go_cairo_convert_data_from_pixbuf ()

void
go_cairo_convert_data_from_pixbuf (unsigned char *dst,
                                   unsigned char const *src,
                                   int width,

                                   int rowstride);

Converts the pixel data stored in src in GDK_COLORSPACE_RGB pixbuf format to CAIRO_FORMAT_ARGB32 cairo format and move them to dst . If src == dst , pixel are converted in place.
