Using GLC with Pango

[Bertrand Coconnier <bcoconni club-internet fr>]

Hi all,

I am the developper of QuesoGLC, a free implementation of SGI's GLC library (an 
OpenGL character renderer). See http://quesoglc.sourceforge.net

QuesoGLC's main purpose is to render characters (using OpenGL) but not to 
provide text layout management. From GLC's point of view, layout services are 
provided by libraries like Pango. My concern is how to interface smoothly 
QuesoGLC with Pango ?

I parsed Pango's web site but I could not figure out where the layout management 
ends and where the rendering task begins. I mean, should QuesoGLC support 
right-to-left rendering or does Pango sort out the characters so that they can 
be rendered left-to-right ? The same for vertical rendering ? Should QuesoGLC 
support all Unicode features (including the BiDi algorithm and/or the various 
normalizations) or does Pango take care of it ? Etc...

Genrally speaking, my question is what are the mimimal services that should be 
provided by QuesoGLC in order to render correctly the layout performed by Pango ?

Regards,

Bertrand.
