Here is a way to save BufferedImage as JEPG using ImageWriter. public static void writeAsJpeg(BufferedImage image, float quality, File outputFile) throws IOException { ImageWriter writer = getImageWriter("jpg"); JPEGImageWriteParam iwp = new JPEGImageWriteParam(Locale.getDefault()); iwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); iwp.setCompressionQuality(quality); try (ImageOutputStream ios = ImageIO.createImageOutputStream(outputFile)){ writer.setOutput(ios); writer.write(null, new IIOImage(image,null,null),iwp); ios.flush(); } finally{ writer.dispose(); } } private static ImageWriter getImageWriter(String ext) { Iterator iter = ImageIO.getImageWritersByFormatName(ext); if (iter.hasNext()) { return iter.next(); } throw new IllegalStateException("Unsupported " + ext); }

Here is a utility class for downloading resource and saving as file asynchronously . package utils.file { import flash.events.Event; import flash.events.EventDispatcher; import flash.events.ProgressEvent; import flash.filesystem.File; import flash.filesystem.FileStream; import flash.filesystem.FileMode; import flash.net.URLLoader; import flash.net.URLLoaderDataFormat; import flash.net.URLRequest; public class AsyncFileSaveDownloader extends EventDispatcher { public function AsyncFileSaveDownloader() { } public function download(url:String, path:String):void { var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.BINARY; loader.addEventListener(Event.COMPLETE, completeDownload); loader.load(new URLRequest(url)); function completeDownload(cevt:Event):void { l

There are a lot of way to copy file in Java. I have wrote sample codes for them. I think Java 7 way will be the normal & standard way soon!! import static com.dukesoftware.utils.common.ExceptionUtils.throwNotImplementedException; import static java.nio.file.StandardCopyOption.REPLACE_EXISTING; import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.io.Reader; import java.io.Writer; import java.net.URI; import java.nio.channels.FileChannel; import java.nio.file.Paths; import org.apache.commons.io.FileUtils; import com.google.common.io.Closeables; import com.google.common.io.Files; public enum Copier { GUAVA{ @Override public void copy(File src, File dest) throws IOException { Files.copy(src, dest); } }, JAVA7{ @

I wrote an image canvas class which can be automatically re-size image so that it fits the window. The code itself is pretty simple. package com.dukesoftware.utils.swing.others; import java.awt.Graphics; import java.awt.Image; import javax.swing.JPanel; public class AutoResizeImageCanvas extends JPanel{ private Image img; public void setImage(Image img){ this.img = img; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); final int panelWidth = getWidth(); final int panelHeight = getHeight(); g.fillRect(0, 0, panelWidth, panelHeight); if(img != null){ final int imgWidth = img.getWidth(null); final int imgHeight = img.getHeight(null); final double rW = (double)panelWidth / imgWidth; final double rH = (double)panelHeight / imgHeight; int newWidth; int newHeight; if(rW < rH){

This is my ant build script used for building app. You know FlashDevelop can build swf however it only compiles minimum classes directly used in the program. So I always run ant build script in order to compile all ".as" and ".mxml" source files If you would like to use my ant script, need some preparation.... Flex PMD: You can download Flex PMD, which is used in my ant script, from here . PMD xslt: I just downloaded official sourceforge PMD zip (the version is 5.0.0 when I wrote this article) and simply picked up some useful xslt from pmd-src-5.0.0/etc/xslt My project directory hierarchy is something like this... <?xml version="1.0" encoding="utf-8" ?> <project name="DukeSoftwareBuildAS3" default="all" basedir="."> <property name="root.dir" value=".." /> <property file="${root.dir}/proj.properties" /> <property file="build.prop
