

Overview

Single source of truth for emitting <text> SVG elements. Handles:

  • Decimal x/y formatting (%.2f): matches EA's x="11.00" y="19.00" encoding.
  • Always-present rotation transform: even when rotation is 0, EA emits transform="rotate(-0.00 X Y)".
  • Proper XML escaping of content.
  • Optional textLength integer (computed by caller).

Replaces the duplicated build_text helpers across HeaderRenderer, AttributeRenderer, OperationRenderer, EnumerationLiteralRenderer, Labels, and DiagramFrame.
