CLI

转换

docker run --rm -v ./:/images rayros/respicta convert --help

Convert images from one format to another

Usage: respicta convert [OPTIONS] <INPUT_PATH> <OUTPUT_PATH>

Arguments:
  <INPUT_PATH>   Input image path
  <OUTPUT_PATH>  Output image path

Options:
  -w, --width <WIDTH>      Width of the output image If not set, the width will be the same as the input image
  -h, --height <HEIGHT>    Height of the output image If not set, the height will be the same as the input image
  -q, --quality <QUALITY>  Quality of the output image. If not set, the quality will be the same as the input image. The value must be between 1 and 100. The higher the value, the better the quality
      --help               

Examples: 

respicta convert --width 100 --height 100 --quality 75 input.jpg output.jpg

服务器

docker run --rm rayros/respicta server --help

Start a server to convert images

Usage: respicta server [OPTIONS]

Options:
  -a, --address <ADDRESS>  Address to bind the server (default: 0.0.0.0:3000)
  -l, --limit <LIMIT>      Maximum file size in bytes (default: 10MB)
  -h, --help               Print help

客户端示例

const fs = require('fs');
const { Readable } = require('stream');
const { finished } = require('stream/promises');

const filePath = './images/logo.jpeg';
const url = 'http://0.0.0.0:3000/?width=200&height=200&extension=jpeg';

fs.readFile(filePath, async (err, data) => {
    if (err) {
        console.error('Error reading file:', err);
        return;
    }

    const blob = new Blob([data], { type: 'image/jpeg' });

    const formData = new FormData();
    formData.append('file', blob, 'logo_small.jpeg');

    const response = await fetch(url, {
        method: 'POST',
        body: formData,
    })
    if (!response.ok) {
        const text = await response.text();
        console.error('Error:', text);
        return;
    }
    const fileWriteStream = fs.createWriteStream('./images/logo_small.jpeg');
    await finished(Readable.fromWeb(response.body).pipe(fileWriteStream));
});

命令服务器 - 通过 http 发送 CLI 命令

Start a command server

Usage: respicta command-server [OPTIONS]

Options:
  -a, --address <ADDRESS>  Address to bind the server (default: 0.0.0.0:3000)
  -h, --help               Print help

客户端示例

const run = async () => {
    const response = await fetch('http://0.0.0.0:3000/', {
        method: 'POST',
        body: JSON.stringify({
            input_path: './images/logo.jpeg',
            output_path: './images/logo_small.jpeg',
            width: 200,
            height: 200,
        }),
        headers: {
            'Content-Type': 'application/json',
        }
    })
    if (!response.ok) {
        const text = await response.text();
        console.error('Error:', text);
        return;
    }
};

run().catch(console.error);

Postman 客户端

作为一个库

use respicta::convert;

fn main() {
    convert(&respicta::Config::new(
        "images/logo.jpeg",
        "images/logo_small.jpeg",
        Some(200),
        Some(200),
    ))
    .unwrap();
}
