Translate coordinates to view coordinates.
#include <graph.h>
struct _xycoord __far _getviewcoord( short x, short y );
struct _xycoord __far _getviewcoord_w( double wx, double wy );
struct _xycoord __far _getviewcoord_wxy( struct _wxycoord
__far *pwxy1 );
| x, y | Physical point to translate | |
| wx, wy | Window point to translate | |
| pwxy1 | Window point to translate |
The _getviewcoord routines translate the specified coordinates (x, y) from one coordinate system to view coordinates and then return them in an _xycoord structure, defined in GRAPH.H. The _xycoord structure contains the following elements:
| Element | Description |
| short xcoord | x coordinate |
| short ycoord | y coordinate |
The various _getviewcoord routines translate in the following manner:
| Routine | Translation |
| _getviewcoord | Physical coordinates (x, y) to view coordinates |
| _getviewcoord_w | Window coordinates (wx, wy) to view coordinates |
| _getviewcoord_wxy | Window coordinates structure (pwxy1) to view coordinates |
In Microsoft C version 5.1, the function _getviewcoord was called _getlogcoord.
The _getviewcoord function returns the coordinates as noted above. There is no error return.
