pdflib-impl-page-layout

What problem does it solve?

Prevents the most common pdf-lib layout mistakes by teaching top-down positioning for a bottom-left coordinate system, enforcing margins, and detecting page overflow so content does not appear in the wrong place or get clipped.

Core Features & Use Cases

• Coordinate awareness: Clear guidance for working with pdf-lib's bottom-left origin to avoid inverted Y-axis errors when placing text, images, and shapes.
• Margin and content area management: Patterns for defining content regions, header/footer placement, and consistent spacing across pages.
• Flow and pagination: CursorY pattern, overflow checks, and page-break logic to render multi-page documents, multi-column layouts, tables, and captioned images reliably.
• Measurement-first approach: Emphasizes measuring text and image dimensions to center elements and estimate wrapped text height before advancing the cursor.
