copied!<p>I am trying to save a JPEG image from a URL to a file with Java. URL: <a href="http://150.214.222.100//axis-cgi/mjpg/video.cgi?resolution=640x480&compression=1&duration=1&timeout=&dummy=garb" rel="nofollow noreferrer">http://150.214.222.100//axis-cgi/mjpg/video.cgi?resolution=640x480&compression=1&duration=1&timeout=&dummy=garb</a></p> <p>I tried the following: 1) </p> <pre><code>Image image = fetchImage(urlNorthView); saveImage2Disk(image); public static Image fetchImage( URL u ) throws MalformedURLException, IOException { Toolkit tk = Toolkit.getDefaultToolkit(); return tk.createImage(u ); } private void saveImage2Disk(Image Image) throws IOException{ File outputFile = new File("urlNorthView"+Calendar.getInstance().getTimeInMillis()+".jpg"); BufferedImage bufferedImage = new BufferedImage(Image.getWidth(null),Image.getHeight(null), BufferedImage.TYPE_INT_RGB); Graphics2D g2 = bufferedImage.createGraphics(); g2.drawImage(Image, null, null); ImageIO.write(bufferedImage, "jpg", outputFile); } </code></pre> <p>=> Exception:"Width (-1) and height (-1) cannot be <= 0"</p> <p>2) </p> <pre><code>inputStream2Disk((InputStream) urlNorthView.getContent()); private void inputStream2Disk(InputStream in) throws Exception{ File outputFile = new File("urlNorthView"+Calendar.getInstance().getTimeInMillis()+".jpg"); OutputStream out=new FileOutputStream(outputFile); byte buf[]=new byte[1024]; int len; while((len=in.read(buf))>0) out.write(buf,0,len); out.close(); in.close(); } </code></pre> <p>The file is somehow broken. When I open it with <a href="http://en.wikipedia.org/wiki/Kate_%28text_editor%29" rel="nofollow noreferrer">Kate</a>, I can read:</p> <blockquote> <p>--myboundary Content-Type: image/jpeg Content-Length: 38256 ....</p> </blockquote> <p>There should not be any text in a binary file.</p> <p>What could the problem be?</p>
