Refactor: _collect_figure_metadata.py (3384 lines → <512)

[ywatanabe1989]

Parent: #95

File

src/scitex/plt/utils/_collect_figure_metadata.py

Current: 3384 lines | Target: <512 lines

Suggested Approach

• Split metadata collectors by type (axes, legends, annotations)
• Create submodule structure for different matplotlib elements
• Extract helper functions into separate utilities

[ywatanabe1989]

This file is part of scitex.plt.utils which is scheduled for migration to figrecipe per #124 (Phase 4). Rather than refactoring in place, this will be addressed as part of the plt→figrecipe migration effort.
