I ran into the same issue. Can you please explain your solution and how to
implement it?
cairo_status_t writeSvg(void *closure, const unsigned char *data, unsigned int
length)
{
...
}
...
void main() {
cairo_surface_t *surface=0;
cairo_t *cr=0;
surface = cairo_svg_surface_create_for_stream(writeSvg, &truncated, 390, 60);
cr = cairo_create(surface);
cairo_set_source_rgb(cr, 0, 0, 0);
cairo_select_font_face(cr, "Sans", CAIRO_FONT_SLANT_NORMAL,
CAIRO_FONT_WEIGHT_NORMAL);
cairo_set_font_size(cr, 40.0);
cairo_move_to(cr, 10.0, 50.0);
cairo_show_text(cr, "Hello World.");
cairo_show_page(cr); // writeSvg not invoked here!
cairo_move_to(cr, 10.0, 50.0);
cairo_show_text(cr, "Knowledge is Power.");
cairo_surface_destroy(surface);
cairo_destroy(cr); // writeSvg invoked here!
