First step: Put your image in a defined location in your JAR-file. If you put it into the src-folder, maybe your IDE or your build-tool will package it to the JAR automatically. Otherwise check the documentation of your IDE/build-tool, in which location you have to put it. Second step: Access the file from your program.
May 13, 2014 · Make sure the images are within your jar file (e.g. under "/images" in the above example). Also note that you're loading the same image icon in each of your 5 bits of code. I'd strongly recommend loading it once and reusing it.
Sep 15, 2012 · I am using eclipse and I use the following code to load my image from a folder. getClass().getResource("/images/image.jpg").getFile()) The image folder is located inside the bin folder in the project folder. It works fine when loading in eclipse, but when I export it to a jar it does not load.

In this tutorial, we are going to take a look at a few available image-processing libraries, and perform simple image processing operation – loading an image and drawing a shape on it. We’ll try out AWT (and a bit of Swing) library, ImageJ, OpenIMAJ, and TwelveMonkeys.
AWT is a built-in Java library that allows a user to perform simple operations related to display, like creating a window, defining buttons and listeners and so on. It also includes methods that allow a user to edit images. It does not require installation since it is shipped with Java.
ImageJ is a Java-based software created for working with images. It has quite a lot of plugins, available here. We will be using API only, as we want to perform processing by ourselves. It is quite a powerful library, better than Swing and AWT, as it’s creation purpose was image processing and not GUI operations. Plugins contain many free to use al...
OpenIMAJ is set of Java libraries focused not only on computer vision and video processing but also machine learning, audio processing, working with Hadoop and much more. All parts of the OpenIMAJ project can be found here, under “Modules.” We need only the image processing part.
The TwelveMonkeys ImageIO library is intended as an extension to the Java ImageIOAPI, with support for a larger number of formats. Most of the time, the code will look the same as the built-in Java code, but it will function with additional image formats, after adding the necessary dependencies. By default, Java supports only these five formats for...
You have been introduced to 4 libraries that can help you work with images. Going further, you might want to look for some image processing algorithms, like extracting edges, enhancing contrast, using filters or face detection. For those purposes, it might be better to start learning ImageJ or OpenIMAJ. Both are easy to include in a project and are...
Overview. Usually, it’s convenient to bundle many Java class files into a single archive file. In this tutorial, we’re going to cover the ins and outs of working with jar – or Java ARchive – files in Java. Specifically, we’ll take a simple application and explore different ways to package and run it as a jar.
Load the image file from a folder or a jar file: use javax.imageio.ImageIO class to read the image file 16.33.23. Detect the file type of the input stream prior to reading the image
