After discovering Clojure, reading everything I could about it, and loving everything I saw, the next logical step was to start playing with it.
Being a complete Java novice, I have absolutely no experience with its libraries and was hoping to become more acquainted with them. One of the first things I've tried to do is create a simple Swing app that loads and displays an image, based mostly on the code here: http://java.sun.com/docs/books/tutorial/2d/basic2d/examples/WeatherWizard.java I have a fairly simple question as well as a problem that have arisen from my attempts. In trying to create a basic image loading function based on this: private BufferedImage loadImage(String name) { String imgFileName = "images/weather-"+name+".png"; URL url = WeatherWizard.class.getResource(imgFileName); BufferedImage img = null; try { img = ImageIO.read(url); } catch (Exception e) { } return img; } I've come up with the following function (which obviously has no exception handling and unlike the original takes a full filename as an argument): (defn load-image [name] #^BufferedImage (. ImageIO (read (new File name)))) Firstly: is this an acceptable/possible/necessary use of type hints? Would this be equivalent? (defn #^BufferedImage load-image [name] (. ImageIO (read (new File name)))) Or this: (def #^BufferedImage load-image (fn [name] (. ImageIO (read (new File name))))) Secondly, and seemingly unrelated to the type hint: This function does not work. I get a "java.lang.Exception: Unable to resolve symbol: ImageIO in this context." This has been frustrating me, since it seems like such a trivial function to be porting. Is this simply my not understanding some part of the underlying libraries, or am I so dense that I'm not grasping some basic Clojure syntax? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
