GET STROKE
CALL SEQUENCE
void pget_stroke (view_index, stroke)
OUTPUT PARAMETERS
Pint *view_index,
Ppoint_list *stroke
ARGUMENTS
- view_index,
- View index
- stroke
- Stroke position
TYPES
typedef struct {
Pint num_points; /* number of Ppoints in the list */
Ppoint *points; /* list of points */
} Ppoint_list;
typedef struct {
Pfloat x; /* x coordinate */
Pfloat y; /* y coordinate */
} Ppoint;
PHIGS STATE
(PHOP, WSOP, *, *).
EFFECT
This function restricts the 3D get stroke function to 2D, the z is
ignored.
ERRORS
- 3
Ignoring function, function requires state (PHOP, WSOP,*,*)
- 259
- Ignoring function, the input device class of the current input report does
not match the class
