[gtkmm] i am still looking for a reporting C++ library

[cedric <cedric probesys com>]

Hi !
i'm still looking for a "reporting C++ library" or "graphic C++ library" 
which is free (GPL ...) and OS independent (windows+linux).

I tried libharu but that one is not documented and very difficult to use.
I also tried a C library named plot_ps but i can't put image in the 
PostScript file :o(

Cause i'd like to put a logo and a table (of sold articles), address of 
the customer, the company ...
So the library that i'm looking for would generate PS or PDF or PNG or 
BMP or TIFF or whatever which can be printed.

This is for my free software made in GTKMM : I want it to have the 
capability of printing bills, estimates ... etc ...

Thanks !

Seb.
