[AGG] PDF and AGG

[Salman K. <sk...@ta...>]

Can someone tell me which kinds of shading does AGG support from the PDF 
specification?  The list from version 1.3 of PDF reference is:

1.  Function-based shading
2  Axial shading
3.  Radial shading
4  Free Form Gouraud
5.  Lattice-from Gouraud
6  Coons patch mesh
7  Tensor product patch mesh


Also from the PDF specification, one can use character glyphs as clipping 
paths.  One can also apply patterns and shadings to character glyphs.  I was 
thinking about using freetype for all font rendering.  If one uses freetype, 
then this would not be possible.

Will it be enough if I can somehow convert the outline of the character glyph 
from freetype into a path that AGG can understand?  Then instead of having 
freetype do the rendering and blending it on top the agg graphics, one can 
let AGG render the outlines?  Am I making any sense?

BTW, I would like to start a project that can create PDF using C++.  One 
should be able to do the drawings in user-space coords using AGG and then 
export the result as a PDF file.  Right now, I am not interested in 
supporting all the color specifications that PDF specifies....just device 
dependent RGB is enough for me.  Anyone already got a similar C++ based 
project that I might contribute to?
