  • Feature update: Improved caching support for Internet Explorer.

  • Feature update: Stability improvements have been made to the ActiveX control for DjVu.
  • Feature update: Copy Image is supported for NT and Win2000.
  • Feature update: The plug-in no longer displays error messages related to "Stop" messages for child threads.
  • Documentation update: To customize the default placement of the toolbar use the <embed> or <object> tags in the HTML text of the web page as follows, TOOLBAR=top/bottom.
  • Documentation Update: To set the default alignment of the DjVu file in the viewing window type the <embed> or <object> tags in the HTML text of the web page using DOC_ALIGN="one of nine options".
  • Documentation update: To set the default rotation of a DjVu file in the viewing window type the <embed> or <<object> tag in the HTML text of the document using ROTATE=180 degrees (90 for 90 degree, 270 for 270 degree). The document rotates clockwise.
  • Documentation correction: Zoom in increases from 5% to 25%, then follows the settings from the Select Zoom drop down menu to 300%. Then the increases occur by 100% to a maximum of 1200%. The reverse occurs for Zoom Out.
  • Documentation correction - Zoom selected area only pertains to the Zoom in feature.
  • Document correction - The "passive" attribute, used with the <embed> or <object> tags, has been changed to properly reflect that it is not a binary attribute. To use the "passive" attribute, use "&passive;" without the "=yes/no" qualifiers.
  • Documentation correction - The span class="code"><object> tag may not be good for Win98/ME in combination with IE5.x, as in the following example.
    • <object type="image/x.djvu" data="foo.djvu" width=400 height=300>
    • <param name="src" value="foo.djvu">
    • </object>
    A better way to use object tag is:
    • <object classid="clsid:0e8d0700-75df-11d3-8b4a-0008c7450c4a" width=400 height=300>
    • <param name="src" value="foo.djvu">
    However, both examples work properly on WinNT/Win2000/XP and IE6.x


IV. Known Issues

The following known issues exist for the DjVu Web Browser Plug-in:

  • Systems which use a "VGA" pallete/theme may observe non-transparent backgrounds on the toolbar.
  • IE 6 SP 1 has a known issue, Q818857, which prevents the control from instantiating until the DjVu file it is viewing has completely downloaded. A supported fix is available from Microsoft. See http://support.microsoft.com/?id=818857.
  • Occassional rendering problems. Observed symptoms include (a) Annotations on the first page will not render (b) the image crops to the upper left corner. The work around is to either reload the page, either by reloading the document or by changing pages.
  • When setting the "Page=<id>" property using the CGI-bin type arguments, the Page property must be set *last*. The problem does not occur when setting "Page=#".
