Configuration Types

PageLayoutConfig

Controls page margins and paragraph spacing.

interface PageLayoutConfig {
  margins?: PageMargins;
  paragraphSpacing?: ParagraphSpacingConfig;
}

Example:

pageLayout: {
  margins: {
    top: { unit: 'INCHES', value: 1.0 },
    bottom: { unit: 'INCHES', value: 1.0 },
    left: { unit: 'INCHES', value: 0.75 },
    right: { unit: 'INCHES', value: 0.75 }
  },
  paragraphSpacing: {
    before: { unit: 'PTS', value: 12 },
    after: { unit: 'PTS', value: 12 }
  }
}

PageMargins

Defines page margins with unit support.

interface PageMargins {
  top: MarginConfig;
  bottom: MarginConfig;
  left: MarginConfig;
  right: MarginConfig;
}

interface MarginConfig {
  unit: 'CM' | 'INCHES';
  value: number;
}

Supported Units:

• 'CM': Centimeters
• 'INCHES': Inches

ParagraphSpacingConfig

Controls spacing between paragraphs.

interface ParagraphSpacingConfig {
  before: {
    unit: 'PTS';
    value: number;
  };
  after: {
    unit: 'PTS';
    value: number;
  };
}

Supported Units:

• 'PTS': Points (1 point = 1/72 inch)

PageNumberConfig

Configures page numbering display and positioning.

interface PageNumberConfig {
  show: boolean;                    // Enable/disable page numbers
  showCount: boolean;              // Show total page count (e.g., "1 of 5")
  showOnFirstPage: boolean;        // Show page number on first page
  position: 'top' | 'bottom' | null;  // Vertical position
  alignment: 'left' | 'center' | 'right' | null;  // Horizontal alignment
}

Example:

pageNumber: {
  show: true,
  showCount: true,
  showOnFirstPage: false,
  position: 'bottom',
  alignment: 'center'
}

Utility Classes

UnitConversion

Utility class for converting between different measurement units.

import { UnitConversion } from '@adalat-ai/page-extension';

const converter = new UnitConversion();

// Convert pixels to millimeters
const mm = converter.pxConversionMm(96); // 25mm

// Convert millimeters to pixels
const px = converter.mmConversionPx(25); // 96px

// Convert points to pixels
const ptToPx = converter.ptConversionPx(12); // 16px

// Convert pixels to points
const pxToPt = converter.pxConversionPt(16); // 12pt

Methods:

• pxConversionMm(value: number): number - Convert pixels to millimeters
• mmConversionPx(value: number): number - Convert millimeters to pixels
• ptConversionPx(value: number): number - Convert points to pixels
• pxConversionPt(value: number): number - Convert pixels to points

🎨 Styling

The extension automatically injects all necessary CSS styles. Your content will automatically have:

• 📏 A4 page dimensions with proper scaling
• 🎭 Professional shadows and borders
• 📐 Proper margins and spacing
• 📱 Responsive design for different screen sizes
• ✍️ Typography optimized for documents

Custom Styling

You can override default styles by targeting the generated CSS classes:

/* Custom page styling */
.Page {
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
  border: 1px solid #e0e0e0;
}

/* Custom page content styling */
.PageContent {
  padding: 20px;
  line-height: 1.6;
}

/* Custom page number styling */
.PageNumber {
  font-size: 12px;
  color: #666;
}

🆘 Troubleshooting

Common Issues

Page dimensions not working

// Ensure you provide valid numeric values
PageExtension.configure({
  bodyHeight: 1123, // Must be a positive number (A4 height at 96 DPI)
  bodyWidth: 794,   // Must be a positive number (A4 width at 96 DPI)
})

Page numbers not showing

// Check your page number configuration
pageNumber: {
  show: true,        // Must be true
  position: 'bottom', // Must be 'top' or 'bottom'
  alignment: 'center' // Must be 'left', 'center', or 'right'
}

Content not paginating

// Ensure PageDocument is included
extensions: [
  PageDocument, // Required
  PageExtension.configure({...}),
  // ... other extensions
]

Styling issues

// The extension auto-injects styles, but you can override them
// Check browser console for any CSS conflicts

Performance Tips

1. Use appropriate page dimensions for your content
2. Limit paragraph spacing for better performance
3. Avoid extremely large documents without pagination
4. Use the recompute command sparingly
5. Monitor memory usage with large documents
