Hey, does anyone know how to read a gif/jpg/png image from a Java application. I have a book that explains how to do it with an applet, but I dont want to use an applet. I want it for an application, because applets can't save stuff to the client computer, and applications can be downloaded and can actually save stuff

| Who should know that Applications can use the same classes and methods. |

I guess since an Applet it is a container I could add it to frame and call init(). Im using a ScrollPane for my map though, so I'd have to add it to the Applet and then add the Applet to the Frame. ah, the joys of oop programming.
anyway I dont think you can use the AppletContext methods in an Application. |

I've always used the exact same code with images in Applets and Applications alike.
And JFrame also inherits from container. |

The book I have never explained creating a new Toolkit and using it's methods. It always said to use Applet's getImage() method or Components createImage() method for Applications. However Component's method doesn't allow a String filename argument

It does actually.
[url="http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Toolkit.html#createImage(java.lang.String)"]http://java.sun.com/j2se/1.4.2/docs/api/ja...va.lang.String)[/url] |

look under the API entry for [url="http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Component.html#createImage(java.awt.image.ImageProducer)"]Component.createImage()[/url].
no way to specify a file to read from. The only one of my 5 Java textbooks that explained anything about images whatsoever is mostly for Applets, so it didn't mention toolkit. it mentioned [url="http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Component.html#createImage(java.awt.image.ImageProducer)"]Component.createImage()[/url], and [url="http://java.sun.com/j2se/1.4.2/docs/api/java/applet/Applet.html#getImage(java.net.URL)"]Applet.getImage()[/url].
