Handle Complex Files

Core Fixes

  • JSON Parsing: Leading zeros (004 → 4.0) handled with ALLOW_NUMERIC_LEADING_ZEROS
  • Separated Dimensions: Position with s: true reads from x/y fields
  • Transform Order: Correct order: position → rotation → scale → anchor
  • Color Clamping: Values > 1.0 normalized to 0.0-1.0 range
  • Null-Safe Properties: Defaults for width, height, inPoint, outPoint, fps

Advanced Features

  • Trim Paths: Animated arcs for loading spinners
  • Stroke Line Caps: Butt, round, square
  • Stroke Line Joins: Miter, round, bevel
  • Layer Parenting: Hierarchical transforms (parent-child relationships)
  • NULL Layer Handling: Type 3 layers skip rendering but apply transforms

What Now Works

  • test_circle.json: Correctly positioned
  • loading.json: Animated spinner with trim paths
  • timeline.json: Complex animation with parenting, shapes move together correctly
  • All basic shapes render with proper styling
