Hi,

I found only 4 functions that needs to be fixed. See, pdf.c and png.c.
I still has a question that to do with this:
HB_FUNC( CAIRO_SURFACE_WRITE_TO_PNG )
{
#ifdef CAIRO_HAS_PNG_FUNCTIONS
cairo_surface_t * pSurface = hb_cairo_surface_param( 1 );
if( pSurface )
hb_retni( cairo_surface_write_to_png( pSurface, hb_parc( 2 ) ) );
#else
hb_cairo_surface_param( 1 ); /* Parameter validation */
hb_ret(); /* There is no good CAIRO_STATUS_* */
#endif
}
This function should return error code. 0 means "no error". There is no
good CAIRO_STATUS_* constant to indicate "no supported" (complete
http://www.cairographics.org/manual/cairo-error-status.html#cairo-status-t
). What action do you prefer return NIL, return -1, return 999 or some
number larger than existing cairo errors. Something else...

Mindaugas
