Ignacio, you Gooroo!
It works! Cool indeed! Makes me enthusiastic about making add-ons. And perhaps one day I might learn how to really do it.
In the meantime one could think of what other viewers to integrate…
scribd has a flash-based viewer for many office formats, but is totally closed source and i believe they even own the servers. However it displays:
* Adobe PDF (.pdf)
* Adobe PostScript (.ps)
* Microsoft Word (.doc, .docx)
* Microsoft PowerPoint (.ppt, .pps, .pptx)
* Microsoft Excel (.xls, xlsx)
* OpenOffice Text Document (.odt, .sxw)
* OpenOffice Presentation Document (.odp, .sxi)
* OpenOffice Spreadsheet (.ods, .sxc)
* All OpenDocument formats
* Plain text (.txt)
* Rich text format (.rtf)
ThinkFree Unipaper does the same, software-as-a-service-style.
Both are unusable in the context of openGoo because of their digital rights restrictions. But I take them as proof of concept that it can be done nicely.
Then of course it's possible to integrate the Adobe Acrobat reader into a webpage.
Ajax Document Viewer supports the above plus ca. 50 deprecated digital fax file formats…
…and what about web based viewers for CAD files any most other things done with extra plugins…
and certainly there will be more…!
(I'll make a note on my internal wishlist)
