Image to rounded corner image java project using swing classes in netbeans

By Pawan kumar

The objective of this project is to transform a basic image into one featuring rounded corners. To create the user interface components, we make use of the Swing GUI library.

Before utilizing this packet, it's essential to consider the following key points:

1. To commence your development journey, ensure that your environment is correctly configured. This includes the installation and setup of NetBeans, complete with the necessary Java Development Kit (JDK) and libraries.

2. When working with Swing for GUI and standard Java libraries for image processing, external libraries may not be required.

3. Proficiency in developing graphical user interfaces (GUIs) using Swing, which involves incorporating elements like buttons, is assumed.

4. A fundamental understanding of image processing concepts and familiarity with Java's built-in classes for image management, such as BufferedImage, is important.

5. Familiarity with the Graphics2D class is vital when dealing with images.

6. If you are not already adept in Java Swing, acquiring familiarity with it is crucial, as you will be tasked with creating a user interface using Swing components.

To initiate the project, follow these steps:

1. Open NetBeans and create a new project named 'RoundedCornerImage.' Inside the project, create a class also named 'RoundedCornerImage.' Import the image you wish to transform into a rounded corner image.

2. Create a function named 'RoundedCornerImage().' This function will be called from the main function. Start by using the 'loadImage' method to input the image, which employs 'getResourceAsStream()' to retrieve it.

3. To create a rounded image, provide the input image and specify the desired border-radius. This can be accomplished by calling the 'createRoundedImage()' method. This method generates a new BufferedImage with rounded corners using a Graphics2D object to manipulate the image. It defines a clipping region with a RoundRectangle2D shape to round the corners and then draws the original image onto the new image using the 'drawImage' method provided by Graphics2D.

4. Generate a rounded corner image using an image icon and add it to a JLabel. Display the resulting transformed image with rounded corners in a user-friendly interface.

5. Implement an ActionListener to add a close button to the rounded image, enabling its removal from the screen. This ActionListener executes the 'dispose()' function.

The image below illustrates the resulting rounded corner image with the close button for reference.
