ImageMagick Java Integration Examples

The example projects demonstrate ImageMagick and Java integration with IM4java and JMagick.

Project Name	Description
im4javademo	Im4java Java Examples
im4javademo-kotin	IM4java Kotlin Examples
jmagickdemo	JMagick Java Examples

There is a wired issue I found using IM4java in a Kotlin project, check the original post on StackOverflow.

Prerequisites

All these projects used Gradle as a building tool and tested against Java 21 on Ubuntu 24.04.

Due to both IM4Java and JMagicks depending on ImageMagick, before running the projects, you have to install openjdk-21-jdk, imagemagick, libjmagick6-jni packages.

sudo apt install openjdk-21-jdk imagemagick libjmagick-jni

Build

1. Check out the source codes.
2. Add a test-purpose JPEG image to the project root folder, and rename it to test.jpg.
3. Open a terminal, switch to the project root folder, run ./gradlew clean :app:run.

On Windows, you can install WSL/Ubuntu as the development environment, and use VSCode as the code editor.

• Enable Hyper-V virtual manager in the Windows components.
• Install WSL and Ubuntu from the Microsoft Store or winget command line.
• Start Ubuntu from the start menu and initialize the Ubuntu system. Follow the above guide to install the required packages in Ubuntu.
• Install VSCode with Java Extension Pack and Remote Development Extension Pack.
• Open a terminal, such as PowerShell, and connect WSL/Ubuntu via the command code --remote wsl+Ubuntu /home/yourname/projects.
