Description

Map wkhtmltopdf page/layout flags to Chrome --print-to-pdf arguments.

Tasks

  • Map --page-size to Chrome paper sizes:
    • A4, Letter, Legal, Tabloid, A3, A5, B4, B5
  • Map --page-width + --page-height to custom dimensions (mm → inches)
  • Map --orientation to landscape/portrait
  • Map margins (--margin-top, --margin-bottom, --margin-left, --margin-right) from mm to inches
  • Conversion: inches = mm / 25.4
  • Build Chrome --print-to-pdf argument string with all mapped values

Acceptance Criteria

  • --page-size A4 → --print-to-pdf=paperSize=A4
  • --orientation landscape → --print-to-pdf=landscape=true
  • --margin-top 20 → top margin = 0.787 inches in Chrome args
  • --page-width 210 --page-height 297 → custom paper size in inches
  • Combined flags produce correct composite Chrome argument string

Notes

  • Chrome --print-to-pdf accepts key=value pairs
  • Relates to PRD #2
