The fonts developed using Volt do not become proprietary because the tool is. The Source version of the font will be according to the Volt conventions and GUI but you can open the binary form of the font in FontForge and make it into FontForge Source form, I suppose. Prof Nagarjuna team developed all his fonts under FontForge. I remember that I had a showdown with Prof R K Joshi over this issue. At the end when all the fonts were made using Volt, RK comes up with the idea that now we will do it in FontForge as Volt is proprietary.

Let me quote to you excerpts from The IndiX Project LICENSE for software: The IndiX Project LICENSE ------------------------- Copyright 2004-2008 by Centre for Development of Advanced Computing, Mumbai Introduction ============ The IndiX Project is distributed in several archive packages; some of them may contain, in addition to the IndiX shaping engine, various tools and contributions which rely on, or relate to, the IndiX Project. This license applies to all files found in such packages, and which do not fall under their own explicit license. The license affects thus the IndiX shaping engine, the test programs, documentation and makefiles, at the very least. This license was inspired by the BSD, Artistic, and IJG (Independent JPEG Group) licenses, which all encourage inclusion and use of free software in commercial and freeware products alike. It is the same as the FreeType license, FT-license.txt. As a consequence, its main points are that: o We don't promise that this software works. However, we are interested in any kind of bug reports. (`as is' distribution) o You can use this software for whatever you want, in parts or full form, without having to pay us. (`royalty-free' usage) o You may not pretend that you wrote this software. If you use it, or only parts of it, in a program, you must acknowledge somewhere in your documentation that you've used the IndiX code. (`credits') We specifically permit and encourage the inclusion of this software, with or without modifications, in commercial products, provided that all warranty or liability claims are assumed by the product vendor. Each font has a license which is downloadable. Basically it says that the font is GPL 2. No separate wording of the license is given The extract from the RaghuHindi license is: Copyright RaghuHindi font Original Version 1.00 (2005) by Centre for Development of Advanced Computing, Mumbai. RaghuHindi font Original Version 1.00 (2005) has been released under GNU GPL Version 2. Again we had a tough time getting the font design to be placed under GPL V2. IndiX-2 project is completed and closed. Its products are available as downloads but officially no more support is provided. But I still respond to queries, and suggestions from a handful of users. I actively try to promote the viewpoint in the Unicode, OpenType and IndLinux public groups. I had written several letters to Owen Taylor and later to Behdad Esfabod, but I am disappointed that both of them did not reply. > >> Interesting idea, may be suitable for text terminal as well in linux. > Your approach seems to be updating XFree86 libraries.

The IndiX library has also been implemented in other software like our printools. Interestingly, Mozilla browser worked without any modifications on IndiX distribution (Knoppix with IndiX enable XFree86 and IndiX fonts. This is the Live CD). So our approach is not updating XFree86 libraries. I believe that the Intelligent font approach would work with all complex scripts. I am sure it works with the 9 Indic scripts. So modifying Pango or ICU will only be a simplification. You can forget about parsing each character in a syllable and tagging it with a four letter Feature tag. vinod kumar -- पृथिवी सस्यशालिनी the earth be green |
