cairo_get_current_point.RdGets the current point of the current path, which is conceptually the final point reached by the path so far.
cairo_get_current_point(cr, x, y)
| cr | [ |
|---|---|
| x | [ |
| y | [ |
The current point is returned in the user-space coordinate system. If there is no defined current point or if cr is in an error status, x and y will both be set to 0.0. It is possible to check this in advance with cairo_has_current_point().
Most path construction functions alter the current point. See the following for details on how they affect the current point: cairo_new_path(), cairo_new_sub_path(), cairo_append_path(), cairo_close_path(), cairo_move_to(), cairo_line_to(), cairo_curve_to(), cairo_rel_move_to(), cairo_rel_line_to(), cairo_rel_curve_to(), cairo_arc(), cairo_arc_negative(), cairo_rectangle(), cairo_text_path(), cairo_glyph_path(), cairo_stroke_to_path().
Some functions use and alter the current point but do not otherwise change current path: cairo_show_text().
Some functions unset the current path and as a result, current point: cairo_fill(), cairo_stroke().
