convert input.png -threshold 50% temp.pbm
potrace temp.pbm -s -o output.svg
rm temp.pbm

#!/bin/bash
for file in *.png; do
  base=$(basename "$file" .png)
  convert "$file" -threshold 50% "${base}.pbm"
  potrace "${base}.pbm" -s -o "${base}.svg"
  rm "${base}.pbm"
  echo "Converted: $file -> ${base}.svg"
done

Chapter 5: Quality Optimization Strategies

Pre-Conversion Optimization

• Resolution Sweet Spot: 300-800px width provides optimal tracing accuracy
• Contrast Enhancement: Increase contrast by 15-25% before conversion
• Edge Sharpening: Apply subtle sharpening to define boundaries
• Background Removal: Use transparent backgrounds for cleaner paths

• Color Palette Reduction: Limit to 8-16 colors for simpler SVG output
• Posterization: Apply slight posterization to reduce gradient complexity
• Dithering Removal: Eliminate dithering patterns that create unnecessary paths

Post-Conversion Refinement

• Node Reduction: Remove unnecessary anchor points (target: 30-50% reduction)
• Curve Smoothing: Convert sharp corners to smooth curves where appropriate
• Path Merging: Combine overlapping or adjacent paths

<!-- Before optimization -->
<path d="M10.5,20.3L11.2,20.8L12.1,21.2L13.3,21.5" fill="#FF0000"/>

<!-- After optimization -->
<path d="M10.5,20.3C11.2,20.8,12.1,21.2,13.3,21.5" fill="red"/>

• File Size Target: Aim for 70-90% reduction from original PNG
• Render Speed: Test loading performance in target browsers
• Scaling Quality: Verify appearance at 0.5x to 10x scale

Chapter 6: Industry-Specific Applications

Web Development and UX Design

• Workflow: Batch convert using SVG Converter
• Optimization: Maintain 24px base size for optimal rendering
• Implementation: Use CSS classes for consistent sizing

Print and Branding

• Performance Benefits: 60% smaller app bundle sizes
• Scalability: Perfect rendering across device densities

Chapter 7: Advanced Techniques and Automation

Batch Processing Workflows

1. Categorize Images: Sort by complexity (simple, medium, complex)
2. Template Settings: Create conversion presets for each category
3. Quality Assurance: Implement automated validation checks
4. Version Control: Maintain both PNG and SVG versions

// Node.js batch conversion with quality validation
const fs = require('fs');
const { execSync } = require('child_process');

const convertBatch = (inputDir, outputDir) => {
  const files = fs.readdirSync(inputDir).filter(f => f.endsWith('.png'));
  
  files.forEach(file => {
    const input = inputDir + '/' + file;
    const output = outputDir + '/' + file.replace('.png', '.svg');
    
    // Convert using your preferred tool
    execSync('your-converter "' + input + '" "' + output + '"');
    
    // Validate output quality
    if (validateSVG(output)) {
      console.log('✓ Successfully converted: ' + file);
    } else {
      console.error('✗ Quality check failed: ' + file);
    }
  });
};
