I have a C++ program that uses cairomm, and I'd like to use librsvg with
it to render SVG files to Cairo surfaces. However, librsvg is in C, and
rsvg_handle_render_cairo expects a cairo_t value, while cairomm's
Cairo::Context doesn't give access to the underlying C type (it's
protected). I tried subclassing Cairo::Context and implementing a
function that returned a pointer to the underlying cairo_t type, but it
doesn't seem to be working.
Code is as follows:
main.cpp: https://paste.gnome.org/p9fzmosnu
Makefile: https://paste.gnome.org/p6qswmxgr
mor.glade: https://paste.gnome.org/phlvgqqt5
It just prints
(mor:7839): librsvg-CRITICAL **: rsvg_handle_render_cairo_sub: assertion
'handle != NULL' failed
repeatedly, and doesn't render anything.
Any help would be appreciated.
