Moves the view-coordinate origin to the specified physical point.
#include <graph.h>
struct _xycoord __far _setvieworg( short x, short y );
| x, y | New origin point |
The _setvieworg function moves the view-coordinate origin (0, 0) to the physical point (x, y).
The _xycoord structure, defined in GRAPH.H, contains the following elements:
| Element | Description |
| short xcoord | x coordinate |
| short ycoord | y coordinate |
The _setvieworg function replaces the _setlogorg function of Microsoft C version 5.1.
The function returns the physical coordinates of the previous view origin in an _xycoord structure, defined in GRAPH.H.
