Cannot read a DejaVu file

[jay]

I am a new user, and am trying to convert a .djv file to pdf format.

When I click "convert" I get the message "format of the file (filename) could not be determined." It is a djv file, and has that extension. The plugin is installed and shows up on the list.

Any suggestions? Thanks very much for the great job you are doing.

Djvu plugin can not read new format of djvu

(problem also mentioned here and here)

Are there any chances to get plugin working in 2009? I know, that you simply cannot find the library to use. DjVuLibre is published under GNU, so you can't use it unless you make xnview OpenSource (which is not bad, but I also understand why you don't want to). Maybe you can talk to them and convince, that BSD licence or LGPL will create only benefits for both sides.

The problem is still there with XnView 1.97.2 and Xdjvu.dll 1.96.0.0 (downloaded from http://www.xnview.com/download/plugins/djvu.zip on 8th April 2010 and extracted the DLL into XnView's PlugIns directory).

But AFAIK, it would be perfectly legal for a DjVu plugin to use a library under GPL if the DjVu plugin is itself licensed under GPL and is distributed separately of XnView (e.g. on the XnView plugin download page, where I downloaded the current plugin that didn't work). This way the one who mixes GPL-d and non-GPL-d software would be the end user, but the GPL does not restrict making private modifications but only distributing the derived software (I am not a lawyer, but see e.g. http://en.wikipedia.org/wiki/Gpl: "Copyleft applies only when a person seeks to redistribute the program."). The only thing that ties the (non-GPL) XnView setup package and the (GPL-d) plugin would be the XnView plugin API, which should thus be available under a license that allows both GPL-d and closed-source derivatives. That seems to be the case already, as the API seems to be available on XnView homepage as the "Plugins SDK" ZIP which, I assume, is in public domain.

@Pierre: Could you please add a note in the list of supported formats that clearly states that new DJVU format is not supported by XnView?

that clearly states that new DJVU format is not supported by XnView?

"new format" is format starting from which version? And what is needed to support it?

The DjVu plugin use old library from lizartech, so new format use OpenDjvu
