Image Temperature Adjustment Script

Overview

This script is designed to adjust the color temperature of JPEG images, simulating warmer or cooler tones. The primary purpose is to provide a tool for modifying the color tones of images while preserving overall image quality.

Features

• Temperature Adjustment: The script accepts a temperature adjustment value (positive for warmer, negative for cooler) and applies it to the input image.

• JPEG Format: The script specifically handles JPEG image files for both input and output.

• Input Validation: Input parameters, including file paths and temperature adjustment values, are validated to ensure the script operates correctly.

Requirements

• Node.js: Ensure that Node.js is installed on your system. You can download it from Node.js Downloads.

• Dependencies: Install the necessary dependencies using the following command:

  npm install sharp

Usage

Run the script from the command line using the following syntax:

npm start -- input_image.jpg output_image.jpg temperature_adjustment_value

• input_image.jpg: Path to the input JPEG image.
• output_image.jpg: Path to save the adjusted JPEG image.
• temperature_adjustment_value: Numeric value for temperature adjustment (positive for warmer, negative for cooler).

Example

Adjust the temperature of an image to make it warmer:

npm start -- input_image.jpg output_image.jpg 10

Adjust the temperature of an image to make it cooler:

npm start -- input_image.jpg output_image.jpg -10
