Hi
Does anybody know what the Current Transformation Matrix (CTM) is for
the Cairo::Context i get from
virtual bool on_draw(const Cairo::RefPtr<Cairo::Context>& cr);
Is there a way to look at the elements of a Cairo::Matrix?
Thank You
Jody
Cairo::Context contains the methods
void get_matrix(Matrix& matrix);
void get_matrix(cairo_matrix_t& matrix);
Matrix get_matrix() const;
Cairo::Matrix derives from cairo_matrix_t,
class Matrix : public cairo_matrix_t
{
............
};
and cairo_matrix_t is an open struct,
typedef struct _cairo_matrix {
double xx; double yx;
double xy; double yy;
double x0; double y0;
} cairo_matrix_t;
