Usage

1. Compress Image

const { compressImage } = require('./index');

const result = await compressImage({
  input: './image.jpg',
  quality: 80,
  output: './compressed.jpg'
});

2. Remove Background

const { removeBackground } = require('./index');

const result = await removeBackground({
  input: './person.jpg',
  output: './person-nobg.png'
});

3. Replace Background

const { replaceBackground } = require('./index');

// Replace with solid color
const result = await replaceBackground({
  input: './person.jpg',
  background: '#ffffff',
  output: './result.jpg'
});

// Replace with another image
const result = await replaceBackground({
  input: './person.jpg',
  background: './background.jpg',
  output: './result.jpg'
});

4. Upscale Image

const { upscaleImage } = require('./index');

// Scale by factor (2x)
const result = await upscaleImage({
  input: './image.jpg',
  scale: 2,
  output: './upscaled.jpg'
});

// Or specify exact dimensions
const result = await upscaleImage({
  input: './image.jpg',
  width: 2000,
  height: 3000,
  output: './upscaled.jpg'
});

这个图片处理 Skill 功能覆盖较全面，中英文文档清晰易懂，使用主流图片处理库。对于常见的图片压缩、背景处理、放大需求都能较好满足。主要问题是缺少测试保障，文档部分内容不够通用。对于一般使用场景来说质量可用，但细节打磨还有提升空间。
