Image Processing using STB Image Library

This repository contains a simple C program for image processing using the STB Image library. The program loads an image, performs pixel manipulation, and saves the result as a new image.

Getting Started

Prerequisites

• STB Image Library (already included in the repository)

Installation

1. Clone the repository:

   git clone https://github.com/SaranDharshanSP/Image-Processing-Negative-Image-in-C.git
   cd your-repo

2. Compile the program:

   gcc -o Image-Processing-Negative-Image-in-C image_processing.c -lm

Usage

1. Make sure you have an image named amm.jpg in the same directory as the executable.

2. Run the compiled program:

   ./image_processing

   The program will process the image, create a new image named nan.jpg, and save it in the same directory.

Example

Input Image	Output Image
Input Image 1	Output Image 1
Input Image 2	Output Image 2
Input Image 3	Output Image 3
Input Image 4	Output Image 4
Input Image 5	Output Image 5
Input Image 6	Output Image 6

Description

This program demonstrates basic image processing using the STB Image library. The following steps are performed:

1. Load an image named amm.jpg.
2. Determine the image's width, height, and number of color channels.
3. Allocate memory for a new image (nimg) to store the manipulated pixels.
4. Depending on the number of channels, invert pixel values:
   • For grayscale images (1 or 2 channels), invert pixel values.
   • For RGB images (3 channels), invert each channel's pixel value.
5. Save the manipulated image as nan.jpg.
