Evas_Coord | evas_coord_screen_x_to_world (Evas *e, int x) |
Convert/scale an ouput screen co-ordinate into canvas co-ordinates. | |
Evas_Coord | evas_coord_screen_y_to_world (Evas *e, int y) |
Convert/scale an ouput screen co-ordinate into canvas co-ordinates. | |
int | evas_coord_world_x_to_screen (Evas *e, Evas_Coord x) |
Convert/scale a canvas co-ordinate into output screen co-ordinates. | |
int | evas_coord_world_y_to_screen (Evas *e, Evas_Coord y) |
Convert/scale a canvas co-ordinate into output screen co-ordinates. |
|
Convert/scale an ouput screen co-ordinate into canvas co-ordinates.
x parameter and converts it into canvas units, accounting for output size, viewport size and location, returning it as the function return value. If e is invalid, the results are undefined.Example: extern Evas *evas; extern int screen_x; Evas_Coord canvas_x; canvas_x = evas_coord_screen_x_to_world(evas, screen_x); |
