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({

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

// 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,

這個圖片處理 Skill 功能覆蓋較全面，中英文文件清晰易懂，使用主流圖片處理庫。對於常見的圖片壓縮、背景處理、放大需求都能較好滿足。主要問題是缺少測試保障，文件部分內容不夠通用。對於一般使用場景來說質量可用，但細節打磨還有提升空間。
