# pdfminer.six Detailed Layout Analyzer

Inspects low-level PDF visual structures using pdfminer.six: LTTextBox, LTTextLine, LTChar font sizes, and bounding box coordinates to reconstruct complex multi-column reading flows.

## When to Invoke
Invoke this skill whenever you need to:
- extract text boxes pdfminer
- analyze pdf reading order
- extract font size per word pdf

## Execution SOP & Rules
1. Configure LAParams(line_overlap=0.5, char_margin=2.0) to fine-tune grouping heuristics.
2. Iterate over LTPage elements and filter by isinstance(element, LTTextBoxHorizontal).
3. Extract character-level font names and sizes from element.get_text() child characters.
4. Handle unhandled PDF stream decompression exceptions gracefully.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
