Third-Party Components Included in ServBay ​

ServBay comes with several third-party components out of the box, covering a wide range of fields from image processing to network communication, compression and decompression, encryption and security, etc. This document will detail these components and their basic usage.

Table of Contents ​

Image Processing Components ​

ImageMagick ​

ImageMagick is a powerful image processing toolkit and library that supports various image formats. It provides functions to create, edit, and compose images.

Basic Usage ​

  • Convert image formats

    bash
    magick convert input.jpg output.png

  • Resize images

    bash
    magick convert input.jpg -resize 300x300 output.jpg

  • Add watermark

    bash
    magick convert input.jpg -gravity southeast -draw "text 10,10 'ServBay'" output.jpg

cwebp ​

cwebp is a command line tool for converting images to the WebP format. WebP is a modern image format that offers better compression and quality.

Basic Usage ​

  • Convert JPEG to WebP format

    bash
    cwebp input.jpg -o output.webp

  • Convert PNG to WebP format

    bash
    cwebp input.png -o output.webp

  • Set compression quality

    bash
    cwebp -q 80 input.jpg -o output.webp

jpegtran ​

jpegtran is a lossless JPEG transformation tool used to rotate, flip, and transpose JPEG images.

Basic Usage ​

  • Rotate JPEG image

    bash
    jpegtran -rotate 90 input.jpg > output.jpg

  • Horizontally flip JPEG image

    bash
    jpegtran -flip horizontal input.jpg > output.jpg

djpeg ​

djpeg is a tool for decompressing JPEG files into PPM, PGM, BMP, or Targa formats.

Basic Usage ​

  • Decompress JPEG to PPM format
    bash
    djpeg input.jpg > output.ppm

cjpeg ​

cjpeg is a tool for compressing PPM, PGM, BMP, or Targa format images into JPEG files.

Basic Usage ​

  • Compress PPM to JPEG format
    bash
    cjpeg input.ppm > output.jpg

img2webp ​

img2webp is a tool for combining multiple images into a single WebP file, often used to create animated WebP images.

Basic Usage ​

  • Combine multiple images into an animated WebP
    bash
    img2webp -o output.webp frame1.png frame2.png frame3.png

Network Communication Components ​

cURL ​

cURL is a command line tool and library for transferring data. It supports various protocols including HTTP, HTTPS, FTP, etc.

Basic Usage ​

  • Send HTTP GET request

    bash
    curl -X GET https://api.example.com/data

  • Send HTTP POST request

    bash
    curl -X POST -d "param1=value1&param2=value2" https://api.example.com/data

  • Download file

    bash
    curl -O https://example.com/file.zip

Compression and Decompression Components ​

bzip2 ​

bzip2 is an efficient compression tool that typically produces smaller files than gzip.

Basic Usage ​

  • Compress file

    bash
    bzip2 input.txt

  • Decompress file

    bash
    bunzip2 input.txt.bz2

gzip ​

gzip is a widely used compression tool, especially in Unix and Linux systems.

Basic Usage ​

  • Compress file

    bash
    gzip input.txt

  • Decompress file

    bash
    gunzip input.txt.gz

xz ​

xz is an efficient compression tool that uses the LZMA2 algorithm.

Basic Usage ​

  • Compress file

    bash
    xz input.txt

  • Decompress file

    bash
    unxz input.txt.xz

zstd ​

zstd is a fast compression algorithm providing high compression ratios and fast decompression speeds.

Basic Usage ​

  • Compress file

    bash
    zstd input.txt

  • Decompress file

    bash
    unzstd input.txt.zst

Encryption and Security Components ​

OpenSSL ​

OpenSSL is a powerful open-source toolkit for implementing secure communication. It provides functions for encryption, decryption, SSL/TLS protocols, and more.

Basic Usage ​

  • Generate RSA private key

    bash
    openssl genpkey -algorithm RSA -out private_key.pem

  • Generate public key from private key

    bash
    openssl rsa -pubout -in private_key.pem -out public_key.pem

  • Generate self-signed certificate

    bash
    openssl req -x509 -days 365 -key private_key.pem -in request.csr -out certificate.crt

Conclusion ​

ServBay includes several powerful third-party components, covering a wide range of fields from image processing to network communication, compression and decompression, encryption, and security. Through this document, you can understand how to use these tools for various tasks.
