Image Process

Image Process Skill

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

Features

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

compressImage

| Parameter | Type | Description | |-----------|------|-------------| | input | string | Path to input image | | quality | number | Compression quality (1-100), default 80 | | output | string | Output file path |

removeBackground

| Parameter | Type | Description | |-----------|------|-------------| | input | string/Buffer | Path or buffer of input image | | output | string | Output file path (optional) |

replaceBackground

| Parameter | Type | Description | |-----------|------|-------------| | input | string | Path to foreground image | | background | string | Hex color (e.g. '#ffffff') or path to background image | | output | string | Output file path |

upscaleImage

| Parameter | Type | Description | |-----------|------|-------------| | input | string | Path to input image | | scale | number | Scale factor (e.g. 2 for 2x), default 2 | | width | number | Target width (overrides scale) | | height | number | Target height (overrides scale) | | output | string | Output file path |

CLI Commands

Dependencies

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'
});
