NAME

flush_matrices − remove all matrices, except the vdc-to-device matrix, from the matrix stack. The current transformation matrix is then the vdc-to-device matrix. 

SYNOPSIS

C SYNTAX

void flush_matrices(fildes);
int fildes;

FORTRAN77 SYNTAX

        subroutine flush_matrices(fildes)
        integer*4 fildes

PASCAL SYNTAX

procedure flush_matrices(fildes : integer);

HP-UX COMPATIBILITY

Level: HP-UX/STANDARD

DESCRIPTION

INPUT PARAMETERS

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

DISCUSSION

All matrices in the matrix stack are removed and the current transformation matrix is the vdc-to-device matrix.  This is the matrix that converts from Virtual Device Coordinates to Device Coordinates and is different from device to device.  World coordinates are then equivalent to Virtual Device Coordinates.
