📦 Image Process — 技能工具

This skill provides image processing capabilities including compression, background removal, background replacement, and upscaling.

Features

• Image Compression: Compress images to reduce file size with adjustable quality
• Background Removal: AI-powered background removal using @imgly/background-removal
• Background Replacement: Replace background with a custom color or another image
• Image Upscaling: Enlarge images to bigger dimensions

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'
});

Parameters
