Images often serve as powerful communicators, conveying information in a visual language. Adding annotations to images can significantly enhance their value and usability. In this tutorial, we will explore the process of how to add highlight annotation to JPG using Java, providing you with a comprehensive guide to seamlessly integrate this functionality into your projects. Following steps and code example shows how to make highlight annotation in Java for JPG.
Steps to Add Highlight Annotation to JPG using Java
- Configure your Integrated Development Environment (IDE) to utilize GroupDocs.Annotation for Java, enabling the integration of a highlight annotation into a JPG image
- Create an instance of the Annotator class by providing the JPG file path as a parameter to its constructor
- Instantiate the HighlightAnnotation class and define the necessary properties, such as BackgroundColor, Opacity, and position
- Call the Annotator.add method, passing the HighlightAnnotation object as an argument
- Call the Annotator.save method to save the resulting JPG output to the disk
By following these steps, you can seamlessly insert highlight annotation in JPG using Java. As you explore the idea of highlighting text in images, remember that this approach makes things easier and ensures that it works well on different types of computers. It’s a useful tool for developers who want to enhance how they handle images. These steps work on popular systems like Windows, macOS, and Linux, all of which support Java. You don’t need to install any extra software to add highlighted notes to a JPG file.
