I am try to make things works with tess4j (OCR algorithm), and i m using this code: import java.awt.image.RenderedImage; import java.io.File; import java.net.URL; import javax.imageio.ImageIO; import net.sourceforge.tess4j.*; public static void main(String[] args) throws Exception{ URL imageURL = new URL("http://s4.postimg.org/e75hcme9p/IMG_20130507_190237.jpg"); RenderedImage img = ImageIO.read(imageURL); File outputfile = new File("saved.png"); ImageIO.write(img, "png", outputfile); try { Tesseract instance = Tesseract.getInstance(); // JNA Interface Mapping // Tesseract1 instance = new

I've done several projects and packaged them into jar files, but I've noticed that my jar files run much more slowly than in my IDE. I use Eclipse to compile and run my programs. In Eclipse, I have everything working. When I package my project as a runnable Jar and execute it by double-clicking, everything still works. But when I have animation, the program runs extremely slowly. Instead of 30 frames per second in Eclipse, I now get about 2 frames per second. The animation is very laggy. Interesting thing is, when I run the same Jar from the command prompt ( java -jar MyCode.jar ), the lag

I would like to associate a specific file type with my application, so when I double-click one of the files of this specific type, my application opens. This works just fine, but the file I double-clicked does not get passed as an argument to my program. If I for instance associate my application with txt files and I double-click todo.txt , my application opens, but I have no idea which txt file I double-clicked. From what I can read, this is how it's supposed to work on OS X, and instead of relying on the default behaviour (how it works on e.g. Windows), I should use ApplicationListener
