# Image Resizer

A simple Python script for resizing images using `OpenCV`. This tool allows you to resize an image by a specified percentage and save the resized image in a new file.

## Features:

- Resize an image to a custom scale percentage.

- Save the resized image in a specified output file format.

- Preview the resized image in a display window.

## Requirements:

- ### Python 3.x

- ### OpenCV (cv2)

## Installation:

#### Clone this repository to your local machine:

    git clone https://github.com/your-username/Image_Resizer.git

    cd Image_Resizer

#### Install the required OpenCV library if not already installed:

    pip install opencv-python

## Usage:

Place the **source image** (e.g., `srk.jpg`) in the repository folder.

Set the `source`, `destination`, and `scale_percent` variables in the script:

    source = "srk.jpg"        # Path to the original image

    destination = "newSrk.png"  # Path for saving the resized image

    scale_percent = 50         # Resize percentage (e.g., 50% of original size)

#### Run the script:

    python image_resizer.py

The resized image will be saved as `newSrk.png` in the same folder. The script will display the resized image in a preview window. Press any key to close the window.

## Code Overview:

The script follows these steps:

- **Load the Image:** Loads the specified image using `cv2.imread()`.

- **Calculate New Dimensions:**  Calculates the new width and height based on the specified `scale_percent`.

- **Resize the Image:**  Uses `cv2.resize()` to resize the image.

- **Save and Display the Image:**  Saves the resized image using `cv2.imwrite()` and optionally displays it in a new window.

## Example:

For a 50% resize of an image named `srk.jpg`, `set scale_percent = 50`, then run the script. The output file (`newSrk.png`) will be half the size of the original image.

## Potential Enhancements:

- **Command-line Arguments:**  Allow setting parameters like source image, destination file, and scale percentage via command-line options.

- **Aspect Ratio Resize:** Enable resizing by specifying a target width or height while maintaining the original aspect ratio.

- **Batch Processing:**  Resize multiple images at once.
