Extension:Media Viewer/About/zh



媒体查看器（Media Viewer）可以通过加大页面中缩略图的尺寸、减小图像失真的方法，帮助改善于维基百科、维基共享资源和MediaWiki上多媒体资源的视觉体验. 它是由维基媒体基金会的新Multimedia小组研发的，现在已经拥有一个Beta版本，用于测试，正如您所见，是界面右上角测试功能的一部分.

您现在可以在维基共享资源、MediaWiki.org和Meta.Wikimedia.org上测试. 基于测试结果，我们将在2013年11月21日向所有的维基页面发布这个扩展功能.

您现在可以在所有的维基页面测试V0.1版的媒体查看器. 这是媒体查看器的第一个版本是，还处在研发的早期阶段，且拥有许多已知的漏洞. 我们已经邀请社群进行测试反馈，所以我们能一同在接下来的一个月改进这个扩展功能.

新版本V0.2已经可以在MediaWiki.org上进行测试，点击进入测试页面（别忘了在您的“测试功能”页面中开启媒体查看器）. 如果您想先睹为快，看看下面的章节.

如果您现在已经试用了这个扩展功能，我们邀请您加入讨论，发表您的看法. 诚挚欢迎您的光临！

为什么使用媒体查看器？
这个小工具的目的是：
 * 提供更好的多媒体视觉体验，以迎合用户的需求；
 * 用一个更大的尺寸显示图片；
 * 避免用户点击缩略图时产生的不必要的麻烦（例如，一个新页面会覆盖原页面）

媒体查看器的目标是服务维基百科、维基共享资源和其它的MediaWiki页面上所有的使用者. 值得注意的是，媒体查看器目前只能查看图片，因为我们现在正在使用Kaltura播放器来播放视频和音频. 但是随着事件的推移，我们想要使用一个相同的UI界面，来播放所有格式的多媒体文件.

目前的特色包括：
 * 当您点击图片时，以更大的尺寸显示它们；
 * 在原页面即时打开多媒体文件；
 * 大尺寸图片，无失真（在“灯箱”模式中）；
 * 显示一些关于图片的作者、版权等信息（灯箱层）；
 * 图片可以全屏显示.

媒体查看器是怎样工作的？




媒体查看器提供两种不同的显示模式，您可以通过点击右上角的小箭头进行切换.

灯箱模式
“灯箱”显示模式的特点包括：

使用大尺寸显示图片，覆盖在原页面上，背景是半透明的白色界面. 这使得图片更加凸显，并避免了繁杂文字带来的干扰.
 * 图片

For the first release, we are offering these simple tools:
 * Tools
 * Close button (goes back to article view)
 * Full screen button (expands into full-screen view)
 * Lightbox button (returns to smaller image in browser lightbox)

Here is the information that is shown above the image (see mockup):
 * Primary Info
 * File name (Zonotrichia atricapilla)
 * Author (e.g. Alejandro Erickson)
 * Source (e.g. Bird Institute)
 * License Info (e.g. CC-BY-SA-2.0) (or link to license info)

Here is the information that is shown below the image:
 * Secondary Info
 * Site name and link (e.g. Wikimedia Commons)
 * Description
 * Uploader name (e.g. Smallbones)
 * Creation Date (e.g. 12 April, 2012)

Full Screen View
The 'full-screen view' for this tool will show a large image across the entire screen, with minimal information and buttons available on hover, as shown in this mockup.

This is the view that lets you focus exclusively on the image, with no other distractions. When you click on the full screen icon, you see the largest version of the image that fits within the user's screen. The image is displayed across the entire screen (not just the browser window), set against a pure white background color that only shows the image. In this mode, you only see the file name and the author/source/license near the image, as well as link to Commons.

When will it be released?
A first beta version of Media Viewer will be released gradually in November, as part of Beta Features, a new experimental program that will enable users to opt-in to test new beta features before they are released widely.

Media Viewer can now be tested by logged-in users on MediaWiki.org, on Meta.Wikimedia.org and on Wikimedia Commons. Based on test results, we aim to release it on all wikis worldwide on 21 November, 2013.

In the first release, the Media Viewer will only support the most widely used image file formats (e.g.: JPEG, GIF, PNG, TIFF, SVG), when users click on thumbnails in articles, galleries and category pages. In future releases, we plan to add support for PDF files, as well as audio and video files.

How can I help?


Can you help us test Media Viewer in coming days? This beta feature is now available for early testing by logged-in users on MediaWiki.org, on Meta.Wikimedia.org and on Wikimedia Commons.

To test this feature, click on the small 'Beta' link next to 'Preferences' in your personal menu. Then check the box next to 'Media Viewer' in the new BetaFeatures section of your user preferences — and click 'Save' (see screenshot). You can turn off any this options anytime, by reversing these steps. To test a variety of images in different file formats, you might like to check this lightbox demo page.

Try out Media Viewer and let us know what you think on this discussion page. If you find any technical bugs, please report them here on Bugzilla. Based on your feedback, we will improve this feature in coming weeks.

You can test Media Viewer with different file formats on this special test page.

Next Version


The next version 0.2 of Media Viewer will focus on a 'full-width design' as the default view, to provide a more immersive user experience. When you click on a thumbnail, you would see a larger image than you do now, with only a small sliver of meta-data at the bottom of the page, as shown in this mockup, also shown to the right.

The goal is to display images to fill the browser window as much as possible, aiming for up to 100% of the browser window width and up to 90% of its height. To speed up this display, we will try to fetch the thumnbnail size that is closest to 100% of the screen width but no more than 90% of the screen height (instead of asking the server to pre-render custom sizes, which is too time-consuming). Note that may propose different display rules for portraits and images with special aspect ratios.
 * Image Display

The meta-data would be shown below the image, and only include a few items above the fold (file name, license, author, source and uploader). But you would be invited to scroll down to see a lot more meta-data below, with a clear affordance letting know how to get more info. The mockups below show examples of how this might work.
 * Meta Data

Tools would be shown below the image (thank, flag, share, full-screen) (except for the 'X' close icon and next/previous arrows, which could be shown over the image on hover, as suggested by best practices from other media sites). Next, we will also mockup audio-video playback as well in this context (play/pause, rewind, fast-forward, volume, scrollable timeline).

Desktop Mockups
Here are some preliminary mockups of designs we're exploring for desktop computers.

These mockups will be adjusted based on community feedback.

Mobile Mockups
Here are some preliminary mockups of designs we're exploring for mobile devices.

These mockups will be adjusted based on community feedback.
