  使用JMagick为图片打水印

   » ‎ eDWARD
  1. 为了保护图片的版权，我们经常需要在上传的照片上打上版权信息或图标，下面介绍利用JMagick在图片上做标记。引入JMagick需要的类库：

     import java.awt.Dimension;
     import java.awt.Rectangle;
     
     import magick.CompositeOperator;
     import magick.ImageInfo;
     import magick.MagickException;
     import magick.MagickImage;
     

  2. 下面介绍如何使用JMagick做标记：

     public static void mask(String logoPath, String srcPathName, String destPathName, int location, int scale) throws MagickException {
       int width = getWidth(srcPathName);
       int height = getHeight(srcPathName);
       int x = 0, y = 0;
       int w, h;
       w = scale * 70 / 100;
       h = scale * 65 / 100;
       boolean lc = true;
       if (width  width) {
         x = width - w * 2 - 10;
       }
       if (y  height) {
         y = height - h - 10;
       }
       if (lc) {
         ImageInfo info = new ImageInfo();
         MagickImage image = null;
         MagickImage mask = null;
         MagickImage dest = null;
         try {
           image = new MagickImage(new ImageInfo(srcPathName + “[0]“));
           mask = new MagickImage(new ImageInfo(logoPath));
           image.setFileName(destPathName);
           image.writeImage(info);
           dest = new MagickImage(new ImageInfo(destPathName));
           dest.compositeImage(CompositeOperator.AtopCompositeOp, mask, x, y);
           dest.setFileName(destPathName);
           dest.writeImage(info);
         } finally {
           if (image != null) {
             image.destroyImages();
           }
           if (mask != null) {
             mask.destroyImages();
           }
           if (dest != null) {
             dest.destroyImages();
           }
         }
       }
     }
     

     getWidth(String src) & getHeight(String src)

     public static int getWidth(String src) throws MagickException {
       MagickImage magImage = null;
       try {
         ImageInfo info = new ImageInfo(src + “[0]“);
         magImage = new MagickImage(info);
         Dimension imageDim = magImage.getDimension();
         return imageDim.width;
       } finally {
         if (magImage != null) {
           magImage.destroyImages();
         }
       }
     }
     
     public static int getHeight(String src) throws MagickException {
       MagickImage magImage = null;
       try {
         ImageInfo info = new ImageInfo(src + “[0]“);
         magImage = new MagickImage(info);
         Dimension imageDim = magImage.getDimension();
         return imageDim.height;
       } finally {
         if (magImage != null) {
           magImage.destroyImages();
         }
       }
     }

  A New And Improved YouTube For Mobile

   » ‎ YouTube
  Today we're excited to announce the official debut of YouTube for Mobile, featuring a new and improved mobile website, m.youtube.com! Until today, many of you who tried watching videos on m.youtube.com from your mobile phones may have longed to see a wider selection of videos and more community features that you've come to know and love on YouTube.com. Now you can, and here's what's changed:
  

  • Millions of videos: YouTube for Mobile now features tens of millions of videos, which includes most of the videos already available on YouTube.com and your own uploaded videos.
  • Community on the go: You can now access your YouTube account, your Favorites, your own uploaded Videos and your favorite Channels. You can also share, rate, and comment directly from the mobile website to other YouTube users.
  • Mobile phone uploads available within moments: Now if you upload videos from your phone to YouTube via email/mms, they will appear within moments on both m.youtube.com and www.youtube.com. This means you can easily share videos you capture on your phone with your friends and family. All you need to do is create a mobile profile at www.youtube.com/mobile.
  • Global: Global: YouTube for Mobile is available and localized for the UK, Italy, France, Spain, Netherlands, Poland, Brazil, Canada, Mexico, Australia, Hong Kong, Taiwan, New Zealand, Germany, and Russia.

  As long as your phone and mobile operator support streaming video, anyone can access YouTube for Mobile simply by going to 'm.youtube.com' in their phone browser. There are a couple requirements for supporting YouTube for Mobile:

  1. Your device has to support RTSP streaming. To determine if your mobile device supports this type of streaming, you may want to check your device's manual to find a description of its specifications.
  
  2. Your service carrier has to allow streaming videos. You may want to contact your carrier for more information about the availability of data streaming on your mobile device.

  In addition, we're also releasing a beta version of a YouTube for Mobile downloadable application. It's different from the YouTube for Mobile website (m.youtube.com) because it is a Java (J2ME) application you install on your phone, whereas m.youtube.com you access via your phone's web browser. The app is available in US and UK English and supports the following phones:

  • Sony Ericsson k800, w880
  • Nokia e65, n95, n73, 6110 navigator and 6120 classic

  To download the app, simply point your phone browser to m.youtube.com and if your phone's one of the above, you should be prompted to download and install the application.
  
  You may be wondering, "Is YouTube for Mobile the same as what's available on the Helio Ocean or Apple iPhone?" In a nutshell, yes -- YouTube for Mobile is all about bringing video to mobile phones. We believe in providing the best user experience possible for all users, which in some cases means different YouTube solutions for different phones. Overall, we're pretty excited about working with our partners and users to make YouTube for Mobile better and better over the next year.
  
  So point your phone browser to m.youtube.com and check out the latest changes today! And if you've got any feedback for us on YouTube for Mobile, leave us a comment on this blog entry or post a video response to the video below, in which YouTube for Mobile team members Andy and Dwipal tell you about the new features:
  
  
  
  Best,
  The YouTube Team

  Digg: New Algorithm Changes

   » ‎ Digg

  Just wanted to give everyone some insight into some of the changes we’ve been making this week. As we’ve talked about in the past, Digg’s promotional algorithm ensures that the most popular content dugg by a diverse, unique group of diggers reaches the home page. Our goal is to give each person a fair chance of getting their submission promoted to the home page. Since Digg began more than three years ago, we’ve constantly been making tweaks to the promotional algorithm and will continue to do so. Most of our additions go unnoticed, and others take a few days to normalize as we watch them run live on the site. We spend a lot of time analyzing the data and improving the system.

  As we point out in our FAQ, occasionally you will see stories in the upcoming section with 100+ Diggs - this is evidence of our promotion algorithm hard at work. One of the keys to getting a story promoted is diversity in Digging activity. When the algorithm gets the diversity it needs, it will promote a story from the Upcoming section to the home page. This way, the system knows a large variety of people will be into the story.

  As always, we welcome your thoughts and feedback.

  Digg on,

  Kevin

  Profile Clean-Up

   » ‎ Facebook
  Last week, you may have noticed a message on your profile page about the new "Extended Profile". The extended profile allows people to move unused profile boxes to an expandable part of their profile. Friends now click through to see the boxes located in the extended portion. We launched this feature in response to complaints from you that the profile had become too cluttered, and with so many applications, it was overwhelming to clean it up.
  
  Another complaint we heard was that it was becoming more and more difficult to find what you were looking for on a friend's profile. If you came to someone's profile just looking to find their phone number or email address, it was hard to find that information quickly.
  
  Extended profile has helped with this problem, and in addition, this week we've also decided to lock the "Personal Information" box—which includes contact information—into the spot beneath your Mini-Feed on your profile. You won't be able to move this box; we're hoping this makes it easier for your friends to get in touch with you when they want by not having to scour your entire profile for one small piece of info.
