Re: [Indic-computing-devel] Re: [Kannada] A few kannada bug fixes to qt-3.2.1

[Krishnamurthy N. <kn...@ya...>]

Hi Arun,

The fundamental issue is that the glyph composition
and rendering logic is 'hardcoded' in C code of each
application, that to for a 'given' font. A more
broad-based approach would be to provide generic X
input methods for Indian languages. Pls take a look at
the infrastructure projects under indic-computing on
sourceforge that we have done/are doing (font
annotation, generic transliteration library, study of
various scripts and languages to develop a generic X
input method framework and so on). Having developed
and tested out the generic rule-based framework for
four Indian languages (Hindi, Telugu, Kannada and
Tamil), with all the complexity in the rules (given in
a text file to the translib library) and zero C code
that is specific to any language/script, I am
convinced that 
any language/script specific peculiarities (like the
reph case in Kannada, split vowel signs in Devenagari
and Tamil, multiple representations for the same input
etc etc) can be handled without any special coding at
the app level (gnome, qt or whatever). 

Pls visit the indic-computing projects, especially the
infrastructure projects and give your comments and
contribute to this base work. Thanks.

cheers,
Nagarajan
