[. . . ] The view that the user specifies has an impact on how tables appear on the BlackBerry device. · In Column View, table rows that exceed the width of the device screen wrap to fit the width of the screen, and the row cells are stacked vertically. In BlackBerry Device Software version 4. 6 or later, the BlackBerry Browser ignores table layout in Column View. Users might be required to scroll horizontally to view the entire width of the table. 4. 6 or later · Design tables to fit the screen dimensions and use the HandheldFriendly <meta> tag to prevent scaling. Always test tables thoroughly to make sure they display as intended on the BlackBerry device in all BlackBerry Browser views. For a complete list of the supported table elements and attributes and the BlackBerry Device Software version in which support was introduced, see the BlackBerry Browser HTML Reference. Images The BlackBerry® Browser renders the following image types: · BMP · GIF, including animated GIFs · JPEG · PNG · TIFF 20 Fundamentals Guide Content rendering In Column View, images are scaled to fit the width of the BlackBerrydevice screen, less 5 pixels for the scrollbar. If users want to view the full image, they can click the Full Image menu item to download it. If the browser is communicating with the network gateway, the network gateway sends the image to the browser without scaling it. Users can specify a limit for the number times that animations can loop. Animated GIFs can repeat either the default value of 10 times or the number of times specified in the GIF repeat value. In BlackBerry® Device Software version 4. 2. 2 or later, users can specify the image quality for images rendered in the BlackBerry Browser. The lower the image quality, the faster the image is rendered. Progressive image rendering In BlackBerry® Device Software version 4. 2. 2 or later, the BlackBerry® Browser renders images progressively. When the browser retrieves a web page, a low quality version of each image displays quickly. After the entire web page is downloaded, the browser retrieves the additional image file segments from the network gateway. The low quality images are enhanced as the additional image file segments arrive, until they meet the image quality that is specified by the user. Progressive image rendering is available with the following browser configurations and the associated network gateways: · The BlackBerry Browser configuration and the BlackBerry MDS Connection Service network gateway · The Internet Browser configuration and the BlackBerry Internet Service Browsing network gateway Support for media streaming In BlackBerry® Device Software version 4. 3 or later, the BlackBerry® Browser supports streaming of audio and video files. The BlackBerry Browser supports the following media types: · · Video: WMV, h. 263 Audio: MIDI, MP3, MP4, Wav The browser supports media streaming over the HTTP or RTSP protocols. When a user clicks a link to an audio or video file, the user can open the file, save it to the media card or device memory, or cancel the download. If the user opens the file, the BlackBerry Browser opens the media application and the file begins streaming. When the content is finished streaming, the user can close the media application to return to the browser. Streamed content is not saved; users cannot replay media unless they download it again. The network gateway might limit the size of the file that can be streamed. [. . . ] Visit www. rim. com/patents for a list of RIM (as hereinafter defined) patents.
