NAME

vdc_to_dc − transform a virtual device coordinate point to a device coordinate point using the current VDC-to-DC transformation. 

SYNOPSIS

C Syntax:

void vdc_to_dc ( fildes, vdcx, vdcy, vdcz, dcx, dcy, dcz )
int fildes;
float vdcx, vdcy, vdcz;
int *dcx, *dcy, *dcz;

FORTRAN77 Syntax:

subroutine vdc_to_dc ( fildes, vdcx, vdcy, vdcz, dcx, dcy, dcz )
integer*4 fildes
real vdcx, vdcy, vdcz
integer*4 dcx, dcy, dcz

Pascal Syntax:

procedure vdc_to_dc ( fildes:integer; vdcx, vdcy, vdcz:real;
var dcx, dcy, dcz:integer );

DESCRIPTION

Input Parameters

fildes Integer file descriptor returned by gopen when an I/O path to a graphics device is opened. 

vdcx, vdcy, vdcz
Defines a point in virtual device coordinates to be transformed into device coordinates.

Output Parameters

dcx, dcy, dcz Transformed point in device coordinates. 

Discussion

Vdc_to_dc is used to transform a point in virtual device coordinate values to device coordinates.
