Dinkelhopper has posted three new Opus viewer plugins to the Resource Centre:
64-bit users should note that these plugins are 32-bit only, at least for now.
If you need alternatives that work with 64-bit:
CSV can be shown through the ActiveX plugin if you have Excel installed. (May also work with OpenOffice.org instead of Excel.)
Update: Not sure where my head was at when I wrote this... I don't think using ActiveX/Excel for CSV works very well as, from memory, you get an annoying format conversion dialog when you open the files. That would be why I didn't include .CSV in the default config of the ActiveX plugin.
Postscript should be visible in the ActiveX plugin if you have Ghostscript installed and add the appropriate file extensions to the plugin:
The Ghostscript installer includes a postscript viewer for Internet Explorer and the ActiveX + Preview + Office + Web plugin for Opus can be configured to take advantage of that. Go to Preferences - Plugins - Viewer Plugins, select the ActiveX + Preview + Office + Web plugin, click Configure, then add the .ps and .eps extensions under the Internet Explorer (32-bit) section. Those file extensions will then be displayed in the Opus viewer pane via IE.
Update: Turns out this is incorrect. Ghostview does not provide a viewer that works in Internet Explorer, despite its webpage suggesting it does.
- Fonts can be viewed via the Font preview handler which comes installed with Vista. (This is via the ActiveX plugin as well but doesn't require any configuration to enable.)
