Image Editor Project

This Java-based image editor allows users to perform various image manipulation operations such as:

• Viewing pixel values
• Converting an image to grayscale
• Adjusting image brightness
• Transposing (rotating) the image to the left or right
• Inverting the image horizontally or vertically
• Applying a blur effect

The image editor will take an input image file (e.g., sample.jpg) and produce the result in an output image file (output.jpg).

Features

1. View Pixel Values: Prints out the pixel values of the input image.
2. Convert to Grayscale: Converts the input image to grayscale.
3. Increase Brightness: Adjusts the brightness of the input image by a specified percentage.
4. Right Transpose: Rotates the image to the right (90 degrees clockwise).
5. Left Transpose: Rotates the image to the left (90 degrees counter-clockwise).
6. Invert Horizontally: Flips the image along the horizontal axis.
7. Invert Vertically: Flips the image along the vertical axis.
8. Blur Image: Applies a blur effect to the input image based on pixel grouping.

Prerequisites

• Java Development Kit (JDK) installed.
• javax.imageio.ImageIO library (part of the standard JDK) is required for image reading/writing.
• An image file named sample.jpg or any other image file you'd like to manipulate.

How to Run the Program

1. Clone the Project

   • Clone the repository or download the source code.

2. Compile the Code

   • Open a terminal in the project directory.
   • Compile the program using the following command:

     javac imageeditor.java

3. Run the Program

   • After compiling, run the program with the command:

     java imageeditor

4. Provide Input

   • Enter the filename of the image you'd like to manipulate (e.g., sample.jpg).
   • You will be prompted to select one of the following options:

     Enter 1 for Pixel value
     Enter 2 for Convert IMAGE GRAY
     Enter 3 for Increase IMAGE BRIGHTNESS
     Enter 4 for Right Transpose Image
     Enter 5 for Left Transpose Image
     Enter 6 for Invert Horizontal Image
     Enter 7 for Invert Vertical Image
     Enter 8 for Blur Image
     

5. Save the Output

   • Depending on the option selected, the manipulated image will be saved as output.jpg in the project directory.

Example Usage

• To convert the image to grayscale:

3

Output

The manipulated image will be shown in output.jpg in the same directory.
